摘　　要：用大豆中油８９Ｂ（代号Ｗ２０２）品种作母本，分别与Ｗ２０３、Ｗ２０６、Ｗ２０７３个品种杂交，在Ｆ１代发现不育株；通过正反交测定，属质核互作型；通过连续４～５代核置换回交，获得雌、雄育性较稳定的３个不育系Ｗ９３１Ａ、Ｗ９３６Ａ、Ｗ９３３Ａ；这些不育系是栽培大豆与栽培大豆杂交后获得的，故定名为Ｍ型质核互作雄性不育系。Sterile plants were found in F 1 from crosses with soybean variety Zhongyou 89B(W 202 ) as maternal crossed respectively with varieties W 206 , W 203 and W 207 as paternal,which was defined as nucleo cytoplasmic interaction through the examination of reciprocal crosses.Three sterile lines,W 931A ,W 936A ,W 933A ,with stable male and female fertility were obtained by 4～5 generation's backcrosses of nucleus substitution.The sterile lines were named as M male sterile line of nucleo cytoplasmic interaction because they were derived from the filial generation between soybean cultivars.
