选取37个形态学性状对33个丹参品系进行了数量分类学的聚类分析。结果表明：通过性状聚类分析，可将丹参37个性状划分为8类，各类内性状间具有一定相关性。主成分分析表明，37个性状可综合为9个主成分，其累积贡献率达72．777％。根据性状聚类分析和主成分分析的结果，初步提出丹参的分类体系以叶片大小为第一级分类标准，分枝数作为第二级标准，花色和复叶数分别作为第三级、第四级分类标准。通过Mantel相关性检测筛选出18个性状可较好代表37个性状进行种质聚类。

Based on the survey of S.miltiorrhiza germplasm resources,the numerical taxonomy method was used for cluster analysis of 33 cultivars with 37 morphological characters.The results revealed that 37 characters could be divided into 8 groups and those belonging to the same group had certain correlations.Prin-cipal component analysis showed that the 37 characters could be consolidated into 9 principal components and their accumulative contribution ratio reached 72.777%.According to the results of cluster analysis and princi-pal component analysis,a classification system of S.miltiorrhiza was preliminarily proposed with leaf size as the first criterion,the branch number,flower color and leaflet number as the second,third and forth criterion respectively.By Mantel correlation detection,18 characters,which could well represent 37 characters,were chosen for germplasm clustering of S.miltiorrhiza.
