This paper systematically reviewed the breeding process, characteristics and supporting cultivation techniques of wheat variety Wankenmai 66. As a semi-winter wheat variety, it was bred through sexual hybridization combined with the pedigree selection method., using the F1 hybrid of Caizhi9888 and Wanmai 50 as the female parent and Jimai 22 as the male parent, and was approved by the Anhui Provincial Crop Variety Approval Committee in 2024 (Approval No. Wanshenmai 2024T018). Its total growth period is 223.7 days, with semi‑prostrate seedlings, and the yield components (spikes per mu, grains per spike, and 1000‑kernel weight) are well balanced. Resistance and quality evaluations from 2020 to 2022 showed moderate resistance to moderate susceptibility to Fusarium head blight, moderate susceptibility to moderate resistance to powdery mildew, and susceptibility to sheath blight. It is classified as a medium-gluten wheat in terms of quality type. In the 2020-2022 regional trials and production tests, its average yield ranged from 568.2 to 673.1 kg/667 m2, 5.73%-7.38% higher than that of the control Jimai 22. The supporting cultivation techniques included seed coating and straw returning before sowing, suitable sowing date from October 15 to 25, seeding rate of 12.5-15 kg/667 m2 and sowing depth of 3-5 cm, deep application of base fertilizer, emphasis on phosphate fertilizer, rational application of potassium fertilizer and the nitrogen application principle of “light at early stage, none at middle stage and heavy at late stage”, pre-emergence soil sealing and chemical weed control, prevention and control of sheath blight, crown rot, red spider, aphids and other diseases and pests at the 3-leaf-1-heart stage, early jointing stage and heading stage, optimized field management to prevent waterlogging and dry-hot wind, and harvesting when the grain moisture content drops to 16%. This study provides a reference for high yield and high quality cultivation of Wankenmai 66.
