Abstract:: Taking 5 varieties tomatos as materials to make 10 reciprocal cross hybrid combinations，content of soluble solid，Vitamin C，oganic acid of tomato were studied，in order to provide reference to tomato advance combination.The results showed that the content of vitamin C of ‘JL-1×Xiaohong’ was significant different with that of ‘Xiaohong×JL-1’，the vitamin C content of ‘JL-1×Xiaohong’ was 150.61% higher than the ‘Xiaohong×JL-1’，organic acid content and sugar content was 60.53%，8.42% higher than ‘Xiaohong×JL-1’.The quality of anti-cross combination of ‘Xiaohong×Qianxi’ and ‘Qianxi×Xiaohong’ were better than their corresponding orthogonal combination，there were not significant differences in yield，the combination of ‘JL-1×Xiaohong’，‘Xiaohong×Qianxi’ and ‘815×Xiaohong’ was suitable for the promotion and application.Orthogonal combination of ‘815×Qianxi’ and reverse cross combination of ‘Qianxi×815’ had significant difference in sugar content，‘Qianxi×815’ was 25.43% higher sugar content than ‘815×Qianxi’，‘Qianxi×815 ’were more sweetness.All the traits of Reciprocal crosses ‘Qianxi×Xiaohong’ and ‘Xiaohong×Qianxi’，the ‘16 Green×Xiaohong’ and ‘Xiaohong×16 Green’ had no significant differences，indicating that the nucleus of genetic was dominant，the effects of cytoplasmic were not obvious．
