An essential reference for students, seed technologists, researchers, and seed industry personnel, this comprehensive guide outlines the most widely performed modern seed quality tests, explores the principles behind them, the history of seed testing, why seeds are tested and when, and sampling, sub-sampling, seed laboratory management, accreditation, and seed quality assurance programs. The authors describe statistical applications to seed testing and tolerances, and they provide a detailed morphological and structural description of seed formation and development. The book examines the testing of genetic traits and transgenic seeds, including DNA and protein genetic purity tests, and cultivar purity identification for conventional seeds. In addition to the most common seed purity and viability tests, tests for seed and seedling vigor, seed-borne diseases and seed moisture determination are also discussed.

This practical guide covers the commonly used detection methods for seed-transmitted viruses and viroids that affect both tropical and temperate crops. It contains 25 complete step-by-step procedures for biological, serological and molecular techniques to detect and identify such viruses. Combining helpful practical notes with more detailed explanations of the principles behind the techniques, the book describes the general characteristics of seed-transmitted viral diseases and discusses outlines for the organization and interpretation of seed health assays. The techniques reviewed are also applicable to non-seed-transmitted viral agents.

Seed Purity and Taxonomy replaces The Handbook of Seed Testing, as the most complete and up-to-date resource of information available on seed identification and seed taxonomy. Seed Purity and Taxonomy contains a comprehensive listing of seeds along with approximately 3,000 black-and-white sketches, photographs, and computer-scanned images of species most likely to be encountered in seed testing laboratories in North America. Internal morphological features of different family groups are also included. These images are complemented with detailed descriptions and numerous dichotomous keys that will help in making definitive identifications.

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.

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.
