Abstract: 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/hm2, 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.

Key words: maize(Zea mays L.), Yundan 22, breeding process, comprehensive characteristics, high-yield cultivation techniques
