Abstract：The ecological environment in the Qinghai Tibet Plateau region is complex and varied,and the vegetation is fragile,making restoration difficult.However,the development base of animal husbandry in the region is relatively large,and natural vegetation cannot meet the feeding needs of cattle and sheep.As an advantageous characteristic crop in the region,highland barley can meet the supply of cattle and sheep forage during the snow-capped season through straw flexible fermentation.Moreover,the variety of highland barley that can be used for both food and forage is increasingly favored by farmers and herdsmen,and the demand is constantly increasing.Ganqing No.12,a new variety of highland barley,is a dual-purpose variety for both grain and forage.It has a growth period of 111～116 days,a plant height of 99.7 cm,a full heading habit,an upright spike neck,a spike length of 6.0 cm,41.0 grains per spike,a spike-grain weight of 1.88 g,a thousand-grain weight of about 42.2 g,yellow and oval shaped grains,and is cold and drought resistant.The grain protein content is 10.85％,starch content is 55.41％,lysine content is 0.41％,and β-glucan content is 6.03％.The crude protein content of straw is 8.84％,soluble sugar is 6.80％,lignin is 9.47％,neutral detergent fiber is 70.6％,and acidic detergent fiber is 39.7％.The breeding of this variety can further lay the foundation for the supply and demand of grain and forage in the agricultural pastoral transitional zone of Gannan and surrounding areas.
