| 摘 要： | 该试验选取28个分类性状，应用近年来发展起来的数量分类学原理与方法对沂州海棠11个样本进行了初步研究。结果表明，应用数学方法对沂州海棠进行品种分类研究是可行的。Q型聚类分析结果反映了各品种之间的亲缘及演化关系。R型聚类分析表明，性状的选取是正确的，各个分类性状之间没有明显的逻辑关系，对品种的演化具有较独立的意义。

| Abstract: | In this paper,11 cultivars and 28 characters of Chaenomeles'Yizhou' were preliminary studied by numerical taxonomy methods,which developed in the recent years.The result showed that it was feasible to classify the cultivars of Chaenomeles'Yizhou'.The Q cluster analysis reflected the genetic relationship of all cultivars.According to the R cluster analysis ,the selection of the testing characters was almost correct,all the characters had no obvious logical relationship with one another and had indipendent effect on the cultivar evolution. |
