The management of rice genetic resources

Abstract

Rice growers and researchers are endowed with an enormously rich germ plasm of pantropical distribution, mostly conserved before serious genetic erosion sets in. Efficient management of the conserved resources and effective use of the diverse gene pools justify arduous and costly investments in conservation. A sound conservation system requires adequate field space for seed increase and rejuvenation, cost-efficient and secure storage facilities, a database management system, availability of conserved materials and related information to users, and vigilant monitoring of seed viability. Linkage with evaluators, breeders, and biotechnologists is essential for full use of the conserved materials. Periodic consultation with specialists will extend a collection's usefulness, through further collection or re-collection of germ plasm and in situ conservation, compatibility of documentation systems, and enhanced interinstitutional and international collaboration. Training of germ-plasm workers should be part of the management system. The continuity in human resources will provide security, their dedication will ensure service, interdisciplinary communication will promote use. Improving the capability of national genebanks augments the security of collections preserved at duplicate sites. Gene-bank management must be sustained by adequate administrative and financial support. An effective public information program will further ensure support and security.Key words: rice, Oryza sativa, genetic resources, genetic conservation, gene-bank management.
