摘　　要：用安农810S、安农S-1、献党、香125S、培矮64S等多个材料复合杂交,通过自然低温条件和人工低温对育性的增压选择,经过7 a12代的定向培育,于2002年育成不育起点温度低、具有理想株型、优质的早籼型光温敏核不育系9771S,2005年通过湖南省农作物品种审定委员会审定。9771S,derived from the multiple cross of Annong 810S∥Annong S-1/Xiandang///Xiang 125S∥Xiang 125S/Pei′ai 64S,is a photoperiod-and thermo-sensitive genic male sterile（PTGMS） line with a low critical sterility-inducing temperature,ideal plant type and fine grain quality in rice.It was developed in 2002 after seven years and 12 generations of directional selection and breeding under the stress conditions of lower natural and artificial temperature.In 2005,it was certified by Hunan Provincial Crop Variety Appraisal Committee.
