This Joint ISTA and FAO Handbook provides comprehensive guidelines for the setting up and managing of seed testing laboratories, including those that cater to small- and medium-scale seed enterprises and farmers’ cooperatives, which operate in low input production systems. The adherence to the guidelines by seed testing laboratories results in the use of uniform procedures across the board thereby facilitating inter-laboratory transferability of data. This harmonization enhances confidence in seed quality assurance mechanisms. The publication is an update of a previous one that was also jointly published by both organizations in 1969 and revised in 1979 and 1983. Its utility is enhanced by a set of new up-to-date information that builds upon existing data. The Handbook provides guidance on the range of seed testing equipment, procedures, and management systems that have become available in the several decades since the previous editions. Seed testing is a critical component of the seed value chain and is essential for the production of quality seeds, i.e. seeds that are alive, can germinate and produce vigorous seedlings; are healthy and come from lots that meet set thresholds for genetic and analytical purity. The Handbook covers all aspects of seed testing, from laboratory design and equipment selection to sample preparation, testing methods, and data analysis. Importantly, the publication also addresses the challenges of testing seeds in low input systems and provides guidance on how to adapt procedures to these settings. Therefore, it serves as a reference material and training resource for everyone involved in seed quality assurance procedures, in particular the personnel of seed testing laboratories and regulatory agencies; seed producers and farmers. The updated publication represents a significant improvement over previous guidelines, as it incorporates advances in technology and provides guidance on a broader range of testing procedures. The guidelines are designed to be adaptable to different contexts and seed types and include recommendations for quality management systems, proficiency testing, and inter-laboratory comparisons, which are essential for ensuring the accuracy and reliability of seed testing results.

Preface In agricultural sciences, the materials of most common interest are soils, plants, irrigation water and seeds. Chemical methods of analysis are needed to test these materials to know their compositions, characteristics and to give necessary recommendations. There was a long felt need to provide a comprehensive practical manual on soil, plant, water and seed testing for the graduate and post graduate students, scientists and technicians working on this aspect.

Seed Biology: Insects, and Seed Collection, Storage, Testing, and Certification, Volume III brings together a large body of important information on seed biology. The book describes seed collection, identification, storage, testing, and certification. It also considers insects that directly affect seeds, seed-producing organs, or seed-bearing structures of plants. Organized into six chapters, this volume begins by outlining man's dependency on seeds as source of food, fiber, spices, beverages, oils, vitamins, and drugs. Harmful effects of seeds are also mentioned. Separate chapters focus on seed development, dissemination, germination (including metabolism, environmental control, internal control, dormancy, and seed and seedling vigor), protection from diseases and insects, longevity, and deterioration. The book concludes with a discussion on the certification of field and tree seeds, the Organization for Economic Cooperation and Development certification schemes, and trends in seed certification. This book is a valuable source of information for seed producers and users as well as various groups of research biologists and teachers, including agronomists, plant anatomists, biochemists, ecologists, entomologists, foresters, horticulturists, plant pathologists, and plant physiologists.

Seed testing centers exist in almost every country in every corner of the globe. More and more students are enrolling in programs that require knowledge of the complex and fascinating science of seed pathology. The implications of seed pathology for human health remains an important issue. For all of these reasons and more, this book is a necessary and timely reference that covers the full range of related topics, including techniques for detecting and studying microorganisms associated with seeds, their epidemiology, and control. No other book like this exists. Until now, the information has been widely scattered in journals and other sources. This is an excellent new edition - ideal for students and teachers in the agricultural and life sciences; individuals involved in seed certification; members of plant quarantine laboratories; plant pathologists doing research in seed pathology; and producers of planting seeds for the next season's crops.
