摘要
为了加快选育谷子光敏雄性不育系,对其性状遗传规律进行了研究。结果显示,育性、叶鞘色、穗型、出苗至抽穗天数属于质量性状遗传,受1对基因控制;叶舌、花药颜色属于质量性状遗传,受2对互补基因控制;刚毛属数量性状遗传,在F2表现长、中、短3种性状。
To accelerate breeding of the light sensitive sterile line, we had studied the inheritance of millet main characteristics. The results were the following： fertility, leaf sheath color, panicle tape and emergerce to heading days are all qualitative characters controlled by one pair of genes and were separated in F2 generation according to Mendelian rules 3∶1; leaf tongue and anther colour are all controlled by two paris of complementary genes and separated in F2 generation according to Mendelian rules 9∶ 7; setae is of quantitative trait and shows long 、medium and short three kinds of traits in F2.
