Abstract: Six cowpea varieties from Jianghan University and Hubei Province Engineering Research Center for Legume Plants were used as the experimental subjects, and the local variety（‘Zhaibuwan’） was selected as the control.The agronomic traits, nutritional quality and yield were compared according to randomized block test, and the comprehensive evaluation was carried out, in order to provide reference for the introduced cowpea varieties.The results showed that vitamin C content of ‘Cowpea No.7’（EJD-7）,‘Cowpea No.14’（EJD-14） and ‘Cowpea No.6’（EJD-6） was significantly higher than that of CK.The crude fiber content of EJD-7,‘Cowpea No.2’（EJD-2） and ‘Cowpea No.12’（EJD-12） was significantly higher than CK.The crude protein content of cowpea varieties EJD-14 and EJD-7 was significantly higher than that of CK.The yield of cowpea varieties ‘Cowpea No.6’（EJD-6）,‘Jiangda Cowpea No.1’（ZJD-1） and EJD-14 was significantly higher than that of CK.According to membership function analysis, the comprehensive performance of cowpea varieties tested from priority to poor was EJD-14,EJD-6,EJD-7,EJD-2,ZJD-1,CK,EJD-12,respectively.And the average membership function values were 0.951,0.721,0.478,0.447,0.399,0.388 and 0.277,respectively.Therefore, EJD-14 and EJD-6 had the best comprehensive performance in Bazhou area of Xinjiang, which have great potential for large-scale promotion in Bazhou area.
