Contribution of wild Crucifers in Brassica improvement: past accomplishment and future perspectives

摘要：

Brassica related wild germplasm Brassica coenospecies is a potential source of many useful nuclesr genes for enriching conventional germplasm, and cytoplasmic genes for inducing male sterility. Intensive hybridization between wild and crop species representing interspecific, intergeneric and intertribal combinations have accumulated vast information on genome homoeology.Biotechnological tools have made possible to circumvent even the tribal boundaries. Genes of interest have been introgressed frm wild germplasm to crop species which include resistance to beet cyst nematode, altemaria blight and black leg. A number of alloplasmics of crop species have been synthesized combining wild cytoplasms for expression of male sterility. Wild germplasm is to be systematically characterized for various traits.
