[ Objective ] To thoroughly understand and compare the characteristics and production values of the new wheat variety Jingdong 22. [ Method ] Based on performance in the National Yield Potential Trial, compared with the control variety, the characteristics and yield compo-nents of Jingdong 22 were analyzed. [ Result] The results indicated that Jingdong 22 had harmony yield components and top yield potential a-mong 15 varieties tested in 30 locations. The averaged yield of Jingdong 22 was 5.3 % higher than that of Jingdong 8 in the National Yield Po-tential Trial and production trial, with a significant difference. [ Conclusion ] Jingdong 22 showed high yield potential, excellent yield stability and adaptability. It was approved in 2007 for release and production.
