Abstract:: Four fresh tomato varieties were used as experimental materials,14 agronomic traits of tomato were determined，the relations between tomato agronomic traits and yield were analyzed.Using correlation analysis，grey correlation and multiple regression analysis method，the relationship between tomato agronomic traits and the relationship with the tomato yield were studied，to provide reference for screening of tomato varieties.The results showed that，the tomato production were very significant positive correlation with the average fruit number of per plant，the correlation coefficient was 0.994 2**，yield and plant height，flower festival a longitudinal diameter，average fruit number，fruit number and fruit shape index，the average individual results showed no significant positive correlation；grey correlation analysis showed that the correlation between the various characteristics and yield of tomato were width>growth period>fruit soluble solid content>fruit number per average>plant height>flower festival in the beginning a ventricular number>pulp thickness average number>average results showed the fruit yield and longitudinal diameter>stem diameter>fruit shape index.Multiple linear regression showed that affect tomato yield traits and yield was the average number of results.Conclusion was the average number of results was the key to affect the output of tomato yield and properties.
