Abstract: Lycopersicon esculentum is rich in nutrition and has become one of the most popular vegetable in China. In this paper，the yield component and fruit quality of five different tomato cultivars were compared. Under the same cultivation conditions，the writer analyzed the yield component per plant including fruit mass，branch number per plant，fruit number per branch，fruit number per plant and so on，the results indicated that the highest yield was T-3-2，followed by T-28，T-29-1 and red cherry，T-3-1 was the lowest；comparison of the size，the color，the soluble solids of ripe fruit，the appearance and other commodity quality suggested that the green T-3-1 have the best flavor，followed by yellow T-3-2，the difference was not statistically significant between them，but significantly higher than that of dull-red red cherry，bright yellow T-29-1 and red T-28. Field experiment and laboratory analysis showed that the yellow T-3-2 had high yield and good flavor，its comprehensive traits are significantly better than those of the other four cultivars，so the pilot demonstration can be carried out for this cultivar.

Key words: Lycopersicon esculentum, yield per plant, quality；soluble solids
