摘　　要：用紫花苜蓿Ｓａｒａｎａｃ、Ｔｈｏｒ、Ｅｕｒｏｐｅ、Ｖｅｒｔａｓ及杂种苜蓿Ｉｒｏｑｕｏｉｓ、Ａｌｇｏｎｑｕｉｎ与国产关中苜蓿、新疆大叶苜蓿及公农２号苜蓿品种进行了生产性能比较试验。结果表明，在黄土高原低平地带，正常年份牧草产量各品种间没有显著差异（Ｐ＞０．０５），但在多雨年份，７、８月形成湿热气候，造成所试品种减产，而公农２号苜蓿对湿热气候的耐力远胜过其他品种。国产３个品种春季返青都较引入品种早，生长速度以引入的Ｅｕｒｏｐｅ最快。国产的３个品种，在长日照下的头茬草生长速度较Ｅｕｒｏｐｅ之外的其余品种为快，但在短日照下的末茬草关中苜蓿和公农２号苜蓿较其他品种生长缓慢。A comparison of production performance between introduced varieties Medicago sativa cv.Saranac, Thor, Europe and Vertas, M.media cv. Iroquois and Algonquin and home varieties M.sativa cv. Guanzhong, Xinjiang Daye and Gongnong No.2 were conducted. The results showed that in low-flat area of Loess plateau their yield in normal years had no significant difference (P<0.05), but in rainy years it caused the yield decrease because of the wet and hot wether in July and August, and among them, Gongnong No.2 owned the biggest resistant ability to that wether. The three home varieties, their reviving in spring was earlier than the others, but the growth speed of Europe was the fastest. Under the condition of longday, the three home varieties’ growth speed in the first cutting was faster than other varieties except Europe, but Guanzhong and Gongnong No.2 slower than the others in short day in the last cutting.
