[目的]分析云南主栽甘蓝型油菜品种间遗传距离与杂种优势的相关性。[方法]利用 SSR分子标记技术对云南8个主栽甘蓝型油菜品种间的遗传距离进行分析，并探讨其与田间表现的杂种优势的相关性。[结果]杂交亲本间遗传距离与杂种优势存在一定的相关性，但并不显著。[结论]分子标记技术用于油菜杂种优势预测从而筛选亲本存在一定的困难。

Objective] The correlation between genetic distance and heterosis of the major Brassica napus L. cultivars in Yunnan Province was analyzed. [Method] The genetic distances among the 8 major Brassica napus L. cultivars in Yunnan Province were investigated with the SSR molecular marker technique. Moreover, the correlation between genetic distance and field appearance of heterosis was ana-lyzed. [Result] There was a certain correlation between the genetic distance and heterosis of crossing parents (P>0.05). [Conclusion] It is difficult to predict the het-erosis of Brassica napus L. cultivars and to screen parents by using the SSR molecular marker technique.
