Abstract: In this study,agronomic characters related to the adaptability of 30 different oat varieties in Tianzhu,Gansu Province including phenological phases,hay yield and ten major characters were investigated. The results showed that only 7 varieties completed the growth period in Tianzhu. Most of the varieties only reached milking stage. the highest hay yield was Yan wang(192.87 kg·100m-2),The results of path analysis showed that the panicle number,leaf width and plant height area are the biggest factors affecting hay yield in Tianzhu;Principal component analysis of nine characters related to adaptability indicated that the contribution rate of four principal component factors reached 81.33%. Accession Dinyan No.2 was the most suitable variety in the region of Tianzhu,Gansu Province with the highest integrated score compared to other tested varieties.

摘要: 为了客观评价30份燕麦(Avena sative)品种(系)在甘肃天祝地区的适应性,本试验测定并分析了燕麦物候期、干草产量以及10个主要农艺性状。结果表明:30个燕麦品种只有7个可以在天祝完成整个生育期,大多数品种只能达到乳熟;干草产量最高的是燕王(192.87 kg·100m-2);10个主要农艺性状和干草产量的通径分析结果说明天祝地区轮层数、叶宽、株高性状是影响干草产量的最大因素;对10个农艺性状进行主成分分析,得到累计贡献率81.33%的4个主成分因子;在主成分析的基础上进行综合评价,定燕2号综合得分最高,是供试品种(系)中最适宜在天祝地区种植的品种。
