Relates how the pool of plant genetic resources provides vital raw material for producing new and improved crops, and serves as source material for experimental biologists. The first four sections provide a detailed survey of the role of plants, guidance on the size and structure of plant collections, and, finally, the principles and strategies for evaluation. The last two sections look at wild relatives of crops and the impact of new technology. The volume will be of great use to plant breeders, crop scientists, conservationists and plant biologists. "...a useful reference serving as a 'snapshot' of current concepts and activities in a reemerging area of interest to the scientific community. Its modest price also makes it accessible to a broad range of interested parties." Economic Botany "...the book is interesting, and presents information well regarding the conservation of plant biodiversity from the gene to species level. We recommend the book to those interested in crops and their relatives." Valeria C. Volin and John C. Volin, Economic Botany This 1989 volume stresses the way in which the pool of plant genetic resources provides vital raw material for producing new and improved crops. Used Book in Good Condition
