Value addition refers to the process of increasing the economic value of a product, service, or commodity through various means, such as: Processing: Transforming raw materials into a more refined or finished product.
Enhancement: Improving the quality, appearance, or functionality of a product.
Differentiation: Creating unique features, branding, or packaging to distinguish a product from others.
Innovation: Introducing new or improved products, services, or processes. Value addition in medicinal and aromatic plants (MAPs) is essential to enhance their economic value, quality, and marketability. Here are key reasons why value addition is necessary:
Enhanced economic value
Value addition increases the economic value of MAPs, benefiting farmers and stakeholders. Primary processing and value addition are crucial in this regard. For instance, drying, cleaning, grading, and packaging are essential steps in adding value to MAPs.
Improved quality and shelf life Value addition helps preserve the bioactive compounds and aroma of MAPs, extending their shelf life. Techniques such as drying, extraction, and storage in airtight containers are vital in maintaining the quality of MAPs.

Abstract
India, with 70% of its population reliant on agriculture, faces a challenge in rural development due to a modest 3.64% agricultural growth rate against a target of 4%, lagging behind the 7-8% growth in manufacturing and services. This disparity leaves rural communities unable to fully benefit from national economic progress. Promoting agripreneurship is a vital strategy to harness rural resources, enhance livelihoods, and achieve balanced economic development. Opportunities abound in agricultural inputs, farming technologies, output processing, and allied sectors like dairy, poultry, horticulture, and sericulture. However, challenges such as limited awareness, weak entrepreneurial culture, poor infrastructure, and insufficient government focus hinder progress. Strategic interventions in these areas can unlock the potential for sustainable rural growth and economic inclusivity.

Abstract
Rural women in India play a pivotal role in economic development, particularly through their significant contributions to dairy farming, a key enterprise in rural economies. Despite their extensive involvement in dairy activities such as fodder collection, milking, and animal care, their labour often remains non-monetized, limiting economic empowerment. Dairy farming, bolstered by initiatives like Operation Flood, has made India the world’s largest milk producer, offering profitable opportunities for rural women. Entrepreneurship in dairy farming can economically empower women, granting them decision-making autonomy and social recognition. Government schemes, NGOs, and institutions like KVKs facilitate this through training, formation of Women Dairy Cooperatives, and Self-Help Groups. Success stories from Chittoor, Jajpur, and Valsad highlight women leveraging dairy enterprises for financial independence and community inspiration. Promoting women’s entrepreneurship in dairy farming through skill development and market access is crucial for their socio-economic upliftment.

Abstract
Milk, recognized globally as a complete food, is rich in essential nutrients like calcium, amino acids, and bioactive compounds, offering numerous health benefits such as antimicrobial, antihypertensive, and anti-carcinogenic properties. India, the world’s largest milk producer with 170 million tonnes annually (20% of global production), is witnessing rapid growth in its dairy industry, projected to reach a market value of Rs. 10 trillion by 2025. The sector, driven by modernization, cooperatives, and increasing consumer demand for value-added products like ghee, cheese, and probiotics, presents vast entrepreneurial opportunities in dairy farming, processing, retail, and machinery manufacturing. However, challenges such as poor hygiene, inadequate cold chains, and livestock health issues hinder quality and scalability. Emerging processing technologies and adherence to FSSAI regulations can enhance product quality and market potential, making dairy enterprises a cornerstone of India’s food industry and rural economy.

Introduction
Broadly we can say environment means nature. Nature is the mother of the ecology. If we really care for integrity and overall health of nature, then the environment should be preserved and protected from all kinds of threat. The industrial revolution started in the late 18th and 19th centuries as a significant economic development. Industrialization was accelerated by the introduction of power-driven machinery.
This revolution affected the environment a lot. The main cause of this abundant increase in population which obviously increase living standards. To fulfill this high living standard and maintain living at per, we are prompted to deplete natural resources. The random and careless use of chemicals and fuel in industrial sector cause increased incident of air and water pollution. Business venture contributes a major part of the economic development and prosperity of the country as well as provides employment generation and wealth generation but on the other hand cause environmental deterioration.
So we should encourage business venture, entrepreneurial development and industrialization but without harming nature. In order to proceed business venture through smooth way and in a sustainable manner, some legislation or guidelines should make to protect our environment while we are there to maintain entrepreneurial flow.

Abstract
With India’s population projected to reach 1.7 billion by 2050, increasing food grain production by 5.5 million tonnes annually is critical to meet food demands. Despite agriculture engaging over 60% of India’s workforce, it is often perceived as low-tech and unprofitable, dominated by small family farms. Recent economic liberalization, changing consumer preferences, and stringent regulations have spurred agripreneurship, fostering innovation and market-driven enterprises. Success stories from Maharashtra, such as Shri Arun Wandre’s bamboo cultivation venture, Ms. Kavita Bidwe’s agri-input supply center, Shri Prashant Madghe’s Krishi Doot extension services, AgroStar’s mobile-commerce platform, Dnyaneshwar Bodke’s floriculture group, and the organic farming venture of Satyajeet and Ajinkya, highlight how entrepreneurial approaches can transform agriculture into profitable, sustainable businesses. These cases underscore the potential of agripreneurship to enhance rural livelihoods, strengthen the economy, and address challenges like lack of awareness, poor infrastructure, and inadequate institutional support.

