摘　　要：45A is a glutinous sorghum male sterile line with high starch and high combining ability bred by Rice and Sorghum Institute of Sichuan Academy of Agricultural Sciences in 1998, it is a coeno-species taking non-glutinous maintainer line TL169-239B which bred by Tieling Institute of Agricultural Sciences in 1991 as the female parent and glutinous maintainer line72B bred by the authors＇ institute as the male parent, then, based on the backcross breeding between glutinous single plant chosen from F2 segregation population and Tx623A. There are ten hybrid sorghum varieties which already have been examined and approved by national and above provincial（municipal） level units; the patent of this breeding method has been authorized （the patent number： ZL 2012 1 0129155.6）; 45A is protected by the Right of New Varieties of Plants, MOA, P.R. China （the variety right number： CNA20090576.1）. In this paper, the breeding process of 45A and the characteristics of 45A sterile line and its hybrid sorghum were summed up, what＇s more, the technical key points of high-yielding breed of 45A and the production of hybrid sorghum seeds were introduced, to provide data for further popularizing the sterile line.45A是四川省农业科学院水稻高粱研究所1991年以辽宁铁岭市农科院育成的粳质保持系TL169-239B为母本与本所育成的糯质保持系72B为父本杂交,从F2分离群体选择糯质单株与Tx623A回交转育,于1998年育成的高淀粉高配合力糯质高粱不育系,已育成审定10个杂交高粱品种通过国家和省市审定,其育种方法获国家发明专利授权(专利号:ZL 2012 1 0129155.6),45A获得农业部植物新品种权保护(品种权号:CNA20090576.1)。该文总结了45A的选育过程及45A不育系和其所配杂交高粱的特征特性,最后介绍了45A高产繁殖和杂交高粱制种技术要点,为该不育系进一步推广应用提供资料。
