HS-57为高粱两用不育系,对其雄性不育的不育性和恢复性研究表明,HS-57在晋中盆地的育性表现,不同年份存在差异。其不育性的恢复受两对等位显性基因控制。A1类型保持系不能恢复其育性,A2类型保持系和恢复系对其育性表现恢复。
HS-57 is a sorghum dual-use sterile line. The male sterility and restorative of HS-57 showed that fertility of HS-57 in Jinzhong Basin was different in different years. The sterility recovery is controlled by two pairs of alleles dominant genes. Type A1 maintainer could not restore its fertility, Type A2 maintainer and restorer restored its fertility.