Abstract
The growing youth population in developing countries, particularly in agriculturedominated economies, presents a demographic dividend that remains underutilized due to skill mismatches and unemployment. Despite agriculture engaging nearly 50% of the workforce, it is often stigmatized as a low-skill profession, necessitating up-skilling and knowledge enhancement to transform it into a profitable, modern enterprise. Government initiatives in India, such as PMKVY, Start-up India, Mudra Yojana, ARYA, and Student Ready, aim to foster skill development and agripreneurship to align with global market trends. This paper examines challenges in leveraging this demographic potential, including outdated interventions and societal perceptions, and proposes visionary reforms to enhance training, promote equity, and mainstream agri-preneurship for sustainable economic development.

In history, some developments were possible through belief and scientific study with evidence to support their claims. Our ancestors made ways of surviving on earth by varying the raw materials and tools. Science had absolutely no place, and all discoveries were derived through the trial-and-error method. The same was for agriculture, tracing back to our roots, the farming system was highly
dependent on the on-farm inputs. However, with the timeline of evolution, the exponential growth of the population demanded speedy growth in agricultural production giving rise to Green Revolution technologies (GRTs) in the mid- 1960s, which introduced high-yielding varieties of crops that were responsive to higher dosages of chemical fertilizers and irrigation and persuaded farmers to resort to intensive monocropping. Since the onset of GRTs in the mid-1960s, food production in India has risen five to ten-fold (Dasgupta, 1977).
However, while the past few decades have seen substantial ‘green revolution’ advances, I admit, the hazards have kept themselves hidden and well concealed--of these are significant adverse impacts on the natural resources, agriculture and its produce and indeed extend to human health (Koner & Laha, 2021). There is further proof that increasing dosages of chemical fertilizers led to an emergence of pest resurgence; pesticides residues considerably exceeding permissible limits contaminated drinking water and/or air often, a drop in biodiversity, nitrogen leaching and groundwater pollution, and soil heavy-metals build-up are very common in intensive agriculture regions (John & Babu, 2021). While such issues contributed to suicides in rural India, their unwarranted use also diminished pollinator populations (Baron et al.,  2017). There are many measures to ease the overwhelming cost burden upon farmers on account of farming and rising costs of cultivation. It pertains to the increased input subsidies made by various state and central governmentsthe fertilizer subsidy, the free supply of electricity for irrigation, the interest subvention on agricultural credit, and the premium subsidy for crop insurance. On the contrary, the recent trends show that 75% constitutes a higher number of electricity subsidies, reserved for agriculture consumers, from 2016-2019.

When a plant is unable to perform its functions normally, then it is diseased. The two major causes of disease in crops and trees are pathogens and environmental conditions. There are many kinds of disease pathogens: viruses, bacteria, fungi, nematodes, mycoplasma-like organisms, and parasitic higher plants. Fungal pathogens are the most common type. They cause seed rots, seedling damping-off, root rots, foliage diseases, cankers, vascular wilts, diebacks, galls and tumors, trunk rots, and decay of aging trees. Deterrents to establishment include unfavourable weather and environmental conditions such as Temperature and moisture extremes, high winds and ice may directly injure a tree and predispose the trees to pest attack.
Biodiversity plays multiple roles in development as well as ecological sustainability. It has received increased attention in agricultural ecosystems for the past few years regarding the reduction of plant diseases; however, the knowledge of using biodiversity to manage plant diseases is Still incomplete. For crop diversification, the interaction of genetic diversity per se in host populations with identifiable resistance and other functional traits of component genotypes to mitigate disease epidemics is not well understood, and neither is the best way of structuring mixed populations. The mixing of crop varieties can significantly reduce disease epidemics in the field. To achieve the best disease mitigation, growers should include as many varieties as possible in mixtures or, if only two component mixtures are possible. The many strategies, tactics, and techniques used in disease management can be grouped under very broad principles of action. The differences between these principles are often not clear. The simplest system consists of two principles, prevention (prophylaxis in some early writings) and therapy (treatment or cure). The first principle (prevention) has to do with disease management practices applied before infection-that is, the plant is protected from disease.

The term food processing covers an enormous field from simple boiling to the use of irradiation to predict the consequences on the nutritional value of fruits and vegetables. Generally, the food processing methods can be categorized as in intentional processing method (milling, peeling, washing trimming etc.), inevitable processing method (blanching, sterilizing, cooking, shredding, and drying) and accidental (inept processing or system). The nutritional losses associated with fruits and vegetable processing with different processing techniques and conditions employed. For example, the heavily processed products are although safe for human consumption but allied with reduced nutritive value. In this regard access to safe and nutritious food is considered as a basic right of humans as it is one of the ways to prevent various ailments by building better health and enforcing immunity. Escalating help awareness has guided the processes to opt for minimal processing food in recent years.
Food commodities subjected to minimal processing are capturing the market Suring to widespread concept that they might help in meeting the current requirement of vital nutrients. Development of minimally processed commodities especially fruits and vegetables have augmented at both retail and consumer levels during last years. Various organisations WHO, FAO, USDA boost up the utilization of minimally processed perishable commodities including vegetables and fruits to lessen the risk of cardiovascular diseases and cancer. Changes occurring in the eating habits have been quoted due to high anxiety for on time availability of these minimally processed fruits and vegetables. Sales of fresh cut fruits and vegetables continue to burgeon and food industries are persistently expanding primary because of consumers’ trend of health realization.

