Abstract: Persistence and forage yield are two important indexes in the introduction of new varieties. To select suitable varieties,35 Medicago sativa varieties which were planted in Zhangye Experimental Station of Lanzhou University in 2001 were investigated in 2011. The characteristics studied included persistence,hay yield,growth rate,and plant height. Gaps and branches were also measured. 1) The varieties with highest persistence were Prime,Weinan,Gongnong No.1,and Gannong No.2; 2) The varieties with best yields were Xinjiang daye,Gongnong No.1,Bear No.1,Rambler,YL-3 and Gongnong No.2; 3) The varieties with both high yield and persistence were Gongnong No.1,Xinjiang daye,Rambler,Gongnong No.2,Prime and Weinan. These varieties have good adaptability in the Hexi Corridor of Gansu province and are suitable for cultivation in this region.
