本文在研究“7623”恢复系恢复基因遗传规律的基础上,发现[野栽]农垦四号不育系内具有两对显性抑制基因,专性抑制“7623”恢复系内两对恢复基因的育性恢复作用,使其Fl代表现不育,回交、测交后代均出现异乎寻常的分离现象。并发现[野栽]南早、中杆早不育系,[野败]二九南、肯苏罗斯不育系,[冈]朝阳一号不育系,[辽]7624不育系,分别具有其中一对专性抑制基因,使其F_2代和测交后代出现51:13或5:3的分离比例。估计这种抑制基因与细胞质无关,但正常细胞质掩盖了它对恢复基因的抑制作用。在各种农作物细胞质雄性不育“三系”遗
Based on the study of the genetics of restoring genes in “7623” restorer, we found that there are two pairs of dominant inhibitory genes in “Nongken” Nongken No.4 male sterility line and the two pairs of restorer genes in “7623” restorer line Fertility restoration, so that the F1 on behalf of the current sterile, backcross, cross dating offspring have shown an unusual phenomenon. And found that [wild plant] South early, early barley in the bar, [wild defeat] two nine South, Ken Suluosi sterile line, [Gang] Chaoyang a sterile line, [Liao] 7624 sterile lines, respectively With one pair of obligate suppressor genes, the F 2 generation and the tested progeny appeared 51:13 or 5: 3 separation ratio. It is estimated that this suppressor gene has nothing to do with the cytoplasm, but the normal cytoplasm masks its inhibitory effect on the recovery gene. In a variety of crop cytoplasmic male sterility “three series” legacy
