Abstract: The genetic diversity among 34 Chinese oilseed accessions ( mainly from Hunan and Hubei Provinces) of B . rapa was analyzed by RAPD technique and statistical methods. A general molecular method for assessment of genetic diversity was established from this research. Cluster analysis showed that the genetic variation among oilseed accessions of B . rapa was closely related with their eco-geographic distribution ; extensive variation existed among the accessions from Hunan and Hubei Provinces ; 34 accessions were divided into eight groups at DNA level. The application of results to selection of parents in breeding program was discussed.
