Abstract: In order to build fruit quality evaluation system for Actinidia eriantha, we used DPSS software to perform the principal component analysis (PCA) of the quality indexes on A. eriantha, such as soluble sugar, titratable acid, vitamin C, soluble solid and so on. The results showed that the variable coefficient of the fruit had significant difference, and the variable coefficient of soluble sugar was the largest (41.34%). Principal component analysis showed that six quality indicators were integrated into three principal component factors, which could represent 82.629% of the amount of information of A. eriantha fruit quality. Comprehensive evaluation of the results showed that the fruit qualities of the samples No.59, 13, 14, 12, 55, 4, 60, 15, 57, 25, 58 were excellent, and that of the samples No. 41, 45, 53, 34, 20, 21, 22, 32 were poorer. Analyzing the quality of the collected A. eriantha fruits, this study found out three principal components of the comprehensive evaluation of fruit quality of A. eriantha, and revealed the diversity of the fruit quality of different A. eriantha.
