变异是选择的基础,如果提高诱变效率是辐射育种工作急待解决的重要议题。辐射杂种材料则是当前提高诱变效率的一项引入注目的重要研究内容。关于Y射线辐照小麦杂种材料提高诱变效果的研究国内已有一些报道,本试验旨在探索γ射线辐照水稻杂交材料对提高诱变效果的作用。材料和方法1981年春,粒选广陆矮四号、湘矮早九号(以下分别简称广四、湘九)和竹系26原种,
Mutation is the basis of choice, if the improvement of mutagenesis efficiency is an urgent issue to be solved radiation breeding. Radiation hybrid materials are an important and important research topic to improve the mutagenic efficiency. There are some reports about the effect of γ-ray irradiation on wheat hybrid materials to improve the mutagenic effect. The purpose of this experiment is to explore the effect of γ-ray irradiation of rice hybrid materials on improving the mutagenic effect. Materials and Methods In the spring of 1981, grains of Guanglu Dwarf No. 4 and Hunan Dwarf No. 9 (hereinafter referred to as “Guangsi” and “Xiangjiu” for short)
