摘　　要：利用 2 4个随机引物对山羊草属 12个二倍体物种的亲缘关系进行了RAPD分析 ,对扩增出的 30 4条带进行聚类分析。结果发现 :(1)Sitopsis组内各物种的亲缘关系与前人的研究基本一致 ;(2 )Ae .mutica与Comopyrum组的各物种亲缘关系较近 ;(3)Ae.uniaristata与同组的另两个物种亲缘关系较远 ,应将其从该组中独立出来 ;(4)Ae.caudata与Ae.RAPD analysis was performed by a set of 24 arbitrary primers to 12 diploid species in Aegilops . Results were observed based on the examination of 304 RAPD fragments. The relationship in the Section Sitopsis is consistent with the former investigation. Ae. mutica had a relatively close relationship with the species of the Section Comopyrum. Ae. uniaristata had a far relationship with the other two species of the Section Comopyrum,indicating that it should be excluded from this section. Ae. caudata and Ae. umbellulata had a close relationship.
