摘　　要： 利用RAPD技术对来自国内外的45份苦瓜栽培品种进行了亲缘关系分析。实验采用UPGMA方法进行聚类分析,并在此基础上建立分子系统树。实验结果将45个苦瓜品种分成滑身苦瓜和麻点苦瓜2大类,滑身苦瓜又可以分为来源于东南亚和来源于国内的2组,麻点苦瓜也可分为来源于中国香港和来源于中国内地的2组,说明苦瓜品种存在一定的地域性差异,另外亲缘关系上相近的品种也聚类到一起。 RAPD (random amplified polymorphic DNA) analysis was employed in order to detect genetic relationship in 45 balsam pear (Momordica charantia L.) cultivars. Based on UPGMA cluster analysis, a DNA molecular dendrogram was established. The results showed that: 45 balsam pear cultivars were divided into striped protuberance and granular (thorny) protuberance two types. Striped protuberance type was included two groups which respectively came from Southeastern Asia and China. Granular protuberance type was included two groups too which respectively came from Hongkong (China) and China mainland, which showing region difference. Besides, cultivars which be close on genetic relationship could be gathered.
