Abstract：To optimize the variety structure of facility-cultivated eggplants in northern Xinjiang and select high-yield,high-quality,and disease-resistant eggplant varieties suitable for local cultivation,this study compared five eggplant vari-eties in terms of phenological stages,growth periods,botanical traits,yield,and fruit nutritional components including solu-ble sugar,soluble protein,vitamin C,vitamin P,relative total phenol content,relative flavonoid content,and relative antho-cyanin content.A comprehensive evaluation was conducted using the membership function method.The results showed that Lüfeng No.1 performed the best in terms of comprehensive yield and quality,with a yield of 9 690.56 kg·667 m-2,representing a 7.98％increase compared to the control.Its in soluble sugar content(33.44 mg·g-1)and pericarp vitamin P content(1.23 mg·g-1)were significantly higher than those of other varieties,and its membership function value was 0.696 8,ranking first.Purple round eggplant had the highest single-fruit mass(377.12 g),and its pericarp relative total phenols content and anthocyanins content were the highest among the five varieties.Green round eggplant exhibited outstanding soluble protein content(3.94 mg·g-1)and pericarp vitamin C content(13.61 mg·100 g-1).Correlation analysis revealed a highly significant positive relationship between plant height and fruit length as well as yield,while soluble sugar exhibit-ed significant positive relationship with soluble protein content and peel vitamin C content.In conclusion,Lüfeng No.1 combines high yield and nutritional advantages,making it the primary recommended variety for facility cultivation in northern Xinjiang.Purple round eggplant serves as a functional variety to meet market demands,and Green round egg-plant holds potential for development due to its high protein content.
