Abstract: 【Objective】 The high yield and adaptability of varieties(lines)participating in the naked oats regional test in China from 2003 to 2014 were determined,and suitable planting sites were devided to provide a basis for the promotion of the varieties. 【Methods】 The standard deviation of means(SD)corrected GGE-Biplot(SD-GGE)method was used to evaluate the high yield and adaptability of 4 rounds of trials and 30 naked oat varieties in 21 pilots. 【Results】 The analysis of variance showed that the environment was the main factor affecting yield changes,accounted for 47.53%-83.95% of the total variation. On the GGE-Biplot,9418,Bayou No.10,Mengyan No.2 and Zhangyou No.7 were higher yields in most of the pilots tested. In all 4 rounds of trials,the high yield of all varieties in the Wuzhai County in Shanxi Province was basically the same as the order of the average yield of all the experimental sites. 【Conclusion】 9418,Bayou No.10,Mengyan No.2 and Zhangyou No.7 were high yield and strong adaptability varieties. Wuzhai County in Shanxi Province was a good respresentative of all the sites.
