The genetic diversity and the relationship among 40 cultivars of  Brassica napus  from seven Provinces of China and other countries  Brassica napus  was analyzed by RAPD technique and statistical methods. Cluster analysis showed that the extensive genetic variation existed among 40 cultivars of B. napus. The 40 cultivars were divided into three groups at DNA level. This result has significance for the genetic breeding of Brassica napus.
