摘　　要：在甘肃兰州地区对国内外20个紫花苜蓿种质材料的生长高度、生长速度、再生速度、分枝数和草产量等多个生产性能构成因子进行了综合比较分析,评价出了供试苜蓿材料在该地区生产性能的高低。结果表明:国外材料游客、雷西斯、阿根廷、阿尔冈金、牧歌、大西洋和国内材料萨尔图、富平、新疆大叶综合表现良好,适合在该地区大面积推广种植。20 alfalfa（Medicago sativa L. ） varieties from home and abroad were tested during 2005-2006 in Lanzhou of Gansu province. The alfalfa varieties were evaluated on plant height, growth speed, regeneration speed, branch number and fresh yield, which were better performance on the production performance in Lanzhou. The results showed that the foreign alfalfa varieties of Eureka, Resis, Argentina, Algonquin, Amerigraz, Atlantic and the domestic varieties of Saertu, Fuping ,Xinjiangdaye were superior to other varieties ,which were generally suitable to Gansu province and could be suggested to be popularized in the regrion.
