Sixty-six kiwifruit germplasm resources were used,and 19 phenotypic traits of branches,leaves and fruits were observed,and factor analysis and cluster analysis were applied to analyze the variation coefficient of distribution frequency of phenotypic traits of these kiwifruit germplasm resources. The results showed:the average variation of the 10 characters was 4.9,and the most abundant one was fruit shape(9),among the nine quantitative traits,the coefficient of variation of stalk length was the largest (41.04%),and that for fruit longitudinal diameter was the smallest(12.14%). Q cluster analysis divided the 66 kiwifruit resources into four groups,and the germplasm resources in the same groups were clustered by color of one-year-old twig,mass of single fruit and fruit shape index,etc.

Key words: kiwifruit, germplasm resources, phenotype, diversity
