摘　　要：试验结果表明：根据水稻Ｍ＿１代性状表现与Ｍ＿２代变异频率的相关性，选择一定性状的Ｍ＿２代材料留种，有减少选择世代工作量，提高筛选效率的作用。Tbe experimental results show that the amount of work for selecting generations can be de- creased and screening efficiency can be increased when M_1 materials of definite characters are selected as seedsaccording to the interrelation between Mi characters and M_2 mutagenic frequency.

关 键 词：筛选效率 辐射育种 辐射遗传 水稻
