摘　　要：以粳稻显性半矮秆突变体Y98149为基因供体亲本与保持系8204B杂交、回交,利用分子标记辅助选择,在BC_1F_5中筛选出携带显性半矮秆sdt基因的粳稻新品系177,与BT型‘寒丰A'连续回交育成育性稳定、开花习性好、配合力强的显性半矮秆杂交粳稻不育系177A。Using marker-assisted selection,a new dominant semi-dwarf japonica lines 177 was obtained from the BC_1F_5 population which derived from the cross using the dominant semi-dwarf mutant Y98149 as the donor and maintainer line 8204 B as the recipient.Subsequently,using the BT-type male sterile cytoplasm donor ＇ Hanfeng A＇as female parent,177 as the recurrent parent,a dominant semi-dwarf hybrid japonica rice sterile lines177 A,with stable fertility,good flowering habit and combining ability,was successfully developed.
