Abstract: Mengyan No.3 is a new type of shelled oats,which is cultivated by traditional hybridization methods.From 2009 to 2011,tests at 8 sites were conducted in Inner Mongolia,Hebei,Xinjiang,Qinghai and Jilin.The average yield was 4 190.7 kg/hm²,which was 16.1% higher than the control Qingyin 1. In 2013,the production demonstrations were conducted in 4 sites （Zhangbei county,Hebei;Qitai county,Xinjiang;Youyu county,Shanxi;Wuchuan county,Inner Mongolia）.The average yield was 3 736.5 kg/hm² in the four sites,which was 29.20% higher than Qingyan 1.Therefore,it suggests that Mengyan 3 is suitable for planting in Wuchuan county of Inner Mongolia Autonomous Region,Hezuo city of Gansu Province,Xining city of Qinghai Province,and similar ecological areas.In 2015,Mengyan 3 （2015019）was appraised and certified by the Small Grain and Bean Identification Committee.
