利用伽玛射线对粳稻品种中花11进行辐照，以诱导广泛的形态突变体，为水稻功能基因组研究提供基础材料。辐射第1代单本移栽并实行单株收获；辐射第2代（M2）播种1万个家系，自苗期开始至成熟期各个生育阶段从中独立选获各类形态突变体540个；经M3复选获得包括叶、茎、穗和育性变化等各类突变体431份。统计结果表明，形态性状的突变频率为5.1%。

Screening and Character ization of Mutants Induced from Zhonghua 11 ( Oryza sativa L.subsp. j ap onica ) by Irradiation

T he japonica r ice ( Oryza sativa L . ) variety Zhonghua 11, developed by anther culture technology, was irradiated by gamma rays to induce extensive mutation for functional genomics research use. M1 generation was transplanted and harvested by each single plant. Ten thousand families of M2 generation were planted. From seedling stage to maturity stage in M2 generation, 540 morphological mutants were isolated. In M3 generation 431 mutants including leaf, stalk, panicle and sterility variations were identified and selected repeatedly. T he statistic analysis indicated that the mutation frequency of morphological character was 5. 1%.
