Abstract: To screen out high quality alfalfa varieties suitable for the climate of Dongting Lake area, the yield and quality characteristics of 14 varieties of alfalfa were evaluated in Hanshou County, Changde City, Hunan Province. The results indicated that the first year of planting had five times mowing, the first batch hay yield was the highest, and the yield of hay decreased with the increase of the mowing number. There was a significant correlation between the average height of the whole year and the dormancy grade (P<0.01), the plant height of the high dormancy grade variety was significantly higher than that of the low dormancy grade variety. The quality of all varieties of hay reached the special grade or primary standard, and five varieties ‘WL525’,‘55v12’,‘Jili’,‘Nanmu 701’,‘L656’ranked top, suitable for growing in Dongting Lake area.