Botanically fruits are ripened ovary. It is a plant part that may or may not be purely derived from ovary of the flowers may be fleshy or pulpy in character, often juicy, predominantly sweet. With somewhat acidic taste, fragrance, aromatic flavours, fruits are generally not consumed during principal part of meals. Whereas vegetable is plant part which is less sweet, generally non acidic and consumed either cooked or raw during the principal part of our main meals. Vegetables may be fruit, root, stem flower, or leaf part of a plant or their modification.
Fruits and vegetables are valued in in human diet as an important source of protective nutrients like Minerals and vitamins. Apart from their nutritive value they add variety to the diet and improve acceptability of meal due to presence of different shades of colours, flavours, and texture. However, the major role in food preservation is played by their moisture content. For the same reason they are classified as
1. Perishable: Those which deteriorate quickly after harvesting such as tomatoes, mangoes, papaya, peaches, plums, juicy fruits and vegetables. They have high degree of moisture content and are highly susceptible to spoilage.
2. Semi perishable: These have less moisture content as compared to perishable one’s example 30 carrots, peace, green beans, apple etc. These foods are containing certain natural inhibitors to spoilage.

Minimal processing of fruits and vegetables
The technological development and modernization during recent years have resulted in in organisation coupled with Lifestyle modification and changes in dietary habits. This development and Organisation have made it easier to meet the requirement of processed food. Processing of fruits and vegetables effects shelf life providing ready to eat food with similarities to fresh product. Before the food Industries shoulder a bigger responsibility of utilising a novel technology to produce safe food without detrimental effects on quality. The industries need to who built biological (enzymatic / fomentation and biopreservation and Engineering solutions like non-thermal high-pressure treatment, cook chill, microencapsulation, vacuum impregnation etc. For the adoption of de - constructive culinary techniques such as 3D food printing and Molecular gastronomy as well as developments in nutrigenomics and digital technologies may facilitate novel product format, personalization, and access to niche market. Concretely, e - operating movement from Naresh mint to health improvement in present conditions demand or shift from defensive market oriented offensive market developing strategies including collaborative networks with Research Organization.
It is also defined as any fruit and vegetable that has been subjected to different processing steps (e.g. peeling, trimming, cutting, washing, disinfection rinsing etc.).

Pectin
Pectin is a component of nearly all fruits and vegetables and can be extracted and used in food processing to form the characteristic gel in jams and marmalade. The richest sources of pectin are the peels of citrus fruits such as lime, lemon, orange and passion fruit or the pulp of apple (known as ‘pomace’ after juice has been extracted). Commercially, pectin is available as either a light brown powder or as a dark liquid concentrate. It is stable if stored in cool, dry place and it will lose only about 2 per cent of its gelling power per year.
There are two main types of pectin:
• High methoxyl (HM) pectin that form gels in high solids jams (above 55% solids) in a pH range of 2.0-3.5; and
• Low methoxyl (LM) pectin, which do not need sugar or acid to form a gel, but instead use calcium salts.

Aromatic plants are the life line of essential oil trades all over the world. India is considered to be botanical garden on account of prevalence of rich plant biodiversity owing to varied topography and wide range of climatic conditions present in different parts of the country About 1300 plant species have been reported to be of aromatic value and 80 plant species are commercially grown and in high demand, but only 42 plant species
are being exploited by modern pharmaceutical and essential oil industries as a source of raw materials for a range of natural perfumes, flavours, cosmetics, food and flavouring and aroma–therapy.
Plant-genetic diversity is the key component of agricultural production system, and no natural evolutionary adjustment of the system to changing environment and biotic conditions would be possible without it. India is richly endowed with plant wealth, utilized either directly for cultivation or as source of useful traits for breeding improved varieties. Collection, conservation and sustainable use of available gene pool and their wild relatives require specific attention keeping in view their overall importance and significance in agriculture and food security vis-à-vis day–to-day needs.
Cultivation of aromatic plants having aroma due to presence of an essential
oil in their various parts needs to be made competitive against other seasonal crops, so that production from cultivated harvests are preferred over collections from the wild. There are possibilities of using the produce in cosmetic, perfumery and aromatherapy industries of several aromatic plants. So, the breeding strategy of aromatic crops should aim for improving the contents of therapeutic compounds, yield of grains, biomass yield, roots yield and oil quality & quantity.

The quality of essential oils is very complex. An individual oil may have hundreds of ingredients, the principle components being a group of complex substances known as terpenes and their compounds or derivatives. Due to this reason a single essence has a wide range of therapeutic actions.
The chemical constituents of plants are of two kinds: products of primary metabolism and products of secondary metabolism. The first are mainly carbohydrates, amino acids and fixed oils produced by light-absorbing (photosynthetic) processes. The latter group of chemicals arises from the primary metabolites. They include glycosides, terpenoids, alkaloid and essential oils. Essential oils lack the water soluble constituents such as tannins,
bitter compounds sugar, mucilages and pectins, playing important role in the medical action of the plant.
The essential oils have been credited with possessing almost all therapeutic properties in a concentrated form. The therapeutic properties of the whole oil are that result of synergism: an interaction of all its chemical constituents working harmoniously together so that the whole essential oil becomes more potent than the sum of its individual parts.
The essential oil lacks certain chemical compounds found in the raw plant material. It is still a highly complex substance, that it cannot be replicated in the laboratory. Even though high-tech processes such as gas liquid chromatography (GLC) can separate out main constituents of essential oils. By looking at the chromatogram, it is impossible to isolate the numerous trace elements including number of unidentified compounds which make up
the whole.

