Abstract

This paper reviews the use of world germplasm resources after nearly a century of collecting and preserving crop genetic diversity. Germplasm banks and seed collections that serve as repositories of genetic variation have been established as a source of genes for improving agricultural crops. Genetic linkage maps have made it possible to study the chromosomal locations of genes for improving yield and other complex traits important to agriculture. The exploitation of rice and tomato using molecular linkage maps combined with advanced backcross QTL (quantitative trait loci) methods are given as examples of a gene-based approach to screening exotic germplasm. Molecular tools of genome research may finally release the genetic potential of wild and cultivated germplasm resources
