Abstract：Though the Loess Plateau dryland region in northern Shanxi is a keyoat-producing area in China，its forage productivityremains lowdue to limited rainfallandalack of suitableoat varieties.To identify high-quality， high-yield forage oat（Avena sativa） cultivars，we evaluated 38 widely promoted domestic and imported varieties，assessing their growth periods，agronomic traits，yields，and nutritional quality.The results showed that there was significant variation in maturity time （86-127 days），with late-maturing types predominating （21/ 38）.‘Molasses’ and‘Tianyan No. achieved the highest fresh （27 100 and 23500kg⋅hm-2） and dry forage yields （11 700 and 11500kg⋅hm-2 ）. Five cultivars-including‘Magnum’-had the highest soluble sugar content （16.4%-18.1%） ，while‘Shooter’‘Longyan No.2’and‘Longyan No. 1⋅ had the greatest crude protein content （8.7%-8.8%） . Seventeen varieties exhibited premium forage quality，with Relative Forage Value values of 113.7-126.1.Based on the“Quality Clasification of Oat Hay” standard，13 cultivars were clasified as Type A hay and 9 as Type B（all Grade II）. Overall，‘Molasses’‘Magnum’‘Tianyan No.3’‘Jiayan No.2，'and‘Monida’demonstrated superior performance and are recommended for priority adoption in eastern dryland areas of northern Shanxi's Loess Plateau.
