Genes, Crops and the Environment [Paperback]

This book describes the genetic resources of plants, their management and conservation.The genetic combinations found in plants are the basis for plant breeding programs essential to the security of our present and future food supply. This book explains what these genetic resources are, how they are handled, and why they should be safely conserved.The genetic combinations found in plants are the basis for plant breeding programs essential to the security of our present and future food supply.

This book explains what these genetic resources are, how they are handled, and why they should be safely conserved for the future. The authors also explore the applications of this research to political and operational programs in all parts of the world and its impact on the conservation of biodiversity, ecosystem rehabilitation, and the future health of our planet.1. Plant genetic resources - what they are and why they are needed; 2. What needs to be collected and how is it maintained?; 3. A global strategy for safe storage; 4. Access to the resource - core collections and databases; 5. Have we all that we need for the future?; 6. Have genetic resources already been of value?; 7. When there are no seeds; 8. Genes and politics; 9. A glimpse from 2050; Index. Holden and colleagues trace the evolution of major crop plants, their migration from centers of origin, and their subsequent adaptation through plant breeding to a wider variety of environmental areas....The authors consider the need for worldwide collaboration and conservation of genetic materials, outline gaps in the science, and suggest urgently needed research....interesting book for the general public, undergraduates, graduates, and policymakers lãq
