Abstract: By analyzing and comprehensively evaluating the fruit quality of different varieties of peach (Prunus persica (L.) Batsch) in Xiaogan City, Hubei Province, this study provided a basis for the selection and promotion of local excellent peach varieties. During the ripening period of the fruit, the indicators such as single fruit weight, longitudinal diameter, transverse diameter, soluble solids content, and hardness of the peach fruit were measured. The entropy weight method was used to calculate the comprehensive scores of each indicator, and significant differences were analyzed. The results indicated that there were obvious differences in fruit quality among different peach varieties. Among them, Chunmi, Chunmei and Zhongtao No. 9 showed outstanding performance in terms of single fruit weight, significantly higher than other varieties(P<0.05); Dahongpao and Zhongyou Jinshuai had higher soluble solids content and better sweetness; the fruit hardness of Zhongyoupan No. 5 was the highest; in terms of longitudinal diameter, transverse diameter, and fruit shape index, each variety also exhibited different characteristics. The comprehensive evaluation results showed that the quality of three varieties, Zhongtao No. 9, Chunmi and Chunmei, was relatively good.
