摘　　要：广泰A是广东省农业科学院水稻研究所以保持系中间材料荣丰B//米31/W254为母本,具有香味的保持系中间材料天丰B/粤丰B为父本进行杂交,然后通过分子标记辅助选择具有香味且直链淀粉较低的F3代株系与印尼水田谷胞质不育系荣丰A测交,后经连续回交转育而成的优质香稻不育系。该不育系具有败育彻底、育性稳定、柱头外露率高、异交习性好、配合力好等特点,米质达部颁标准优质1级,2016年10月通过广东省种子管理总站组织的专家技术鉴定,目前已经组配出广泰优华占、广泰优粤农丝苗、广泰优736、广泰优7170、广泰优秋占、广泰优天弘丝苗、广泰优航0799等多个组合通过国家和省级品种审定。Guangtai A, developed by crossing Rongfeng A(a CMS line with the cytoplasm from Indonesian paddy rice) to the selected F3 plants from the cross of Rongfeng B//Mi 31/W254///Tianfeng B/Yuefeng B and followed by successive backcrosses, is a new aromatic indica CMS line in rice. It is characteristic of stable and complete male sterility, good flowering habits with high stigma exsertion rate, good combining ability and fine grain quality reaching the first class of high-quality rice standards issued by the Ministry of Agriculture. It was technically identified in Guangdong Province in October, 2016. The hybrids of Guangtaiyou Huazhan, Guangtaiyou Yuenongsimiao, Guangtaiyou 736, Guangtaiyou 7170, Guangtaiyou Qiuzhan, Guangtaiyou Tianhongsimiao and Guangtaiyou Hang 0799 have been successfully developed and released to commercial production by the national or provincial crop variety appraisal committees in China.
