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。
In order to evaluate the performance of different alfalfa germplasm resources in Qiqihar region, the phenological period, cold resistance, stem and leaf traits and yield per plant of 30 alfalfa germplasm resources introduced at home and abroad were measured and evaluated. The results showed that there were differences in phenotypic, cold tolerance, yield characters of stems, leaves and single plants among bred varieties, local varieties and introduced varieties. Bred varieties and local varieties than the introduction of varieties not only returned to green early, and per plant yield better. Medicago sativa varieties older than Zhaodong alfalfa, Hailar alfalfa and Prairie No. 1 alfalfa. There were 5 single hay plants with a yield of 450 g or more, including Zhaodong alfalfa, Longmu 801 alfalfa, Longmu 803 alfalfa, Gongnong 1 alfalfa and Gannong 1 alfalfa.
