摘　　要：玉米(Zea mays L.)新品种郧单22是十堰市农业科学院2020年育成的,组合为WD04×N75。两年区域试验平均产量为9670.72 kg/hm^(2),比对照宜单629增产4.51%,生育期110.7 d,株型半紧凑,抗逆、抗病性强,综合农艺性状好,适宜在湖北省丘陵平原地区作春玉米种植。总结概括了郧单22的选育过程、高产栽培技术、高产制种技术,助力该品种的示范推广。Yundan 22,a new maize variety(Zea mays L.),was bred by Shiyan Academy of Agricultural Sciences in 2020,and the combination was WD04×N75. The average yield of the two-year regional test was 9 670.72 kg/hm^(2),which was 4.51% higher than that of the control Yidan 629. The growth period was 110.7 d. The plant type was semi-compact,with stress resistance,strong disease resistance,and good comprehensive agronomic traits were good. It was suitable for spring maize planting in hilly plain areas of Hubei Province. The breeding process,high-yield cultivation techniques,and high-yield seed production techniques of Yundan 22 were summarized to help the demonstration and promotion of this variety.
