摘要
利用RAPD技术对41份洋葱种质资源的遗传多样性进行了分析。从100个随机引物中筛选出7个引物，共扩增出64．个位点，其中多态性位点34个（53．13％）。材料间遗传相似系数变化范围为0.694～1．000。在遗传相似系数为0．926水平上，聚类分析结果可将供试材料分为9类，聚类结果与形态学特征有一定对应关系。
The genetic diversity of 41 onion （AUium cepa L. ） germplasm resources were analyzed by RAPD （Random Amplified Polymorphic DNA）. Results showed that 34 （53.13%） polymorphic sites were detected among the total 64 sites amplified by 7 screened random primers （ among 100 primers）. The RAPD- based genetic similarity ranged from 0. 694 to 1. 000. UPGMA cluster analysis showed that the tested materials could be divided into nine groups at the level of genetic similarity 0. 926. Dendrogram obtained using molecular markers is homologous with separated morphologic character in some degree.
