Abstract:

【Objective】Clarify the representative indexes for evaluating fruit quality and screen for excellent varieties of taste type tomatoes,to provide references for constructing quality evaluation systems of taste type tomatoes.【Methods】Using 17 taste type tomato varieties as experiment materials,10 quantitative trait indexes related to quality were tested. Factor analysis,stepwise regression analysis and correlation analysis were used to screen for the representative indexes for evaluating fruit quality. The quality of taste type tomatoes were then comprehensively evaluated.【Results】The variation of aromatic substance content was the largest among the 10 quantitative trait indexes related to quality,with a variation coefficient of 66.49%. With a variation coefficient of 9.56%,the variation of fruit vertical diameter was the smallest. The comprehensive quality analysis of the 10 indexes obtained 3 common factors,with a cumulative variance contribution rate of 80.267%. The explanatory indexes were fruit soluble solids content,reducing sugar content,single fruit weight,aromatic substance content,sugar-acid ratio and titratable acid content. According to the correlation between indexes,and the principle of easy to use and avoiding information overlap,four indexes of fruit soluble solids content,single fruit weight,aromatic substance content and sugar-acid ratio were selected as the representative indexes to evaluate the quality traits of taste type tomatoes. Using common factor scores and variance contribution rates,the comprehensive quality ranking of the varieties were calculated,and 7 high-quality taste type tomato varieties were selected.【Conclusion】Fruit soluble solids content,single fruit weight,aromatic substance content and sugar-acid ratio could be used as representative indexes to evaluate taste type tomatoes. The quality traits of Hangfengaotang,700,1933,Meidai,2001,Tianlian and Jingfan No.1 were better.
