针对杂交水稻两系或三系不育系易受温度等环境条件的影响，造成杂交水稻种子自交混杂的难题，浙江大学核农所作物诱变改良中心首次建立了应用核辐射技术培育带叶色标记杂交水稻不育系的技术程序。由于不育系带有易于识别的隐性叶色标记，在苗期就可以加以识别，并予以人工剔除?
For two or three lines of hybrid rice CMS susceptible to environmental conditions such as temperature, resulting hybrid rice hybrid self-confrontation problems, Zhejiang University Institute of Nuclear Crops mutagenesis improved for the first time established nuclear radiation technology to cultivate with leaves Technical Procedure for Color Marking of CMS Lines in Rice. Because sterile lines with easy-to-recognize recessive leaf color markers can be identified at the seedling stage and manually rejected.
