Abstract: In order to create high quality and disease-resistant cherry tomato resources and provide parent materials for the subsequent breeding of new varieties,factor analysis was used to analyze the variables influencing tomato quality,such as total soluble solid (TSS),total acid,TSS-acid ratio, L* value, a* value, b* value,lycopene,pulp thickness,hardness,etc.,to evaluate 2 kinds of medium fruit species and 7 kinds of cherry tomato species. And field traits of 7 kinds of cherry tomato species were discribed,disease resistant genes were detected as well. In terms of quality and agronomic traits,except for cherry No. 29 F2-1-1,the cherry tomato resources bred by the laboratory were superior to the middle-fruit varieties and the high quality cultivar Yunü. Among them,Cherry No. 25 F2-1-1,Cherry No. 55 483-11-8,and Cherry No. 55 483-16-15 Yunü ranked better with common advantages of high TSS(with the value of 8.04%,8.13% and 7.59%,respectively),an excellent balance of sour and sweetness(with the TSS-acid ratio of 11.9,12.0 and 12.8,respectively),bright skin (with the L* value of 43.70,40.29 and 34.48,respectively),indeterminate growth type,early-medium maturity and being not easy to crack.In terms of disease resistance,Cherry No. 25 F2-1-1 both contained Tomato yellow leaf curl virus disease resistant genes Ty-3 (only having the genetic band of 641 bp) and root-knot nematode resistant gene Mi-1.2 (only having the genetic band of 550 bp),while Cherry No. 55 483-11-8 and Cherry No. 55 483-16-15 simultaneously contained Tomato yellow leaf curl virus disease resistant genes Ty-1 (only having the genetic band of 984 bp) and root-knot nematode resistant gene Mi-1.2 (only having the genetic band of 550 bp). So the three resources could be used as important parent materials of breeding high quality and disease resistance varieties as they were comprehensively evaluated as the best ones among all being investigated.
