Abstract：In order to screen suitable varieties of alfalfa（Medicago sativa L.）for planting in Minqin area，this study used15 excellent domestic or foreign alfalfa varieties as experimental materials，and measured 17 trait indicators including overwintering performance，production performance，and nutritional quality.The adaptability was comprehensively evaluated through membership function method and cluster analysis method.The results indicated that‘WL343’had the highest overwintering rate of 94% ，‘Longmu 806⋅ had the highest number of crown buds，and‘Gannong 5’had the longest crown bud length． The soluble protein content of ‘Longmu 8Ol’was significantly higher than other varieties，‘WL343’had the highest total yield，and LW6010′ had significantly higher relative feding value than other varieties. Correlation analysis showed that plantheight， numberofbranches，leaf stem ratio，and hay yield were allsignificantly positively corelated.The soluble sugar content，soluble protein content，and number of crown buds were significantly positively correlated with overwintering rate.The membership function and clustering analysis results were consistent，and alfalfa varieties with the best comprehensive index were‘WL343’‘WL298’‘LW6OlO’and‘Juneng 551’， which could be recommended to planting in similar areas of Minqin and Hexi Corridor.
