Abstract The combining ability and genetic effects of 4 quality characters in tomato Di D4 taken as female were analyzed by way of Griffing constant parent regression analysis with 10 inbred lines and 9 crossing combinations as experimental material. The results showed that variance percents of general combining ability on fruit weight and fruit hardness were 80.00 %，93.74 %, respectively；variance percents of general combining ability and special combining ability on total acid and soluble solids content were 53.85 %，54.76 % and 46.15 %，44.26 %, respectively. The broad heredity of soluble solids content，fruit weight, fruit hardness and total acid reached 0.765 0，0.750 0，0.649 3 and 0.928 5, respectively. However, narrow heredity was 0.737 1，0.532 9，0.631 5 and 0.527 3, respectively. Only the correlation coefficients of fruit weight reached significant level.
