摘要： 以Basmati 370幼穗为起始材料，应用离体诱变技术，获得了籼稻胞质突变不育株，经测交找到保持系E49-2，并通过多代回交育成了稳定的新型不育系TRB370A。该不育系属于配子体不育型。

Abstract: The induced plants with cytoplasm mate sterility(CMS) from young panicle of Basmati 370 were obtained by in-vitro radiation. The TRB370A from Basmati 370 CMS plants by backcross for several generations and its maintainer line by tested cross were developed. According to the analysis of characteristics of genetics and pollen abortion, TRB370A belongs to a gametophyte sterile line.

Key words: cytoplasmic sterile line, in-vitro radiation, maintainer line, restorer line
