摘　　要：熟性、产量和纤维品质是超早熟短季棉育种研究内容的重点。实现河北省中南部地区棉麦连作需要选育生育期在110 d左右、产量高于或与同等条件下春播棉相当、纤维品质符合国家审定标准的稳定棉花品系。国家半干旱农业工程技术研究中心通过连续对500余份早熟棉种质材料进行系统选育和多亲本的复合杂交,2011年在选育并审定通过了夏早2号和夏早3号2个品种后,又优选出超早熟短季棉稳定品系20个,其中高产品系3个、高强力品系3个、中长绒棉苗头品系1个。The maturity, yield and fiber quality are important contents in super early mature cotton breeding. In order to realize cotton-wheat double cropping in central and southern of Hebei Province, cotton stable strain should be selected which the growth period was about 110 days, the yield was higher or equivalent to spring sowing cotton, fiber quality meet national certification standards. Through continuous system selection and composite cross with multiple parents of more than 500 copies of early maturing cotton germplasm materials by The Semi-arid Agriculture Science and Technology Research Center of China, 20 excellent super early mature cotton strain were bred after Xiazao No. 2 and Xiazao No. 3 which bred and approved through the national crops variety examination and approval committee in 2011, among them there were three high yield strains, three high tensile strains, one long and medium staole cotton strain.
