Abstract：To screen out high-quality Cucurbita maxima varieties suitable for cultivation in areas along the Yangtze River of Jiangsu province,14 C.maxima varieties were tested under the vertical trellising cultivation.By measuring the traits of these varieties and applying methods such as significance difference analysis and principal component analysis,a compre-hensive evaluation and selection of different varieties were conducted.The results showed that Beibeilü 1 has an early flowering period,strong disease resistance,good taste,and higher total sugar and vitamin C content;Huiguniang/Ruifu has the highest total sugar content(12.89％);Zhuyan has the highest reducing sugar content(6.70％);and Baijingua/Libai has the highest yield per plant(1.69 kg).The comprehensive evaluation found that among small-fruited types,Beibeilü 1 and Sweet pudding ranked first and second,respectively,while among medium-fruited types,Baijingua/Li bai,Huiguni-ang/Ruifu,Zhuyan,and Jiaoyang ranked in the top four.Due to its poor taste and low market acceptance,Baijingua/Libai,and Huiguniang/Ruifu is less recommended.In contrast,Beibeilü 1,Sweet pudding,Jiaoyang,and Zhuyan are most suit-able as the main promoted varieties for the areas along the Yangtze River of Jiangsu province.
