双季茭白品种资源材料的系统聚类分析

HIERACHICAL CLUSTERING ANALYSIS OF DOUBLE SEASON WATER BAMBOO GERMPLASM RESOURCES

用系统聚类分析中常用的６种方法对２４份双季茭白品种资源材料进行分类，有５种方法分类的结果一致而类平均法的结果最佳。２４份材料被分成３类，第１类以苏州地方品种资源材料为代表，第２类以无锡地方品种资源材料为代表，第３类彼此之间的相似程度较低、肉质茎较小、商品性较差。

24 double season water bamboo (Zizania caduciflora Turcz. HandMazz) varieties are numerically classified by 6 methods of hierachical clustering analysis. The average linkage method is the most appropriate. The varieties are classified into three types; The first type is represented by the Suzhou local varieties, the second type is represented by the Wuxi local varieties and the third type has small fleshy stems with poor commercial quality and shares less similarity between each other. The results of hierachial clustering analysis are similar to the those kof the horticulture classification.
