| 摘 要： | 本文利用ＲＡＰＤ方法和统计学分析，对我国７省市和国外引进的总计４０份甘蓝型油菜品种的遗传多样性进行了研究。结果表明，４０个品种的甘蓝型油菜存在着广泛的遗传变异，根据ＲＡＰＤ指纹图谱，通过在ＤＮＡ分子水平上的聚类分析可以将它们分为３大类群，反映出这些品种之间的亲缘关系，并对如何引进甘蓝型油菜资源进行了初浅的讨论。

| Abstract: | 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. |
