摘要
对柚子36个品种13个花部性状进行测定,并用SPSS软件进行分析。结果表明,柚子花部外部性状的变异性大于内部性状;花内部性状之间的相关性大于其与外部性状之间的相关性;从Q聚类图可知,柚子可基本聚为4类,且种间杂种柚的欧氏距离远大于其他品种;花部性状的R型聚类分析显示,有两组性状的欧氏距离较近,可以将其分别聚为两个性状。
13 flower features of 36 pomelo eultivars were measured and the data were analyzed using SPSS in this paper. The results showed that： （1）The variability of external feature of flower was larger than that of internal feature. （2）The eoIrelation between the internal features of flower was more significant than the external＇ .（3）36 pomelo eultivars were classified into four groups according to Qmluster analysis, the euclidean distance among interspecifie hybrids pomelo euhivars among the breeds was futher than other pomelo cultivars. （4）The euclidean distance of two groups flower feature was nearer than others based on R-cluster, thus they could be combined into two features.
