Abstract: 30 hybrid combinations were combined from 6 high inbred parents (42, 43, 44, 50, 63, 69) of many years according to Griffing complete dealer cross design (p2). The general combining ability and special combining ability of 5 main fruit characters (lycopene, soluble solid, weight, fruit shape index, sugar-acid ratio)of tomato were analyzed with 6 inbreds and 30 hybrids, in order to provide theoretical basis for the breeding of new varieties and improve main quality characters of tomato. The results showed that, parents of 43 lycopene, sugar-acid ratio, soluble solid of character of general combining ability effect the highest value or higher, explain 43 was a breeding flavor and nutrition varieties in terms of the quality of the ideal parent material. Parents of 42 weight of the general combining ability effect was the highest value, 42 can cultivate good quality as the appearance of tomato ideal material. Combination 50×43 in the quality traits of the special ability were relatively high, it can be used as a breeding excellent characters comprehensive comparative good varieties.
