Assessment Of The Requirements Of High Yielding Seeds And The Development Of The Seed Industry

Overview of the seed industry in developing countries; An analytical framework; Government policies; Conclusions and priorities for future research.

Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.

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.

Seeds are the vehicle for delivering the improvements in a crop to the farmer’s field. They are therefore a critical input in agricultural production. Seeds are also unique in that they must remain alive and healthy when they are used and that they are also the input that farmers can produce by themselves. Module 4 Seed Sector Regulatory Framework provides information on the elements of the regulations that govern the seed value chain – from variety registration through quality seed production to distribution and marketing. The materials covered include information about national seed policy, seed law and regulations, their definitions, purpose and interactions.

Revised and expanded throughout, this latest edition of the bestselling Seeds Handbook: Biology, Production, Processing, and Storage includes valuable information on all areas of seed biology, production, and processing. The author, one of the most respected and prolific scientists in the field, identifies current developments in seed testing and certification, storage, transportation, and distribution. Tracking the evolution and advancement of seed industries and technologies, he fully covers the development and supply of high-quality seeds for every key agronomic and horticulture crop. Contains methods to enhance the genetic and physiological characteristics of more than 80 major and minor crops With an abundance of current research and additional figures and illustrations, this edition of the Seeds Handbook offers chapters on modern biotechnological issues such as the production of synthetic seeds, loss-reduction biotechnologies, and new strategies in the seed production industry. It provides in-depth information on burgeoning areas of seed science including tissue culture and cellular totipotency, induction and regeneration protocols, development and maturation, hormone requirements, drying and storage of somatic embryos, protective encapsulation, and crop applications. With an eye to the future, it looks at challenges in the provision and enhancement of seeds for crop plants, practical methods of seed production and micropropagation, genetically modified seeds, and world food security.

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.

High-quality seed is essential for healthy crops and greater agricultural productivity. At the same time, advances in breeding technology require equivalent advances in seed technology. In order to ensure food security, it is crucial to develop seeds that are high yielding, and resistant to drought, heat, cold, and insects. Gathering the latest research in seed sciences, the book includes contributions on seed production in crops such as legumes, sugar, rice, wheat and other cereals. It discusses a range of topics, like the effect of climate change on seed quality, production and storage; seed rouging; seed certification for different crop species; seed biology; and seed pathologies and their effective management. Integrating basic and applied research, this compendium provides valuable insights for researchers and students in agricultural and life sciences; professionals involved in seed certification and those working in quarantine laboratories; as well as plant pathologists.
