Abstract： The new naked -oat variety " Wuyou No.1" was bred by Maize Research Institute of Shanxi Agricultural University to adapt to the ecological conditions of northern Shanxi.It was bred through interspecific hybridization between Naked Oat of " Yong 73-1" and Naked Oat of " Huabei No.2"by pedigree selection.Field evaluations demonstrated that‘Wuyou 1’exhibits early maturity，high grain quality，high-density tolerance， drought resistance，lodging resistance and resistance to head smut.It has an average 1OOO-grain weight of 24.1 g and a β - glucan content of 6 . 5 7 % .Over two years of joint regional trials in Shanxi Province，the variety achieved an average grain yield of ，representing a 1 0 . 1 1 % increase compared to the control variety. In November 2O22，‘Wuyou1'was received oficial approval by the Crop Variety Approval Commitee of Shanxi Province.This variety efectively meets local demands for optimizing agricultural layout，adjusting crop rotation， and ensuring emergency preparedness.
