凉山地区适宜燕麦品种筛选评价研究

Research on screening and evaluation of suitable oat varieties in the Liangshan region

试验旨在筛选出适宜凉山地区种植的粮饲兼用燕麦品种。试验选取5个燕麦新品种,测定农艺性状、产量、营养成分等。结果表明,白燕10号株高、有效分蘖数、牧草产量、种子产量均最高,分别为151.14 cm、332.67万株/hm^(2)、31307.33 kg/hm^(2)和4984.16 kg/hm^(2),白燕10号的千粒重位居第二,为23.60 g。坝莜14号千粒重最高,为24.60 g,种子产量位居第二,为4807.43 kg/hm^(2)。不同燕麦品种种子的粗蛋白含量为15.65%~18.93%,粗脂肪含量为5.00%~8.21%,粗淀粉含量为55.84%~60.39%,β-葡聚糖含量为4.09%~5.19%。白燕10号和坝莜14号的等权关联度、加权关联度排名前两位。研究表明,白燕10号和坝莜14号综合性状均高于其他品种,适宜在凉山地区推广种植。

The experiment aimed to screen for oat varieties suitable for both grain and forage use in the Liangshan region.The trial selected five new oat varieties and measured agronomic traits,yield,nutritional components,etc.The results showed that Baiyan No.10 had the highest plant height,effective tiller number,forage yield,and seed yield,which were 151.14 cm,3.3267 million plants/hm^(2),31307.33 kg/hm^(2),and 4984.16 kg/hm^(2),respectively.The thousand-kernel weight of Baiyan No.10 was the second highest,at 23.60 g.The thousand-kernel weight of BaYou No.14 was the highest,at 24.60 g,and its seed yield was the second highest,at 4807.43 kg/hm^(2).The crude protein content of the seeds from different oat varieties ranged from 15.65%to 18.93%,crude fat content from 5.00%to 8.21%,crude starch content from 55.84%to 60.39%,andβ-glucan content from 4.09%to 5.19%.Baiyan No.10 and BaYao No.14 ranked in the top two for both equal-weight and weighted association degrees.The study indicates that Baiyan No.10 and BaYou No.14 have higher comprehensive traits than other varieties and are suitable for promotion and cultivation in the Liangshan region.
