The glume tip color and leaf edge color of F 1 and F 2 derived from YiDS(purple glume tip and green leaf edge)/indica rice(green glume tip and green leaf edge) were studied.
对无色叶缘无色稃尖的籼型材料与宜DS(无色叶缘紫色稃尖 )杂交F1及F2 稃尖和叶缘颜色的调查结果分析表明 ,紫色稃尖对无色稃尖为显性 ,符合 1对基因控制的遗传模式 ;控制叶缘颜色的 2对基因中的其中 1对可能为稃尖色泽控制基因 另外 ,本试验进一步确证认为籼、粳不同类型的材料在控制叶缘颜色的遗传基础上存在差异 ,其中叶缘无色的粳型材料中不存在显性互补基
Crossing Yids, a rice with short day low temperature induced male sterile(SDLTR), withsome indica rice varieties as male parent, the F1s were all purple color no matter how the leaf edge colorof male parent was.
短光低温不育水稻宜DS本身叶缘无色,与不同籼型父本杂交,无论父本的叶缘为紫色或无色,其F1均为紫色,这用于真假杂种的鉴别是一个很好的标记,经初步分析后认为,宜DS叶绿颜色的遗传符合两对基因控制的显性互补作用模式;用无色籼型父本与宜DS杂交,F1组合间叶缘颜色存在深浅差异;用粳型父本与之杂交,F1表现为无色,原因待分析。
