Abstract: 【Objective】 To explore the relationship between lycopene and related traits of processing tomato fruit, and to provide theoretical basis for processing tomato breeding in Xinjiang. 【Methods】 The varieties (lines) selected or introduced in recent years were used as 30 experimental materials, the correlation between lycopene content and soluble solid content, mean pulp thickness, pH value, a/b value, beta-carotene and L value was studied, and meanwhile, stepwise regression analysis and path analysis were performed. 【Results】 The results showed that the contents of soluble solids, average flesh thickness, pH value, a/b value, Beta-carotene and L value of 7 fruits of Xinjiang processing tomato varieties (lines) were correlated, there was a significant positive correlation between pH value and L value, a significant positive correlation between lycopene and a/b value, a significant negative correlation between lycopene and L value, a significant negative correlation between lycopene and L value, a significant positive correlation between lycopene and L value, a significant negative correlation between lycopene and L value, a significant positive correlation between lycopene and L value, a significant positive correlation between lycopene and L value, a significant positive correlation between lycopene and L value, a significant negative correlation between lycopene, but the correlation was not significant. There was a significant positive correlation between a/b value and lycopene, and a significant negative correlation between a/b value and beta-carotene and L value. The beta-carotene was positively correlated with L value, negatively correlated with X₅ and negatively correlated with lycopene, but the correlation was not significant. L value was significantly positively correlated with beta-carotene, positively correlated with pH value, and negatively correlated with lycopene and aab. The contribution rate of the first three principal components was 83.721%, which could reflect most of the variation information of the tested traits. The contribution rate of the first factor was 45.728%, the second and third principal factors were 18.443% and 16.793%, respectively. 【Conclusion】 In processing tomato breeding, the combination of high content of soluble solids and lycopene should be selected in order to obtain high yield and good quality varieties.
