摘要/Abstract

摘要： Variation evaluation，genetic correlation analysis and principal component analysis were carried out by 13 qualitative and 16 quantitative traits to study the genetic diversity of 353 tomato germplasm resources. The results showed that the genetic diversity of phenotypic traits was rich in these tomato germplasms. In qualitative traits，the highest Shannon-Wiener diversity index was growth vigor （1.50）. In quantitative traits，the highest genetic diversity indexes were leaf length（2.07）and leaf width （2.07），and the highest coefficient variation（CV）was the fruit cracking rate（73.08%）. There was a complex relationship among these traits. The cumulative contribution rate of the first 9 principal components was 64.83%，which contains most information of all indicators. The 353 tomato resources were divided into 6 groups at the genetic distance of 17.5 by means of systematic clustering and inter group aggregation. The group V contained 138 resources mainly characterized by round fruit shape and limited growth habit. Group VI contained 203 resources mainly characterized by small single fruit weight and unlimited growth habit.
