Rice germplasm resources in Guizhou are rich in genetic diversity with relatively large variation of biological characters and various types from evolution and artificial selection.Being evaluated and sorted systematically and comprehensively with the multi-disciplinary sciences,5168 traditional varieties,collected from 79 counties of Guizhou,accounting for about 10% of the total in China,were regenerated and sent to the National Bank of Crops Germplasm Resources at Chinese Academy of Agricultural Sciences (CAAS)for long-term storage.There were some elite types including semi-dwarf, big panicle,big grain,high quality,cold and drought tolerance,resistance to diseases and pests.Other special elite types characterized by restoring to CMS,wide compatibility,and poly-embryonic seedlings were also screened out.Database for base and core collection was established to facilitate the uhilization of rice germplasm resources.
