In order to select suitable alfalfa cultivars of Medicago sativa for Heilongjiang province,8 alfalfa cultivars from home and abroad were taken to compare the phenological period,returning green rate,plant height and yield traits.The result showed that there were significant differences of growth stages among different alfalfa cultivars;The returning green rate of alfalfa from domestic were better than foreign alfalfa cultivars,whose reterning green rate decreased evidently in the third and fourth year;Mowing height of Nongjing No.1 was higher than that of other cultivars,the second or third mowing height of Zhaodong were higher than those of other cultivars;The yield of Zhaodong was the highest,followed by Nongjing No.1 and Caoyuang No.1,Aohan was the lowest,the yield of foreign cultivars were decreased evidently in the third year.It comprehensive evaluated that Nongjing No.1,Zhaodong,Caoyuan No.1 and Longmu 801 owned good comprehensive properties,high and stable yield,they were suitable for planting in Heilongjiang province.
