摘　　要：选用25个国内外育成的不同生态型饲草燕麦(Avena sativa)品种,采用随机区组试验设计,测定并分析各品种农艺性状、营养品质,同时采用主成分分析法和聚类分析法进行综合分析,鉴选出适宜山西雁门关地区种植的饲草燕麦品种,为推广应用提供一定的理论依据。结果表明:1)‘青海444’生育期为74 d,属早熟品种;‘牧王’生育期最长,为88 d。‘白燕7号’和‘陇燕2号’干草产量最高,显著高于‘福燕A126’‘甜燕1号’‘甜燕2号’和‘青牧4号’(P<0.05)。2)各品种间粗蛋白含量无显著差异(P>0.05),水溶性碳水化合物(WSC)含量以‘甜燕3号’含量最高,中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量最低的是‘白燕7号’。3)主成分分析结果显示,前6个主成分累计贡献率达到83.6972%;聚类分析将25个饲草燕麦品种分为5类。综合分析表明,适宜在雁门关地区推广的品种为‘白燕7号’‘陇燕2号’‘陇燕3号’。The agronomic traits and nutritional quality of 25 forage oat(Avena sativa)varieties from different ecotypes bred locally and abroad were determined and analyzed using a randomized block design,and forage oat varieties suitable for planting in the Yanmenguan area of Shanxi Province were screened by principal component and cluster analyses.The study provides a theoretical basis for variety popularization and application.The results showed that:1)The growth period of‘Qinghai 444’was 74 days,and it was an early maturing variety;‘Haymarker’had the longest growth period of 88 days.‘Baiyan No.7’and‘Longyan No.2’had the highest hay yields,which were significantly different from‘Fuyan A126’,‘Tianyan No.1’,‘Tianyan No.2’,and‘Qingmu No.4’(P<0.05).2).There were no significant differences in the crude protein content,while the water soluble carbohydrate content of‘Tianyan No.3’was the highest,and the neutral detergent fiber and acid detergent fiber contents of‘Baiyan No.7’were the lowest.3)The principal component analysis showed that the cumulative contribution rate of the first six principal components reached 83.6972%,while the cluster analysis divided the 25 forage oat varieties into five groups.According to this comprehensive study,the‘Baiyan No.7’,‘Longyan No.2’and‘Longyan No.3’varieties are suitable to be popularized in the Yanmenguan area.
