摘　　要：对河南省113份地方茶树种质资源的主要表型性状进行了遗传多样性分析.结果表明:河南省地方茶树种质资源的表型性状具有丰富变异和多样性,12个描述型性状的平均遗传多样性指数(H')为0.97,叶色的遗传多样性指数最大,叶身的变异程度最高;各表型性状间存在一定的相关性,叶长与叶面积的相关性最高,相关性系数为0.85.基于12个表型性状,利用聚类分析将113份种质资源分为4个类群.基于叶面积、叶形、叶色等性状的差异,将113份河南地方种质资源分为31个类型.Diversity analysis of phenotypic characteristics for 113 Henan local teas germplasm resources.The results showed that the phenotypic characteristics of Henan local tea germplasm resources were rich in variation and diversity.The average diversity index(H′)of 12 descriptive characteristics were 0.97,the highest was leaf color and character of leaf level,respectively.There were significant correlations among those phenotypic characteristics.The biggest correlation coefficient was 0.85 between the leaf length and the leaf area.The 113 germplasm resources were clustered into 4 groups by using cluster analysis based on those 12 descriptive characteristics.According to the leaf area,leaf shape and leaf color,the 113 Henan local tea germplasm resources were divided into 31 types.
