Abstract: In alpine region,Avena sativa L.is a forage crop for animal and also a cereal food for human due to its high contents of protein,fat,and linoleic acid.This study evaluated the agronomic characters,forage yield characters,and seed qualities of 11 oat varieties in Bashang,Hebei Province.The results show that all the tested varieties had a good adaptability to local environment according to their agronomic characters.The principal component analysis was applied to the 10 involved characters and the contribution rate of five principal component factors reached to 92.091%.Bayou 5 was the most suitable variety in the alpine region of Bashang,Hebei Province with the highest principal component score and integrated score among all tested varieties.It had higher forage and seed yields,more tillers number per plant,and 1000-grain weight 28.4 g,and higher contents of crude protein and linoleic acid in seeds.

Key words: Avena sativa L., Adaptability, Seed quality, Evaluation

摘要: 在河北坝上地区,对11个燕麦(Avena sativa L.)品种的农艺性状、产量性状和籽实品质性状进行测定评价。结果表明:供试品种的农艺性状对当地的适应性均较好;对10个性状进行主成分分析,得出累积贡献率达到92.091%的5个主成分因子;对各品种的主成分得分和综合得分值分析表明,坝优5号燕麦综合得分最高,其产草量和种子产量高,单株分蘖数多,千粒重达28.4g,籽实的粗蛋白和亚油酸含量较高,为供试品种中最适合在坝上地区种植的燕麦品种。
