Abstract：To provide a reference for the introduction and breeding of high quality varieties of facility long cowpea in the coastal areas of Guangxi,the grey relational analysis method was used to comprehensively analyze 17 indicators includ-ing the main agronomic traits,quality traits,and storage tolerance of 31 long cowpea varieties.The results showed that the coefficient of variation of agronomic traits among the varieties ranged from 6.59％to 34.05％,with the lowest for single pod number being 6.59％,and the highest for double pod ration reaching 34.05％.For quality traits,the variation coeffi-cients ranged from 14.25％to 30.94％,with soluble sugar content showing the lowest variation,and vitamin C content the highest.Chuanqi 108,Yuquan No.3,and Jiangshanmei had the smallest changes in density,seed to pod fresh mass ratio,and weight loss ration,respectively.Grey correlation analysis revealed that 19 varieties,including Lixin No.12 and Tianyuanlüfei,ranked higher than the control variety in terms of both equal weight correlation and weighted correlation.Combined commodity analysis,six varieties including Tianyuanlüfei,Degang,Nongfeng No.3,Youlemei,Jingke No.12,and Nongfeng No.12 had shown excellent comprehensive performance.In summary,six varieties including Tianyu-anlüfei can be promoted and applied as excellent facility long cowpea varieties in the coastal areas of Guangxi.
