This book focuses on the previously neglected interface between the conservation of plant genetic resources and their utilization. Only through utilization can the potential value of conserved genetic resources be realized. However, as this book shows, much conserved germplasm has to be subjected to long-term pre-breeding and genetic enhancement before it can be used in plant breeding programs.The authors explore the rationale and approaches for such pre-breeding efforts as the basis for broadening the genetic bases of crop production. Examples from a range of major food crops are presented and issues analyzed by leading authorities from around the world.

Based on twenty years of global research, this is the first comprehensive reference on crop genetic diversity as it is maintained on farmland around the world. Showcasing the findings of seven experts representing the fields of ecology, crop breeding, genetics, anthropology, economics, and policy, this invaluable resource places farmer-managed crop biodiversity squarely in the center of the science needed to feed the world and restore health to our productive landscapes. It will prove to be an essential tool in the training of agricultural and environmental scientists seeking the solutions necessary to ensure healthy, resilient ecosystems for future generations.
