摘　　要：利用SPSS软件对柚类20个品种的19个叶片性状进行了Q型聚类及其R型聚类,结果表明,20个柚品种可分为4个组群;19个性状可以分为3个组群。试验结果与其他学者的分类结果相补充,为今后更好的利用形态学指标评定柚类品种及根据分类结果来丰富育种材料提供了更多的依据。Q cluster analysis and R cluster analysis have been used to examine the 19 leaf characteristics from the 20 pumelo cultivars with SPSS software. The results show that the 20 pumelo cultivars could be divided into four groups, and the 19 characteristics could be divided into three groups. The result is supplied mutually with others＇ research, and provides us with better support in taking advantage of various characters to evaluate pumelo cultivars or in widening the breeding varieties according to different target.
