Abstract: Aiming at the production performance of alfalfa in Ili Valley, ten alfalfa varieties were selected as materials, the phenological period, plant height, grass yield, leaf-stem ratio and dry-fresh ratio were analyzed and evaluated. The results showed that the ten alfalfa varieties were able to complete their life history in the test area, the growth rhythm change was consistent, the high-yield period appeared in the second year; the plant height and grass yield decreased gradually with the increase of cutting times. In the second year, after three cutting times, the dry yields of‘Bingchi’,‘Cavaliers’,‘Warrior’,‘Sanditi’,‘Barricade’were all above 11500 kg/hm2, and they had the characteristics of high plant, high yield and high dry- fresh ratio, the comprehensive performance was better, and they were suitable for popularizing. The indexes of‘Ladino’, ‘5010’,‘FY310’and‘Rugged’were medium, which could be used as supplementary candidates for promotion;‘Aohan’showed worse performance in the test area, which was not suitable for promotion in Ili Valley.
