摘　　要：为深入挖掘不同果色番茄在品质性状方面的利用潜力,以83份不同果色番茄种质为材料,对17个主要番茄品质性状进行变异特征分析、相关分析和聚类分析。结果表明:红果番茄材料性状中变异系数最大的为单果重,达101.05%;粉果番茄材料性状中维生素C(V_(C))含量变异系数最大,达82.27%;橘黄果番茄材料性状中单果重变异系数最大(106.11%);棕果番茄材料性状中单果重变异系数最大(56.91%),紫果番茄材料的性状中番茄红素变异系数最大(54.65%)。果实颜色与番茄红素含量呈显著正相关,番茄红素含量与可溶性固形物含量呈显著正相关。供试材料在欧式距离9.5处被分为8大类,其中6份红果和1份橘黄果材料聚为Ⅱ类,具有耐贮运特性;3份橘黄色小果聚为Ⅴ类,口感好;1份红果和1份紫果材料聚为Ⅷ类,营养品质优异。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(V_(C))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 classⅡ;three orange tomatoes were grouped into classⅤ,which tasted good;one red tomato and one puroke tomato had excellent nutritional quality and were clustered in classⅧ.
