摘　　要：对原产于中国的果梅种质资源首先根据传统的分类方法分为白梅类、青梅类和红梅类3组,然后每组分别根据种质的形态特征及农艺性状等27个基本数据和特征数据进行聚类分析和排序,并参考同工酶、RAPD和SSR分子检测结果,从197个果梅品种和优株中筛选出核心种质20份,并对核心种质的代表性进行了检验。结果表明,构建的核心种质能够代表果梅原种质的遗传变异。Cluster analysis was used to study the relationship of Japanese apricot originated from China. First, three groups were classified according to the color of the fruits: group for white mei, red mei and green mei. Then, clustered according to 27 characteristics with SAS program. The data of isozyme, RAPD and SSR were also taken into account. Finally, 20 Japanese apricot germplasms were screened as core collection from 197 Japanese apricot germplasms. The reliability of core collection was identified.
