Abstract
This experiment explores the production performance of different forage oat varieties in the Ordos region.Eight indicators,including stem diameter,number of internodes,number of leaves,effective tillering number,plant height,fresh grass yield,hay yield,and seed yield,were tested and evaluated comprehensively using the grey correlation method.The results showed that Mengsiyan 1 had the highest stem thickness and plant height,at 3.28 mm and 113.61 cm respectively.Wuyou 1 had the highest number of internodes and leaves,at 6.1 and 5.47 respectively.Baiyan 14 had the most effective tillers,with 196.Mengyan 1 had the highest fresh grass yield,dry grass yield,and seed yield,at 27 666.67 kg/hm2,8 410.67 kg/hm2,and 3 266.67 kg/hm2 respectively.The variety with the highest grey correlation comprehensive evaluation was Mengyan 1,Tianyan 1,and Qinghai 444.The comprehensive performance traits of the three varieties are outstanding and suitable for promotion and application in the Ordos region.