Introduction 
It is a common vegetable crop of rabi season which belongs to the family Apiaceae (Umbelliferae). Due to prevalence of protandry condition, the crop is cross pollinated in nature and self-pollination within individual flower is restricted. It comprised of three distinct cultivated varieties grown over the world for various economic purposes and classified as below depending upon usefulness of different parts.
Origin
It found is globally distributed in New Zealand, Australia, South Africa, Mediterranean basin, and South America, whereas Argentina and Chile are the richest sources. Habitat is extensively ranging from Egypt, Algeria, and Abyssinia to Sweden.

Introduction
Palmarosa/Roshagrass (Cymbopogon martinii var. motia): It is a tall perennial tuffed hedge grown naturally as well as commercially in the old world tropics and sub-tropics of India. It occurs in open scrub forests in parts of MP, Maharashtra and AP, where it is commercially collected and distilled for its oil. It is also sporadically found in Karnataka, TN and part of UP. The herb along with flowering tops and foliage, on distillation yield a colourless to pale yellow essential oil with sweet scented\ rose-like aroma, containing high geraniol; and used in cosmetics, toiletry and perfumery industry. Concerted efforts during last two decades to develop better cultural practices and development of improved varieties, the area has expanded all over the central, western and southern states of India. This crop is commercially grown in Indonesia, East African countries, Cuba and Brazil. At present, the total oil production is estimated to be around 300 tonnes annually, and two-third (200t) of it comes from cultivation.
Ginger grass (Cymbopogon martinii Stapf. var. sofia): This is another form of roshagrass. Its distribution is overlapping in forests with the ture palmarosa grass, although it has preference for more moist-substratum. Both the forms are morphologically identical in field except their odour when leaves are crushed. Ginger grass has dense tuft and more luxuriant growth, but produces shorter inflorescence and more tolerant to the stagnating water. It crosses freely with palmarosa in nature, producing many intermediary forms.

Introduction
Basil/Tulsi is a popular name given to any aromatic herb that belongs to genus Ocimum and family Lamiaceae (Labiatae). The word ‘basil’ was derived from Greek word ‘Basilica’ which means the royal plant. It comprises over 160 species spread over the tropical, sub-tropical, and warmer part of temperate regions of both the hemisphere ranging from sea level to 2000 m height with their diversity met in West Africa. Tropical Africa has maximum diversity with 59 species, followed by sub-tropical region of South Africa with 19 species and India with 9 species only.
 

Natural nutrient management in India marks a transition from synthetic fertilizers to sustainable, eco-friendly approaches that focus on improving soil fertility, crop yield, and environmental integrity. Rooted in traditional Indian agricultural wisdom, these practices are regaining importance due to their compatibility with natural farming principles, minimal reliance on external inputs, and enhancement of soil microbial activity.
A key method is the use of Jeevamrut, a fermented culture made using cow dung, cow urine, jaggery, pulse flour, and soil from field bunds. This mixture significantly boosts microbial activity in the soil, facilitating nutrient availability and decomposition of organic matter. It is applied directly to the soil or as a foliar spray and is known for improving nitrogen fixation and phosphorus release.
Ghanjeevamrut, a dry, solid variant of Jeevamrut, is used as a base application before sowing. It delivers a slow release of nutrients and is ideal for areas facing water shortages or crops requiring prolonged nourishment.
Panchagavya, another traditional bio-input, is a blend of five cow-derived products—milk, curd, ghee, urine, and dung—alongside banana, coconut water, jaggery, and water. Used mainly as a growth promoter, Panchagavya enhances germination, root development, and crop immunity, and is often applied as a foliar spray.
Green manuring using legumes such as sunhemp, dhaincha, and cowpea contributes significantly by adding organic nitrogen to the soil. These crops also improve soil aeration, structure, and moisture retention when incorporated into the soil.

Natural farming in India is witnessing growing acceptance, driven by concerns over environmental sustainability, soil health, and human well-being. To accelerate this transition away from chemical-intensive practices, both central and state governments, along with NGOs, have initiated comprehensive support systems that include policy frameworks, training, financial aid, and market facilitation.
A cornerstone of India’s natural farming policy is the Bharatiya Prakritik Krishi Paddhati (BPKP), launched under the Paramparagat Krishi Vikas Yojana (PKVY). This centrally sponsored scheme empowers states to implement natural farming by offering financial and technical assistance. States like Andhra Pradesh, Himachal Pradesh, Gujarat, and Maharashtra have led in adopting cluster-based natural farming models with large-scale training and demonstration programs.
Farmer training is central to adoption. Institutions such as Krishi Vigyan Kendras (KVKs), agricultural universities, and NGOs conduct extensive workshops on techniques like Jeevamrit, mulching, intercropping, and water conservation. Learning is made accessible through practical exposure, model farms, and local-language manuals, supported by digital tools like mobile advisories and community radio.
Support mechanisms include input subsidies for cow-based formulations, certification under Jaivik Bharat, and marketing linkages. Farmer Producer, Organizations (FPOs) facilitate input procurement, processing, and branding, while digital platforms improve market access and price realization.

