摘　　要：通过栽培大豆品种间杂交育成的M型质核互作雄性不育系W931A ,雌雄育性稳定 ,农艺性状优良 ,可在黄淮地区直接使用。W931A的雄性不育是属配子体不育类型 ,用它作亲本育成 3个增产幅度达 2 9%～ 46The male sterile line W931A with stable male-female feritility and fine agronomic characters was bred through mutual crossing among soybean cultivated varieties. The sterile character of W931A was identified as gametocytic sterility. Three high yield combinations with W931A as maternal which increased yield by 29-46% had been selected.
