水稻航天诱变育种及其机理研究的进展与展望

The Progress and Prospect on the Rice Breeding by Space-flight Mutagenesis and Mechamism

我国首创利用返地式卫星搭载植物干种子进行地面育种的工作 ,并通过近 10年的选育获得了一批性状优良的水稻新品种。对水稻航天育种工作的特点 ,育种成果 ,尤其是对水稻航天诱变育种机理研究的进展情况进行综述 ,并对水稻航天育种工作的前景进行展望。

China is the first country that started the plant breeding that the seed was carried in the space shuttle by backtrack satellite.A batch of good quality rice varieties were obtained during the last ten years.This paper generalizes advances about the character of rice space-flight breeding,and breeding production, especially the theory of the rice space-flight breeding, finally put forward to prospect of the rice space-flight breeding.