(A) Enumeration of Microbial Growth by Turbidity Measurement
Method and Estimation of Generation Time
Introduction
Bacterial growth usually refers to reproduction-increase in population sizerather than to enlargement of mycelia cells. “Reproduction in bacteria occurs mainly through binary (binary means one cell becomes two) or transverse fission that results in the formation of two daughter cells. This is repeated at intervals by each new daughter cell in turn, or with each successive round of division. The population increases (Fig. 1). The time required for a complete fission cycle i.e. parent cell to two daughter cells is called the generation or doubling time. In bacteria, it is a doubling process in which each new fission cycle or generation increases the population by a factor of 2. So the parent stage consists of 2 cells, the second of 4, then 8, 16, 32, 64, 128, 256 and so on (Fig. 2). Thus the population will double, over and over again as long as the environment remains favorable for growth. The length of generation time is a measure of the growth rate of an organism. The average generation time in bacteria is 30-60 minutes under optimum conditions. Some species have very rapid growth rate and short generation time (5-10 minutes) and others have very slow growth rates and long generation times (measured in days). Staphylococcus aureus and Salmonella enteritidis, both causes of food poisoning, are examples of pathogens having relatively short doubling times of 20-30 minutes, which result in a few million cells from a few cells in a few hours in the infested food. The longest generation time occurs in species of Mycobacterium, particularly Mycobacterium leprae (the cause of leprosy) of 10-30 days as long as in some animals.

Ornamental horticulture is the branch of horticulture concerned with cultivating plants of all kinds for show and to satisfy the eye rather than for food (Bailey, 1960). It includes floriculture, the culture of trees for shades, display and landscape gardening. Gill (1988) defined taxonomy as a study aimed at producing a system of classification of biological organisms, which best reflects the totality of their similarities and differences. According to
him, there are three inter-related aspects of taxonomy namely: Identification, Nomenclature and Classification. Identification deals with the determination of a taxon as being identical or similar to another and already known organisms. Nomenclature on the other hand has to do with determination of the correct name for the organisms and is governed by International Code of Botanical Nomenclature. It permits only a single valid name for each plant. Classification is the placing of plants in groups or categories according to particular plan or system.
The objectives of taxonomy are to provide: a convenient method of identifying, naming and describing plants, a classification which as far as possible express the natural relationships of organisms, detect evolution at work, discovering its processes and interpreting its results, an inventory of plant resources-local, regional and continental and to provide an integrating and unifying role in the training of biology.

Collection and conservation of genetic resources in horticultural crops is very much essential in regions where local seed sources are still used in genetic enhancement and cultivar production. Domesticated crops grow well adapted to both tropical and temperate regions. In particular, if the crop is domesticated over centuries to be grown in different latitudes, the genetic diversity estimates are essential for a breeder to develop location specific cultivars. Genetic ulnerability, erosion and extinction of some wild progenitors and species has been altered, warranting the need for ex situ conservation measures. The material is conserved in various forms, ranging from botanical gardens, clonal and seed populations, vegetative methods, in vitro active repositories, pollen cryobanks and DNA banks. The objective, in genetic resource context, is to conserve for prolonged duration with minimal loss of viability and genetic diversity. Most ex situ conservation methods are technology dependent. Seed and pollen banks are dependent in refrigeration technology and cryogenic technology.
The conservation of plant genetic resources in ornamental species is generally driven by demand, focusing on preserving a wide range of genetic diversity. This diversity can include individual genes and coadapted gene complexes at the micro level, as well as entire genotypes, elite clones, and plant populationsat the macro level. The distribution of genetic diversity (GD) in plant species  is predominantly dependent on the reproductive mechanisms they adopt and the mode of inheritance of the characters targeted for collection. The main reasons for collection and conservation genetic resources of an ornamental species gene pool in a given ecosystem are:

It is represented by about 100 genera and over 2,200 species which are either annual or perennial, Caryophyllaceae are cosmopolitan in distribution, and mainly found in the north temperate or warm temperate regions of the world. Over 20 genera and about 100 species have so far been reported from India. Some of the larger genera, along with their common names and number of species in parenthesis include Silene (catchfly, 500), Dianthus (carnation, 300), Arenaria (sandwort, 250), Gypsophila (baby’s breath, 125), Stellaria (chickweed, 100), Cerastium (mouse-ear chickweed, 100), Drymaria (50), Spergula (40), Saponaria (30), etc.
Carnation, commonly named as ‘Divine flower’, ‘Clove pink’, and ‘Gilly flower’, is one of the most beautiful and commercially important flower crops of the world. It is excellent for cut flowers, bedding, pots, edging and rock gardens due to its exquisite shape, wide range of colours, light weight and good vase life. In Europe and USA, perpetual carnation is cultivated on large scale in greenhouses for production of cut flowers. In terrain parts of France and Holland, carnation flowers are used for perfume extraction and only light coloured flowers are useful for this purpose.
Description of Family
1. General habit: Mostly annual or perennial herbs, rarely suffrutescent shrubs; arctic forms are reduced and possess caespitose habit.
2. Stem: Herbaceous; rarely with a basal woody part; nodes swollen; branching usually dichotomous but sometimes monopodial.

