为筛选适宜贵州种植的优质牧草品种，对国外引进的12个品种在贵州黔南地区进行了田间比较试验，对比分析了不同品种的物候期、株高及鲜、干草产量。结果表明：参试品种在试验区内均能正常生长、开花，但不能结籽，未完成整个生育周期；WL903、WL525HQ和 Magna995的株高较高，均在60 cm以上；WL903、Magna804和 WL525HQ年鲜草产量和干草产量最高，分别为50800 kg/hm2、13762 kg/hm2、47567 kg/hm2及13163 kg/hm2、53599 kg/hm2、13112 kg/hm2；同一品种鲜、干草产量均以第1茬和第2茬的最高，占全年总产量60％以上，显著高于第3茬和第4茬（P＜0．05），第4茬最低，仅占18％。

In order to screen high-quality alfalfa varieties suitable for planting in Guizhou,a field comparative test of 1 2 introduced alfalfa varieties was conducted in Qiannan Region to comparative and analyze the phenological phase,plant height,fresh and dry weight.Results:All tested varieties could grow and flower,but no seed,and couldn't finish the whole growth period.The plant heights of WL903, WL525HQ and Magna995 were more than 60 cm,significantly higher than others.The annual fresh and dry yield of WL903,Magna804 and WL525HQ were 50 800 kg/hm2,13 762 kg/hm2,47 567 kg/hm2 and 1 3 1 6 3 kg/hm2 ,5 3 5 9 9 kg/hm2 and 1 3 1 1 2 kg/hm2 .The yield of the first cutting and the second cutting was higher than the third and the fourth cutting,accounting for more than 60% of the total annual production.The fourth cutting yield were the least, only accounted for 18% of the total annual production.
