摘　　要：抗逆丰产宜机采是农业提质增效背景下对棉花品种提出的新要求。衡棉HD008是河北省农林科学院旱作农业研究所以中早熟抗病陆地棉品种资源材料‘衡棉4号’为母本,以优质遗传资源材料RILNnXu-0022HF为父本杂交,后代多年南繁北育,经旱棚盐池鉴定筛选,在枯黄萎病混生重病地、不防治棉铃虫的高压胁迫下,多年连续定向选择育成的转Bt基因抗虫机采棉新品种。其突出表现为抗旱耐盐、优质高产、宜机采,适宜在河北省及黄河流域同类生态春播棉区机收种植,2019年8月通过河北省农作物品种审定委员会审定,审定编号为冀审棉20199003。Under the background of improving agricultural quality and efficiency,the new requirements for cotton varieties were put forward.Dryland Farming Institute,Hebei Academy of Agricultural and Forestry Sciences took’Hengmian 4’(resource material of middle-early maturity and disease-resistant upland cotton)as female parent and RILNnXu0022 HF(Resource material of high quality upland cotton)as male parent to carry out hybrid combinations.After years of continuous directional selection,Hengmian HD008 was selected under disease stress,pest stress,salt stress and drought stress.Hengmian HD008 has the outstanding performance of drought and salt tolerance,high quality and yield,suitable for machine picking,which was approved by Hebei Province in August 2019(Approved number:Jishenmian 20199003)and was suitable for planting in Hebei Province and similar ecological and spring sowing cotton areas in the Yellow River Basin.