A family of approximately 29 genera and 600 species, Oleaceae are cosmopolitan but occur in great diversity in temperature and tropical Asia. Some of the largely represented genera of olive family and their approximately
reported species are Jasminum (300), Chionanthus (125), Linociera (80), Fraxinus (70), Ligustrum (40), Syringa (30) and Olea (20).
Genus Jasminum contains 90 species to be true in existence and use, range from landscape to hair adornments, and perfumes. It is native to Indo-Malayan region. Morphological variants from different species have been developed in different regions in India. Jasmines are one of the most important ornamental flowering plants, widely cultivated for their attractive and fragrant flowers. Jasmine has multiple uses like in the making of bouquets, garlands, decorating women’s hair as veni, beautifying pandals and marriage halls and the like, besides preparation of perfumes and cosmetics. Jasminum grandiflorum is highly priced for high grade perfumes throughout the world. Jasmine oil has a significant place as an ingredient in cosmetics, confectionary, ointments, disinfectants and detergents and in pharmaceutical beverages. The word ‘jasmine’ has been derived from a Persian name ‘Yasmun’ meaning fragrance.

Orchidaceae is one of the largest families of the flowering plants, represented by about 1,000 genera and 20,000 species which are cosmopolitan but primarily distributed in tropical areas. They are found in all parts of the world, even in the frozen areas of Alaska, the snow-covered areas of the Himalayas and sandy deserts of Australia and Africa. New Guinea has more orchids, native to the island, than any other part of the world. In Indian flora, this is the second largest family having 7% of the world’s orchid genetic diversity contributing 1,330 species in 186 genera distributed mainly in Eastern Himalayas, Western Ghats and Khasi hills. Indian orchid wealth serves as a foundation of world’s orchid industry. The North-Eastern hilly regions of India, Himalayas being the cradle, comprises eight states- Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura- is the abode of unique orchids. Many are now endangered due to man’s invasion and “burn and grow” type of shifting cultivation. Arunachal Pradesh alone accounts for 601 species, almost 52% of the total species known in India. Arunachal’s rich and colourful orchids find a place of pride. Arunachal Pradesh is called the ‘Orchid Paradise of India’. The entire orchid family with about 601 species in Arunachal Pradesh is classified into six sub-families, 17 tribes, 24 sub-tribes and 111 genera. Vanda is found as epiphyte on mango and other trees in the plains. Aerides is found in southern and northern parts of India, Burma, Malaya and Indonesia, Vanda spp. is common in India, Sri Lanka, South East Asia and Indonesia. Calanthe spp. have a wide range from China, Japan, Vietnam to Australia, Southern parts of India and South Africa. The striking Cattleya spp. are found only in South America. Coelogyne, a genus of considerable horticultural value, is mostly represented in Nepal and Sikkim but several species are found in Bhutan and upper Myanmar, China, South-East Asia, the Philippines and Fiji. About 20% of recorded Indian taxa are endemic. Dendrobium peguanum is a rare species, Rhizanthella gardneri is endemic to Western Australia which grows underground and Phaius tankervilliae (Nun’s orchid of Assam; 2n= 50) is also an endangered orchid. India has two conservation and germplasm centers at Shillong in Meghalaya and Yercaud in Tamil Nadu. Asia’s largest orchidarium is situated at Tipi, Arunachal Pradesh while orchids sanctuary is situated at Sikkim.

A family of about 90 genera and 3,000 species distributed in both tropical and temperate regions. Central and South America are the chief centres of distribution where over 40 genera are found. About 15 genera and over 90
species have been reported from India. Some of the larger genera along with their approximately world over reported species (Hickey and King, 1988) are Solanum (1700), Cestrum (150), Physalis (100), Lycium (80-90), Nicotiana (66), Capsicum (50), Petunia (40), Hyoscyamus (20) and Datura (10). Solanum tuberosum (potato) and Nicotiana tabacum (tobacco) are the two most utilized plants of Solanaceae.
Petunias, popular bedding plants, with variety of forms, sizes and shapes are employed for landscape planning, garden designs and container gardening. The numerous phenotypes viz., Grandifloras, Multifloras, Millifloras, Waves, Hedgifloras, etc. are complex hybrids. The outstanding marketable series of P. x hybrida have been developed for upright, spreading and semi-trailing to trailing habits.
Selected Indian Genera

A family of about 86 genera and 3,000 species distributed chiefly in tropics and sub-tropics. About 22 genera and over 30 species have been reported from India. Some of the genera along with their number of approximately reported species and common names of them are Clerodendron (400, glory-flower), Verbena (250, vervain), Vitex (250, chaste tree), Lippia (220, Frogfruit), Lantana (150), Callicarpa (140, beauty-berry), Stachytarpheta (100) and Tectona (3, teak).
Verbena is popular ornamental plant suitable for flower gardens, hanging baskets, and balcony boxes. They are excellent both as ground cover for rockeries, and as bedding types. These plants abundantly flower in the seedin year and, thus, are grown as annual plants.
Selected Indian Genera
Clerodendron, Duranta, Lantana, Tectona, Verbena, Vitex.
Economic Importance
1. Timber yielding plants: Teak, one of the most famous timber-yielding plants of the world, belongs to Verbenaceae. It is used for high quality furnitures, heavy constructions, ship building, musical instruments and several other similar purposes. Some other timber-yielding plants are Gmelina arborea, Premna benghalensis and Vitex altissima.

