Abstract:

In order to deeply tap the utilization potential of tomato with different fruit colors in quality traits, 83 tomato germplasm with different fruit colors were used as materials to analyze the variation characteristics, correlation and cluster analysis of 17 main tomato quality traits. The results showed that the coefficient of variation of fruit weight of red tomato was the largest (101.05%), the coefficient of variation of vitamin C (VC) content of pink tomato was the largest (82.27%), the coefficient of variation of fruit weight of orange tomato was the largest (106.11%), the coefficient of variation of fruit weight of brown tomato was the largest (56.91%), and the coefficient of variation of lycopene of purple tomato was the largest (54.65%). Fruit color was positively correlated with lycopene content, and lycopene content was positively correlated with soluble solids content. The tested materials were divided into eight categories at the European distance of 9.5, of which six red tomatoes and one orange tomato were more durable and were clustered in class Ⅱ; three orange tomatoes were grouped into class Ⅴ, which tasted good; one red tomato and one puroke tomato had excellent nutritional quality and were clustered in class Ⅷ.
