Seed Quality

Seed Quality: Basic Mechanisms and Agricultural Implications focuses on various aspects of seed quality and integrates research at basic and applied levels, supporting high-quality seeds as the basis of higher agricultural productivity. With its clear perspective and interdisciplinary focus on basic and applied aspects of seed quality, this book is immensely useful to students and teachers in many agricultural and botanical disciplines. Because seed quality is a critical component in the economic considerations of the farmer and the seedman alike, Basra looks in-depth at these aspects of seed production: seed viability seed health seed vigor seed testing variety identification crop yield seed storage seed production seed deterioration seed treatments Seed quality is of international agronomic concern, and the recent upsurge of interest in seed quality has accentuated a new awareness regarding its importance in crop production. This book meets the need for information and could form the basis of long-range planning by policymakers on quality assurance and management programs and in the facilitation of international trade. Researchers, students, and teachers in many agricultural and botanical disciplines--seed science and technology in particular--will find this book to be of immense use. It can be used as a handbook for those involved in seed industry and seed testing services. It is recommended for international courses in seed science and technology and seed training programs.

Seed is the source of future plants or foods, is the storage place of culture of history, is the first link in the food chain, is the ultimate symbol of food security. Seed is the source of life. Seeds are basic in crop production. No agricultural practice can improve a crop beyond the limits set by the seed. Quality seed is the key for successful agriculture, which demands each and every seed should be readily germinable and produce a vigorous seedling ensuring high yield. “Care with the seed and joy with the harvest” and “Good seed doesn’t cost it always pays” are the popular adage which enlightens the importance of the quality seed. The farmers always very much interested in the best seed management practices which are safe, environmentally sound and scientifically proven technologies. Understandably, in view of the importance of quality seeds in Agriculture, both as a product and as a means of establishing a crop, most attention at all levels of investigation has been directed to crop seeds. Since seed is a biological entity, deterioration beyond harvest is inevitable. The consequences of low quality seeds are poor germination, low and delayed emergence and weak growth leading to poor field stand and ultimately reflecting on reduced yield. Low productivity could be attributed broadly to use of poor quality seeds. At present to overcome this, several seed enhancement techniques are available for quality upgradation. It has two goals; one is related to seed designing and other to seed functioning. The rationale for pre-sowing seed enhancement techniques is to mobilize the seeds own resources and to augment them with external resources to get maximum improvement in field stand establishment and yield. To achieve this, several physical, physiological and biochemical treatments are available at present to give value addition to seeds. Physiological seed treatments that improve seed performance are based primarily on seed hydration and dehydration. Among several non physiological seed treatments, coating or pelleting can also indirectly improve seed germination, stand establishment and crop productivity.

The book is about the seed development in the model and crop plants. Seed development is a key step of the plant life cycle that determines the nutrient value of seeds – the life for human civilization, growth, and development. The nutrient value of seeds is mainly due to storage reserve products such as carbohydrates, lipids (triacylglycerols), and proteins. The book primarily focuses on application of the 21st century high-throughput technologies transcriptomics, proteomics, metabolomics, and systems biology in near complete understanding of the various processes involved in seed development in different crop plants. The book reveals how such technologies have revolutionized our understanding of the multilayer processes and regulations involved therein by generating large-scale datasets. Accumulated datasets provide basic knowledge to develop integrated strategies to eventually improve the nutritional value of plant seed and crop yield, a critical goal in food security issues around the globe.

This open-access edited book is a collection of 17 chapters, synthesized primarily from the lectures delivered by eminent Indian and international experts during a series of capacity-building programmes organised in India during 2020 and 2021 under the aegis of 'Indo-German Cooperation on Seed Sector Development', a component of the Bilateral Cooperation between the Governments of India and Germany. Seed Science and Technology, a multi-disciplinary subject, is advancing rapidly keeping pace with the development of improved plant varieties and other climate-resilient technologies. Knowledge of the underlying biological processes and application of appropriate technologies for variety maintenance and seed production; quality assurance, testing and enhancement; processing, packaging and storage etc., are important in a seed programme. Chapters presented in the book is a blend of basic seed biology covering seed development, maturation, dormancy, germination, vigour and invigoration, and seed deterioration; variety maintenance and production of genetically pure seed of open-pollinated and hybrid varieties in a few key field crops and vegetables, and fundamentals of seed processing, packaging and storage; and seed quality assurance systems followed in different countries; testing the essential components of seed quality including seed health, application of molecular technologies for precision in testing, and enhancement of seed quality. It concludes by identifying the key areas of future seed research and technology development. The book covers the fundamentals and recent advances of seed science and technology with the latest research information and an exhaustive and updated list of references on different topics. It is expected to benefit the students as well as the scientists, faculty members and seed sector professionals, working in the public and private seed sectors, certification authorities and seed producing agencies in India, and elsewhere.
