摘　　要：以国内外15份燕麦种质为材料,对其物候期、生育期、主要农艺性状进行了测定,并开展了主要农艺性状的方差分析、相关分析、主成分分析和聚类分析,结果表明:种质W3、W6、W11生育期90~100 d,W1、W2、W4、W5、W9生育期100~110 d,W8、W10、W12、W13、W14、W15生育期大于110 d,分别为早熟、中熟和晚熟类型,均能在本地正常生长达到种子成熟,只有W7在本地区不能成熟;15份供试燕麦种质材料可聚成5类,聚类结果与种质的地理来源有一定的相关性;单株种子重与单株穗数、单株种子数呈极显著正相关;千粒重与种子长呈极显著正相关(P<0.01);种质W14、W15、W2综合农艺性状突出,可在本地区的燕麦育种研究中优先利用。W13单株干草产量最高,具有较大的饲草生产潜力。In this study, 15 oat germplasm resources of China and abroad were used, and their phenological period, growth period and 15 main agronomic characters had been tested. The characteristics of 15 oats were defined by variance analysis, correlation analysis, principal component analysis and cluster analysis. The results show as follows：Growing period of germplasm W3, W6, W11 are 90-100d, W1, W2, W4, W5, W9 are 100-110d, W8, Wl0, W12, W13, W14, W15 are more than 110d,belonging to precocious, medium and late ripening type, respectively. All of them can grow at local condition and reach seed maturation.Based on the main agronomic characters, the 15 oat germplasm materials can be grouped into 5 types, and the clustering results have some correlation to the provenance of germplasm.The per plant seed weight has significant positive correlation with per plant panicle number and per plant seeds number, the 1000-grain weight was positively correlated with seed length （P〈0.01）.Germplasm W14, W15 and W2 have better comprehensive agronomic characters, which can be used in the priority oat breeding of this region, W13 has the highest per plant yield, it has great potential of forage production.
