This book will serve as a comprehensive sourcebook for individuals involved in the production of quality assured seed. It will be useful to researchers, students, and others in the field, and will include information on all types of crop plants, whether they are propagated through seeds or clones. The book will also cover advancements in seed technology, such as in vitro clones, micropropagation, artificial/synthetic seeds, and organic seeds, as well as genetics, breeding, and molecular breeding perspectives related to the production of nucleus and breeder seeds in annual and perennial crops, including grain, legume, pulse, fiber, oil, vegetable, fruit, and other horticultural crops.
