Abstract:
Taking 60 cherry tomato varieties as materials，their principal component and cluster analysis of germplasm quality traits were analyzed by using SPSS software.The results showed that 12 traits were classified into 5 principal components and their additive contributing rate came up to 80.234%; 60 cherry tomato varieties were divided into 8 categories through cluster analysis，and there was a wide genetic distance and quality between each category.The results could provide the basis for evaluation of tomato main quality traits the quality breeding.
