The genetic diversity among 34 Chinese oilseed accessions ( mainly from Hunan and Hubei Provinces) of B . rapa was analyzed by RAPD technique and statistical met hods. A general molecular met hod for assessment of genetic diversity was established from t his research. Cluster analysis showed t hat t he genetic variation among oilseed accessions of B . rapa was closely related wit h t heir eco2geograp hic distribution ; exten2 sive variation existed among t he accessions from Hunan and Hubei
