| 摘 要： | 对粳稻品种合系4号诱变产生的5个低直链淀粉突变体YM1、YM2、P152、P153、P154进行了遗传分析。这5个低直链淀粉突变体的低直链淀粉含量均受一对隐性基因控制,并具等位性,且与wx位点不等位。直链淀粉含量较高的YM1（10.50%)与其他4个低直链淀粉含量突变体杂交F2存在着由一对等位基因控制的分离现象，直链淀粉含量较高对较低表现为显性。

| Abstract: | The genetic analysis of the low amylose content mutants YM1, YM2, P152, P153, and P154 induced fromjaponica rice Hexi 4 was cartted out. The recessive genes conditioning lower amylose content in the low amylose content mutants are alleies each other and nonallelic to the wx locus. The segregation of F2 of the crosses between low amylose contentmutants and YM1 with higher amylose content (10. 50%) fits the inheritance mode of single gene. The gene conditioninghigher amylose content is dominant to lower amylose content. |
