To explore the phenotypic diversity of A. crenata germplasm resources， 32 phenotypic traits of 56 A. crenata germplasm resources were analyzed using variance analysis， correlation analysis， principal component analysis， and cluster analysis. Diversity analyses showed that 56 A. crenata germplasm had enriched variation， with the Shannon-Wiener indices of 18 qualitative traits varying from 0.300 to 1.247， with a mean value of 0.734， and 14 quantitative traits with Shannon-Wiener indices ranging from 1.931 to 2.071， with a mean value of 2.007， and coefficients of variation 8.98%-46.32%， mean value 23.3%. The results of the correlation analysis showed that fruit transverse and longitudinal diameters had the highest correlation， fruit skin color was highly significantly positively correlated with fruiting branch total axis color， fruiting branch sub-axis color， fruit stalk color，and internode length was highly significantly positive correlated with plant height， current year trunk height. Principal component analysis indicated that eight principal components with a cumulative contribution of 76.34%， mainly plant and fruiting branch length， fruit and leaf color， were the main factors for phenotypic differences in A. crenata germplasm； four excellent germplasm resources of A. crenata with high composite scores were obtained by screening. Cluster analysis could classify the 56 A. crenata germplasm into six taxa， and there were large differences in phenotypic traits among different taxa. The abundant phenotypic diversity and varietal types provide a basis for the selection， development， and utilization of superior germplasm resources of A. crenata.
