摘要： 本研究在拉萨地区以16个燕麦（Avena sativa）引进品种作为研究对象，利用常规分析方法对干草产量、株高、茎粗、叶茎比、旗叶长、旗叶宽、粗蛋白（Crude Protein，CP）含量、粗脂肪（Ether Extract，EE）含量和相对饲草品质（Relative Feed Quality，RFQ）值进行测定分析，采用灰色关联度评价方法进行综合评价，以期筛选出适宜拉萨地区种植的燕麦种质。结果表明：爱沃的干草产草量和叶茎比最高，分别为10 371.57 kg·hm-2和0.5，甜燕麦的株高最高，达到138.13 cm，贝勒2茎粗、旗叶长、旗叶宽最高，分别为7.11 mm，36.49 cm，10.04 mm，白燕7号EE含量最高，为2.45%，魅力CP最高，为9.19%，牧王RFQ最高，为165.86。灰色关联度分析法综合分析结果表明，贝勒2、牧王、爱沃和甜燕麦4个品种在生产性能和营养品质上表现良好，适宜作为牧草在拉萨地区进行推广种植。

Abstract: In Order to study suitable forage germplasm for the Lhasa,16 oat varieties were assessed. Four nutritional traits and six agronomic traits were determined and analyzed by conventional analysis,and the comprehensive evaluation was carried out by grey relational analysis method. The results showed that the Everleaf had the highest hay yield(10 371.57 kg·hm2) and highest leaf stem ratio(0.5),Tianyanmai had the highest plant height(138.13 cm),Baler 2 was the best in stem diameter(7.11 mm),flag leaf length(36.49 cm) and flag leaf width(10.04 mm),Baiyan NO.7 had the highest ether extract (2.45%),Charisma had the highest crude protein (9.19%),Haymaker had the highest RFQ(165.86). The grey relational analysis results showed that Baler 2,Everleaf,Haymaker and Tianyanmai were better suitable for planting in this area.
