Research on screening and evaluation of suitable oat varieties in the Liangshan region
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,3.326 7 million plants/hm2,31 307.33 kg/hm2,and 4 984.16 kg/hm2,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 4 807.43 kg/hm2.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％,and β-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.
