Kaimai 22 is a new wheat variety bred by workers at Kaifeng Institute of Agricultural and Forest Sciences through sexual hybridization,with Zhoumai 18 as female parent and Aikang 58 as male parent. This variety is characterized by short stalk,high and stable yield,broad adaptability,high disease resistance and middle mature period. In the Henan Provincial New Wheat Varieties Regional and Productive Trial during 2011-2013,the average yield was 7 237. 50 kg / hm2,which enhanced by 2. 25% compared with Zhoumai 18. In production trial during 2013-2014,the average yield was 8 545. 50 kg / hm2 in Henan Province,which enhanced by 6. 00% compared with Zhoumai 18. The variety was released by Crops Varieties Approval Committee of Henan in 2014. We analyzed and described the breeding process,yield performance,qualities,characteristics and cultivation techniques,aiming at expanding Kaimai 22 and meeting the requirements of market.
