This book aims to provide a comprehensive understanding of seed biology, the latest advancements in breeding techniques, and the technological innovations that enhance seed quality and performance. It addresses the challenges faced by seed producers, including climate change, pest resistance, and the need for sustainable practices, while highlighting solutions and strategies that ensure robust seed systems.
Readers will gain insights into traditional and modern seed production methods, the role of biotechnology and genetic engineering, and the importance of regulatory frameworks in maintaining seed quality. The book also discusses the economic and social impacts of seed technology, emphasizing the importance of collaboration between scientists, farmers, and policymakers.
Seed Production and Technology is designed for students, researchers, practitioners, and anyone with a keen interest in agriculture and food security. It serves as a valuable resource for understanding how high-quality seeds are developed, produced, and brought to market, ultimately contributing to the global effort to feed an ever-growing population sustainably.
Seeds are the foundation of agriculture, representing the beginning of the food production chain and the cornerstone of food security worldwide. "Seed Production and Technology" delves into the intricacies of this critical sector, exploring the science, innovations, and best practices that drive the production of high-quality seeds.

Previous Year Questions 1. What is seed treatment? 2. Factors affecting the seed quality of a crop during seed production? 3. Seed treatment campaign – Role & importance? 4. Agronomic and genetic principles of quality seed production? 5. Varietal seed production and hybrid seed production? Seed Treatment Seed treatment refers to the application of fungicide, insecticide or both to the seeds to disinfect(deep seated) and disinfest (over seed coat) them from seed borne or soil borne pathogenic organisms and storage insects. It also refers to subjecting the seed to solar energy exposure or immersion in conditional water.
Previous Year Questions 1. Different Classes of Seeds? 2. Various parameters of field & seed standards for breeder seed production? 3. Factors that affect the longevity of seeds during storage in warehouses? 4. Initial Seed Quality? 5. Seed Testing? Different Classes of Seeds 1. Nucleus Seed: It is handful of seed maintained by concerned breeder for further multiplication. The nucleus seed will have all the characters that the breeder has placed in it and it is of highest genetic purity. The quantity of nucleus seed is in kilograms. 2. Breeder Seed (BS): Breeder seed is a seed or vegetative propagating material directly controlled by the originating or sponsoring plant breeder of the breeding programme or institution and or seed whose production is personally supervised by a qualified plant breeder and which provides the source for the initial and recurring increase of foundation seed. Breeder seed is exempted from certification. However, the breeder seed crop is being inspected at appropriate stages by a Monitoring Team consisting of breeder, representative of NSC and representative of Seed Certification Agency. The breeder seed lots are affixed with Golden Yellow tags. The genetic purity of breeder seed crop should be maintained at 100 per cent.
Previous Year Questions 1. What is DNA fingerprinting? Discuss the applied aspects in modern agriculture. (15M, CSE 2021) • The term DNA fingerprinting in its original sense refers to the method developed in 1985 by Sir Alec Jeffreys (Jeffreys et al., 1985) and his associates for the simultaneous detection of highly variable DNA fragments by hybridisation of specific multilocus probes to electrophoretically separated restriction fragments? • The DNA fingerprints, resembling barcodes, are unique to the individual and hence can be used in much the same way as conventional fingerprints - to identify individuals with absolute certainty? DNA Fingerprinting Techniques • A large number of fingerprinting techniques are in currency, which are variations and combinations of restriction fragmentation and polymerase chain reaction (PCR). • Restriction fragment length polymorphism (RFLP) involves digesting DNA with restriction enzymes, separating the resultant DNA fragments by gel electrophoresis, blotting the fragments to a filter and hybridising probes to the separated fragments. Specific probe-enzyme combinations give highly reproducible patterns. • With the advent of PCR technology a number of simpler techniques have become available for molecular characterisation. • These include, random amplified polymorphic DNA (RAPD) and its several variants, intersimple sequence repeats (ISSR), amplified fragment length polymorphism (AFLP) and sequence tagged microsatellites sites (STMS).
Previous year questions 1. Introduction? 2. Role of private? Introduction • The Indian seed industry used to be dominated by public sector seed companies. However, following the easing of government regulations and the implementation of a new seed policy in 1988, the private sector seed companies have started playing a major role in seed development and marketing. • More recently, the government’s decision to embrace biotechnology as a means of achieving food security has attracted several leading biotechnology-focused multinational seed companies to India. • The composition of the seed industry, by volume of turnover, has reportedly reached a ratio of 60:40 between the private and public sectors.
Previous Year Questions 1. Intellectual property rights (IPR) are the rights given to persons over the creations of their minds: inventions, literary and artistic works, and symbols, names and images used in commerce. They usually give the creator an exclusive right over the use of his/her creation for a certain period of time? 2. Plant varietal protection? • The importance of intellectual property was first recognized in the Paris Convention for the Protection of Industrial Property (1883) and the Berne Convention for the Protection of Literary and Artistic Works (1886). Both treaties are administered by the World Intellectual Property Organization (WIPO).
