摘　　要：为筛选适合在乌兰察布地区旱作条件下推广种植的优质饲用燕麦(Avena sativa L.)品种,对12个国内外燕麦品种的农艺性状、产量性状和营养品质进行测定分析。结果表明:不同燕麦品种在乌兰察布地区的产量性状差异较大,‘白燕1号’‘百事’‘摩登’和‘麦迪逊’4个品种的鲜草产量超过了20000 kg·hm^(-2),干草产量‘麦迪逊’最高达5892.23 kg·hm^(-2),干鲜比最高的是‘迪昂’和‘优牧1号’;粗蛋白含量最高的品种是‘迪昂’‘悍马’和‘优牧1号’,酸性洗涤纤维最低的是‘莫妮卡’,中性洗涤纤维最低的是‘悍马’,相对饲喂价值最高的为‘悍马’和‘莫妮卡’。叶占比对于燕麦品质的影响显著,与粗蛋白和相对饲喂价值呈显著正相关(P<0.05)。灰色关联度分析结果表明,16个指标中权重系数排在前5位分别是茎粗、株高、干草产量、穗占比和粗蛋白含量。综合生产性能和营养品质表现,兼顾高产优质,乌兰察布地区推荐‘悍马’‘迪昂’和‘优牧1号’。The agronomic characteristics,yield traits,and nutritional quality of 12 domestic and foreign oat varieties were analyzed to select high-quality forage oat varieties for widespread cultivation under dry farming conditions in the Wulanqab area.The results revealed significant variations in yield traits among different oat varieties in the Ulanqab area.‘Baiyan No.1’‘Pepis’‘Morden’and‘Madison’exhibited exceeding 20000 kg·hm-2 fresh grass yields.‘Madison’showed the highest hay yield,more than 5892.23 kg·hm-2.‘Diang’and‘Youmu No.1’had the highest dry-fresh ratio.Dion,Hummer,and‘Youmu No.1’displayed the highest crude protein content while‘Monica’had the lowest acid detergent fiber content and‘Hummer’had the lowest neutral detergent fiber content.‘Hummer’and‘Monica’showed the highest relative feeding value.Leaf proportion exerted significant influence on oat quality and demonstrated positive correlation with crude protein content and relative feeding value(P<0.05).Grey correlation degree analysis indicated that stem diameter,plant height,hay yield,spike ratio,and crude protein content were the top five influential factors out of sixteen indexes.Considering comprehensive production performance along with nutritional quality performance while prioritizing high yield combined with high quality attributes,‘Hummer’‘Dieng’and‘Youmu No.1’were recommended for cultivation in Ulanqab region.
