AbstractThe breeding process and characteristics of wheat variety Qinglin 139 were summarized，and its high yield cultivation techniques in theregions along the Huai River and in Huaibei region were analyzed.This variety was developed through systematic breeding，with Jike32asthe female parentand Zhoumai 26asthe maleparent.In the 2019-2021 regional trials of the semi-winter wheat group in Anhui Province，the total growth period was recorded as 224.0-225.2 d，and its agronomic traits were excellent. The yield ranged from 8 004.0 to 8 292.0kg/hm2 ， representing an increase of 0.66 % -5.97% compared to Jimai 22.It exhibited moderate resistance to fusarium head blight， good stem elasticity，and strong lodging resistance.The average grain bulk density was 826g/L ， with a protein content （dry basis） of 13.49 % ，a wet gluten content of 30.0% ，and it was classified as medium-gluten wheat.High yield cultivation techniques included fine land preparation， deep plowing to 25-30 cm followed by leveling and compaction，and straw crushing to lessthan5cm.Base fertlization wasprimarily based onorganic fertilizer，supplemented with nitrogen，phosphorus， potassium，and zinc fertilizers.Additional nitrogen fertilizer wasappliedduring the jointing stage based onseedling conditions.The suitable sowing periodinthe regions along the Huai Riverand in Huaibei region was from October 15 to 25，with an appropriate seeding rate of 157.5-187.5kg/hm2 .Key disease prevention measures targeted sharp eyespot disease，using agents such as tebuconazole for seed dressing or spraying，combined with the application of potassium dihydrogen phosphate to enhance resistance.For mechanical harvesting，the stubble height was kept below 15 cm，and timely sun-drying after harvest was recommended to reduce grain moisture content to below 13% . This study provides a reference for the further promotion and cultivation of this variety.
