Abstract: 【Objective】To screen naked oat varieties(lines) suitable for cultivation in Ulanqab City,Inner Mongolia and lay a theoretical foundation for the introduction of oat varieties,breeding,demonstration and promotion of new varieties in the area.【Methods】Using 12 newly bred naked oat varieties(lines) in China as experimental material,in single factor randomized block experiments,the growth period,main agronomic traits,yield and quality traits of the different oat varieties(lines) were analyzed.【Results】All of the 12 naked oat varieties(lines) tested could mature normally in the local area. The varieties(lines) with better main agronomic traits were:201229-1-2,Zhangyou No.8,Bayou No.18. Bayou No.18 had better performance in plant height(136.10 cm),main panicle length(22.03 cm),grain weight per spike(2.94 g),tiller number(3.58) and 1000-grain weight(30.14 g). 201229-1-2 performed better in tiller number(4.20),spikelet number(35.73) and grain weight per spike(2.06 g). Zhangyou No.8 had better performance in 1 000-grain weight(30.14 g). The varieties(lines)with better yield performance were Bayou No.18,201229-1-2 and Baiyan No.16,at 3 250.05,3 330.00 and 3 157.80 kg/hm2,respectively. The varieties(lines) with better quality traits were Zhangyou No.9(highest protein content at 16.57%),Jinyan No.18(highest β-glucan content at 5.00%),Weiduyou No.5(highest starch content at 61.98%),and 201229-1-2(highest crude fat content and grain bulk density at 5.51% and 709.00 g/L). Principal component analysis showed that the comprehensive scores of Bayou No.18,Baiyan No.16,Zhangyou No.8,and 201229-1-2 were higher,with relatively prominent yield traits and nutritional quality traits.【Conclusion】The naked oat varieties(lines) with better comprehensive traits were Bayou No. 18,Baiyan No. 16,Zhangyou No. 8,and 201229-1-2. They were suitable for promotion and cultivation in Ulanqab City,Inner Mongolia,with Bayou No. 18 being particularly prominent.
