摘　　要：利用AFLP技术对30个牡丹品种的遗传多样性进行了研究。用3对引物组合进行选择性扩增,共产生151个位点,其中96个为多态性位点,占63.5%。其中2个受试品种产生了特异性位点。聚类分析结果显示,遗传距离0.25将30个牡丹品种划分为5个聚类组,与传统分类结果基本一致。AFLP analysis was applied to study the genetic relationship among 30 Paeonia suffruticosa cultivars. 3 pairs of primer combination were screened from 30 pairs of primer combination and generated 151 bands, 96 of which were polymorphic bands （63.5%）. There are two cultivars which generated special DNA fragments. Cluster analysis showed that 30 cultivars were divided into 5 cluster groups with a genetic distance of 0. 25. The result is generally consistent with the traditional classified.
