Abstract: In order to simplify the indices for evaluating fruit quality without losing the information embodied in the original indices, 13 fruit quality indices including single fruit weight, fruit shape index, edible rate, total soluble solid content, titratable acid content, total sugar content, vitamin C etc. for 22 different wampee germplasm were analyzed by using multivariate statistics. Results of principal component analysis with the above 13 indices indicated that the cumulative proportion of former 3 principal components reach 84.8951%. By using systematic cluster analysis with eigenvectors of the former 3 principal component, 5 evaluation factors for a comprehensive system were obtained, and the single fruit weight, fruit shape index, titratable acid, total sugar, fruit sugar acid ratio were selected as simplified indices. The cluster analysis of fruit quality in wampee by this 5 selected indices showed that the fruit quality from 22 different germplasm resources could be clustered into 3 groups according to their euclidean distance of 2.07, which were the same with that of their sensory evaluation.
