Seed Technology And Seed Pathology

The Book Is Comprehensive And Provides Up-To Date Information Relating To Recent Areas Of Research In Seed Technology And Seed Pathology In The Indian Perspective. It Is Divided Into Four Sections: 1. Seed Physiology, Quality And Seed Production, 2. Seed Storage, Bio-Deterioration And Mycotoxins, 3. Seed-Borne Microflora And Diseases And 4. Management Of Seed Borne Diseases.

This Fourth Edition of Principles of Seed Science and Technology, like the fIrst three editions, is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology of seeds. The fIrst nine chapters present the seed as a biological system and cover its origin, development, composition, function (and sometimes nonfunction), performance and ultimate deterioration. The last nine chapters present the fundamentals of how seeds are produced, conditioned, evaluated and distributed in our modern agricultural society. Two new chapters have been added in this fourth edition, one on seed ecology and the second on seed drying. Finally, revisions have been made throughout to reflect changes that have occurred in the seed industry since publication of the Third Edition. Because of the fundamental importance of seeds to both agriculture and to all of society, we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will be communicated to our readers. Furthermore, we have attempted to present information in a straight-forward, easy-ta-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology.

It is the II edition of the book entitled Seed Technology published in the year 2000. The revised edition also provides comprehensive and integrated information for the courses offered by traditional universities in the background of agriculture. The book includes line diagrams and flow charts extensively to make it practical oriented. Features: • Basics of seed and variety • Seed production system • Maintenance breeding • Production of hybrids, seedless varieties, tubers, TPS and synthetic seed • Post harvest seed management • Seed storage • Certification of seed production programme at field level • Testing of seed in laboratory • Verification of genetic purity including molecular approaches • Seed and seedling vigour testing • Seed health and its certification • Value addition • Seed commerce • Seed law enforcement • Acts, rules and bills on seed • Protection of plant variety and DUS testing • Export of seed • Indian seed certification standards with revision and edition

The development of an improved agriculture is an indispensable step towards better living standards. It depends upon improved inputs of which seed is the most significant. Seed has always been regarded as the most vital, basic and critical input. Sage Parashara (circa 400 BC) had said, "the origin of plentiful yield is the seed". Today, more than two millennia later, the statement holds true and it will be hold true as long as humans inhabit the earth. Seed health is a priority area in seed production programme. In recent years, the awareness for seed health has increased among the growers, traders, consumers and policy makers. In post -GATT era and with the emergence of WTO concerns regarding the seed health have acquired high importance. In seed production programme, seed certification standards have been worked out. Several diseases have been designated objectionable at field and seed levels. The book provides comprehensive and integrated information on 57 seed-borne diseases covering about 40 major field and vegetable crops. The information is supplemented with about 127 photographs, explanation of technical words in glossary and further readings. The book will be of great help to the people engaged in seed production (fields and vegetable crops), seed certification, agricultural extension workers, field workers and seed industry. It will be of immense use for all the teachers, students and researchers of seed science and technology. Feature: sRole of seed-borne pathogens. Significance of seed health testing. Seed health testing for seed-borne fungal, bacterial, viral and nematode pathogens. Protocols for some common methods employed in seed health testing. Integrated management of seed-borne diseases. Indian seed certification standards for Field and Vegetable crops. Identification and management of objectionable seed-borne diseases. Information on pathogens, location in seeds, disease-cycle and spread, nature, losses, detection techniques and certification standards of 57 seed-borne diseases, supplemented with 127 black and white photographs. Explanation of about 160 technical words in glossary.

This Third Edition of Principles of Seed Science and Technology. like the first two editions. is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology ofseeds. The first eight chapters presentthe seed as abiologicalsystemand coverits origin. development. composition. function (and sometimes nonfunctionJ, performance and ultimate deterioration. The last seven chapters present the fundamentals ofhow seedsare produced. conditioned. evaluated and distributed in our modern agricultural society. A new chapter on seed enhancement has been added to reflect the significant advancements made in the last 10 years on new physiological and molecular biology techniques to further enhance seed performance. Because of the fundamental importance of seeds to both agriculture and to all of society. we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will becommuni cated to our readers. Furthermore. we have attempted to present information in a straight-forward. easy-to-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology. . We believe this Third Edition represents a new level in presenting information that appeals to advanced undergraduate students as well as to those desiring more fundamental information on seed form and function. At the same time. it continues to havethestrengths ofthe firsttwoeditions.initsreadabilityaswellas itscomprehensive coverage of the broader area of seed science and technology.

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.
