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.

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.

Dramatic examples of genetic enhancement of seed quality exist relative to hardness, germination, protein quality and quantity, oil, and many other traits. Maintenance of seed quality is also paramount in the preservation of biodiversity. Readers first learn fundamentals of preserving and enhancing good agronomic seed quality as well as specific disease and deteoriation mechanisms. Succeeding chapters review applied breeding programs and explore specific crops and their seed quality traits.

This toolkit – made available in English, French and Spanish – will be promoted as practical guidance to assist in the implementation of the national seed strategies. It will provide a number of practical capacity building tools for essential stages of the seed value chain and targeted primarily at seed sector practitioners who will participate in special training workshops to acquire pertinent technical knowledge and will be expected in return to create a multiplier effect through further follow-up FFS trainings down to the level of seed traders and farmers. In doing so, the toolkit will be used as guidance for conducting country-led workshops and other training activities aimed at strengthening quality seed delivery systems and seed regulatory mechanisms in selected countries. The development of capacity in the production of high quality seeds, the seed replacement rates, true seed cost and realistic seed pricing mechanisms as well as the role of different stakeholders are of critical importance in the process of the formulation of national seed policies, which is one of the core areas of FAO’s delivery at the national level.

The quality declared seed system, as set out in the FAO Plant Production and Production Paper No. 117 (1993, ISBN 9251032785) has been widely used, particularly by those working in the field of emergency seed supply and as a source of practical information on seed standards for a range of crop species. The system provided an alternative for seed quality assurance, which was less demanding than full seed quality control systems. This publication sets out a revised version, prepared by an expert consultation, which offers a more explicit recognition of the role of national policies and the impact of some recent international obligations on seed provision and a clearer explanation on how quality declared seeds can accommodate local varieties. The list of crops now includes 92 species, of which 21 include open pollinated and hybrids and one includes also a synthetic variety. In making this update, FAO sought to improve seed supplies to farmers and thus to contribute to food security.

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.