DUS testing is a way of determining whether a newly bred variety differs from existing varieties within the same species, or the characteristics used to establish distinctness are expressed uniformly and that these characteristics do not change over subsequent generations. Testing the distinctness, uniformity and stability (DUS) of crop varieties is a statutory requirement before varieties can be entered into the Registers of Cultivars (National Lists) and/or granted Plant Breeders’ Rights (PBR). In India, Protection of Plant Varieties and Farmers’ Right (PPV&FR) Act (2001) provides the registration of new variety of plant if it conforms to the criteria of distinctness, uniformity and stability.
Why do we need a DUS test? New (candidate) varieties should be distinct from all other varieties whose existence is a matter of common knowledge, and also sufficiently uniform and stable with respect to the characteristics used to demonstrate distinctness. ‘Common knowledge’ is broadly defined to include all known varieties, i.e. any variety entered into or subject to an application for PBR, varieties grown commercially, held in publicly accessible reference collection, or of which there is a published description (UPOV 2002).
The responsibility for DUS testing of potato varieties in India lies with the ICAR-Central Potato Research Institute (CPRI), Shimla, which is the national institute for potato research and development. Currently a set of 51 DUS characters in potato are defined by CPRI and being used for distinguishing new variety.

Fruits contribute to nutritional security and thus are an important part of food system. To meet the future demand, development of varieties with improved yield and quality is the focus of researchers involved in fruit breeding. Though conventional breeding has resulted in the development of improved commercial varieties of different fruit crops, however conventional breeding is time consuming and faces several challenges due to long juvenile phase, highly heterozygous nature of most of the fruit crops. Challenges like changing climate, consumer preference, socio-economic conditions like reduced availability of land, labour and increasing cost of inputs, require fast and efficient methods to develop the varieties to meet the demands, which is not feasible with conventional breeding. Marker assisted breeding has given impetus to breeding efforts in several fruit crops, however it’s use is limited only for the traits controlled by a few major QTLs.
During last few years, enormous genomic resources have been developed for fruit crops using next generation sequencing technology. Such advances in genomic research in many fruit crops have paved the way for precision breeding using genomic assisted breeding (GAB) tools. GAB has helped in characterisation and utilisation of genome resources and using allele variation for cultivar development (Varshney et al. 2021). Advances in sequencing technology and affordability has allowed the genome wide analysis (GWAS) on diversity panels of different fruits resulting in identification of allelic variation associated with the traits of interest. Also, identification of superior alleles of candidate genes makes them amenable to genome editing based precision breeding. Genome wide genotyping and phenotyping offers tools for developing strategy for genomic selection (GS). Genomic selection relies on the prediction of breeding values of tested genotypes based on the large number of markers spread over entire genome. These tools promise to further improve breeding efficiency in fruit crops.

Introduction
Food preservation refers to an art or science which deals with the process of prevention of decay, deterioration or spoilage of food commodity to allow it to be stored in a safe condition for future use. All foods gradually undergo deterioration or spoilage from the time immediately they are harvested or manufactured. Some commodities spoil rapidly, while others can keep longer but for limited periods. The basic purposes of food preservation are:
1. Extension of shelf life of foods thus increasing the supply
2. Ensuring the availability of seasonal foods throughout the year
3. Adding variety to the diet
4. Saving time by reducing preparation time and energy
5. Stabilizing farm prices and prices of food
6. Improving the nutritional qualities The food spoilage can be caused due to growth and activity of micro-organisms, insects or rodents, action of enzymes, chemical reactions and physical changes that takes place during processing, drying, or freezing etc. Classification of Food Depending upon the type of spoilage and level of perishability, the foods are classified into three broad categories:

Introduction: Food processing involves different steps from receiving raw material, preparing for product manufacture, and packaging to storage. All these steps are called unit operations. They are broadly categorized as raw
material preparation (receiving, sorting, grading, washing, peeling, blanching, slicing, cutting, dicing etc), processing (canning, drying, pulping, juicing, product manufacture like jam, jelly, preserves, candies, pickling, sauce making, etc.) and post-production handling including packaging and storage. A brief detail about each unit operation is discussed as under:
1. Raw Material Handling
Material handling includes varied operations such as hand or mechanical harvesting on the farm, transportation in trucks or refrigerated vehicles of perishable produce to the market or to the processing plant or to store/godowns. For conveying, a wide variety of mechanical conveyors is used depending on the type of material. Common conveyors used in the processing plant include screw conveyors, bucket conveyors, belt conveyors and vibratory conveyors. Throughout these operations, care is taken to maintain sanitary conditions, minimize bruises and product loss, maintain raw material quality like physical appearance, and vitamin contents, minimize microbial growth and minimize other detrimental changes to the product quality during handling etc. It also includes other unit operations like receiving, cleaning/washing, sorting, grading, peeling, halving, slicing, blanching etc for preparation of fruit and vegetables for processing.

History of plant breeding
The process of plant breeding takes care of changing or modifying the genetically controlled characters of a particular variety or genotype of a crop. The practice of age-old agriculture uses the process of selection from the existing variability to save a particular quality of seed to grow better crops in the next harvest.
Gregor Mendel who is known as the father of Genetics discovered the law of segregation in the middle of the 1800s. This theory forms the base for the process of plant breeding. The primitive ways used for plant breeding are very different than what modern technology has contributed to the process of plant breeding during the 20th century.
Plant breeding is the science and art of purposeful manipulation of characters of crop species to create new varieties with a set of desired characteristics. Significance of plant breeding has been highlighted especially after the “Green Revolution”.

