Abstract: In order to screen high-quality flavor tomato cultivars and clarify the quality indexes of highquality tomato, the indexes of commodity characters, flavor quality and nutritional quality of 22 different tomato cultivars were determined in the solar greenhouse, and the measured indexes were quantitatively analyzed by using the analytic hierarchy process (AHP), and the comprehensive evaluation system of tomato fruits was established. Based on the above, the high-quality tomato cultivars were determined. The results showed that the order of coefficient weight of tomato quality indexes was lycopene > soluble sugar > soluble solid matter > vitamin C > hardness > organic acid > soluble protein > ratio of sugar and acid > single fruit weight > fruit shape index. The sum of lycopene and soluble sugar weight coefficient was 0.646 4, which was the most important index to determine the nutritional quality of tomato fruit. According to the fruit shape index,
single fruit quality and hardness index, the cultivars with better commercial characters were selected as 'Ruixing
No.5' 'Yibaifen-5' and 'Zhongza 302'. According to the indexes of soluble solid matter, organic acid, sugar
acid ratio and soluble sugar content, the cultivars with better flavor quality were selected as 'HuiFu' 'Galaguo'
and 'Tuerqi'. According to the content of soluble protein, vitamin C and lycopene, the cultivars with better
nutritional quality were selected as 'HuiFu' 'Jingfan 309' and 'Tuerqi'. Based on the comprehensive evaluation of
yield and quality, the five cultivars of 'Jingfan 401' 'Ruixing Dabao' 'Jinpeng No.8' 'Jingfan 309' and 'Provence'
were finally determined as high-quality and high-yield tomato cultivars. |
