摘 要 ：60Co-γ射线诱发的8个釉型温敏核不育系水稻叶色突变系可分为三种类型，即叶色突变高温表达型、低温表达型及温钝型。对温钝型3个突变系研究发现，该性状由单一隐性基因控制，其农艺性状除LCM6外与对照2177s相似或有所改观，育性转换特性和配合力也与对照相仿，对杂种优势无细胞质负效应。与杂交种“汕优63"混合播种时，叶色

Abstract:8 strains of leaf color mutants induced by 60Co-γ irradiation from Thermo-sensitive genic male sterile line 2177s，were obtained. According to differences in their response to temperature，these lines were classified into three types(Table 1)，namely those whose mutated leaf color traits expressed