The term genome refers to a complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In the nucleus of each cell, the DNA molecule is packaged into thread like structures called chromosomes and each species has specific chromosome number. Most of the plants are diploid and they show in each one of its body cell, twice the number of haploid chromosomes (n) found in the gametes.
There are two main types of chromosomal variation that involve changes in the number. These are euploidy (in Greek “eu”means true or even and “ploid”means unit), which involves the variation of whole sets of chromosomes and aneuploidy(“aneu” means uneven), where a single chromosome within a set varies. This variation may be either increase or decrease in the chromosome number. The euploids include diploid (2n), triploid (3n), tetraploid (4n), hexaploid (6n) or even higher degree of polyploidy. Polyploidy, thus involves more than two genomes and is, therefore, a genometic mutation involving increase in the dose of whole genome. This condition of polyploidy is more common in angiosperms.

Bottle gourd, Lagenaria siceraria under the family Cucurbitaceae (Chromosome No: 2n = 2× = 22) is commonly grown vegetable crop of India, Africa, Central America and other warmer regions of the world. Tender fruits are widely used as cooked vegetables in a number of ways. Bottle gourd is a good source of vitamin C and zinc that may offer several skin benefits. It also contains minerals like calcium, magnesium, iron, and zinc. Its dietary fibre enhances gastro-intestinal health and promotes bowel movements and prevents constipation.
Origin, domestication and adaptation in India
It is the only crop known to have been cultivated in pre-Columbian times in both the Old and New World. Bottle gourd is indigenous to the tropical Africa. It has
bihemispheric distribution in Africa, the old world and America, the new World. Its utilization by man is about 16,000 years in the Old World and 12,000 years in the New World. It was independently domesticated in the two hemispheres. It was one of the world’s first cultivated plants grown not primarily for food, but for the use of hardshelled fruit as containers. The apparent wild plant produces thinner-walled fruit that, when dried, would not endure the rigors of use on long journeys as a water container. Today’s bottle gourd may owe it’s tough, waterproof wall to selection pressures over its long history of domestication. The bottle gourd was theorized to have drifted across the Atlantic Ocean from Africa to South America.

Crucifers, also known as Brassicas or cole crops, are a group of vegetables belonging to the family Brassicaceae (formerly Cruciferae). Common cruciferous vegetables include cabbage, cauliflower, broccoli, kale, mustard, turnip, and radish. These crops are widely grown around the world due to their nutritional value, economic importance, and adaptability to diverse climates.
However, crucifers are highly susceptible to a wide range of insect pests that can cause significant yield losses if not managed properly. These pests attack various parts of the plant, including leaves, stems, roots, and heads, leading to both quantitative and qualitative damage.
Distribution
Crocidolomia binotalis is widely distributed in India and is particularly prevalent in regions where cruciferous vegetables are cultivated. The pest is active from the third week of November to the fourth week of December, with varying population densities depending on environmental conditions (Pawar et al., 2010)

Distribution
Thrips tabaci is present in the central and southern regions of India, occupying about 36.4% of the land area under the current climate conditions. In central India, the states of Maharashtra, Karnataka, Madhya Pradesh, Gujarat, and parts of Rajasthan offer highly suitable habitats. In the northern region, areas such as Uttar Pradesh, Bihar, Jharkhand, Chhattisgarh, Delhi, Haryana, Punjab, Uttarakhand, & parts of the northeastern states are favorable. In southern India, Karnataka, Andhra Pradesh, Telangana, & Tamil Nadu are particularly suitable.
Biology Adults: Adult onion thrips overwinter in soil in onion, small grain, and hay fields. More mobile than immature stages, adults can fly and are attracted to white and yellow colours, often landing on clothing or skin. They are elongated, with body colour ranging from yellow to brown, and have pale, fringed wings. Adults measure 1.0–1.3 mm for females and 0.7 mm for males. Their lifespan is 16–42 days on garlic and 28–30 days on onion. Females lay eggs for up to three weeks after a one-week preoviposition period. In spring, adults emerge, colonize weed hosts, & can fly or be carried by wind to new plants.
Eggs
Females lay eggs individually in leaf tissue, with one end near the surface for immatures to emerge. The eggs are microscopic, kidney-shaped, and initially white or yellow, turning orange with reddish eye spots as they mature. On onion, eggs average 0.23 mm in length and 0.08 mm in width. The incubation period is 4–5 days on onion, with hatching occurring in 2–3 days in the lab, but 5–10 days in cooler field conditions.

Chilli (Capsicum annuum L.), a member of the Solanaceae, is a significant spice and vegetable crop in India, extensively cultivated over warm temperate, tropical, and subtropical regions. Approximately 51 insect pests and two mite species from 27 families and 9 orders were discovered to be infesting chillies (Reddy and Puttaswamy, 1983). The yield losses range from 50-90 per cent due to insect pests in chilli (Nelson and Natrajan, 1994)
Chilli thrips: Scirtothrips dorsalis, Thripidae, Thysanoptera Biology
The adults are slender, yellowish brown in colour, with long, narrow, and heavily fringed wings. The adult female inserts eggs into the tissues of the leaves and shoots. The nymphs are similar to adults, except they are smaller and wingless. With the exception of the rainy season, the pest is present all year round. The life cycle is completed over a period of two weeks. Over the course of a year, multiple generations overlap.
Recently introduced invasive thrips in chilly is Thrips parvispinus Karny. It causes premature flower drop, shedding of fruits and malformations resulting in severe yield loss. The average fecundity is about 56 eggs with a mean developmental period of 18.8 days (Muray et al., 2009).
