| 摘 要： | 在中粳杂交组合“M9056 × R8018选”的F6 选种圃中，发现半矮秆突变单株。以纯合半矮秆单株为父、母本， 与稳定野生型高秆单株进行正、反杂交。种植 P1 、P2 、F1、F2 世代群体。结果表明F1 植株与半矮秆亲本基本相同， 仍然表现半矮秆。 说明该半矮秆突变材料的矮生性表达为显性， 无细胞质效应。F2 群体植株株高性状发生分离，其分离比符合一对等位基因的遗传模式，说明该半矮秆材料的矮生性表达受一对核基因控制。

| Abstract: | In F 6 generation selected nursery of medium japonica rice cross between M9056 and R8018 xuan, a semi dwarf mutant was found. Based on the analysis of the populations variation of plant height of F 1 and F 2 from reciprocal cross and its parents, it was found that the semi dwarfism of the mutant was controlled by a pair of dominant nuclear genes, its expression could not be affected by cytoplasm. |
