摘　　要：朝湘A是湖南省水稻研究所用新香B与自育材料海2辐杂交F4代与中间材料泸香618B/玉香B的F4株系复交,自交加代至F4代,再与新香A杂交并连续回交选育而成的野败型优质三系不育系。该不育系异交习性较好,米质优,配合力强,所配组合熟期早,于2022年3月通过湖南省农作物品种审定委员会技术鉴定。Chaoxiang A,derived from crossing Xinxiang A to the selected plants from the F4 population of(Xinxiang B/Hai2fu)F4/(Luxiang 618B/Yuxiang B)F4 and followed by successive backcrossing over years,is a high-quality WAtype CMS line in rice developed by Hunan Rice Research Institute.With the characteristics of high outcrossing rate,good grain quality,high combining ability and early maturity of F1 hybrids,it was technically identified by Hunan Provincial Crop Variety Appraisal Committee in March 2022.
