摘　　要：为了评价不同苜蓿种质资源在齐齐哈尔地区的表现,试验对引进的30份国内外苜蓿种质资源单株的物候期、抗寒性、茎叶性状以及单株产量进行测定、评价。结果表明:育成品种、地方品种和引进品种在物候期、抗寒性和茎、叶、单株产量性状方面存在差异。育成品种和地方品种较引进品种不仅返青早,而且单株产量性状较优。返青较早的苜蓿品种有肇东苜蓿、海拉尔黄花苜蓿和草原1号苜蓿。单株干草产量在450 g以上的有5个,分别为肇东苜蓿、龙牧801苜蓿、龙牧803苜蓿、公农1号苜蓿、甘农1号杂花苜蓿。30 alfalfa germplasm resources were assessed by analysis of the phenophase, cold resistance and yield performance. The results showed that difference was revealed among bred varieties, loc~ varieties and introduced varieties, involving in aspects of phenophase, cold re- sistance, leaf, stem and yield per alfalfa plant; the bred varieties and local varieties not only showed turning green earlier but also have more plant yield than that of the introduced varieties, including Zhaedong, Hailar huanghua and Caoynan No. 1. Furthermore, the alfalfa of yield per plant above 450 g are Langmu 801, Longmu 803, Gongnong No. 1 and Gannong No. 1.
