摘　　要：本S是以光温敏核不育系广占63S为母本与保持系天丰B杂交,F3代选择优良不育单株为母本与天丰B回交,后经多代目标性状定向选择而育成的新水稻温敏核不育系。该不育系综合农艺性状优良,不育起点温度较低,开花习性好,异交结实率高,配合力强,2018年7月通过广东省技术鉴定。Ben S,derived from the cross between Guangzhan 63 S,a photoperiod-and thermo-sensitive genic male sterile(PTGMS)line,as the female and Tianfeng B,a maintainer line,followed by a backcross of its desirable male sterile F3 plants to Tianfeng B and years of directional selection on target traits,is a new TGMS line in rice.It has excellent comprehensive agronomic traits,low critical sterility-inducing temperature,good flowering habits,high outcrossing and seed-setting rate and strong combining ability.In July,2018,Ben S was technically identified in Guangdong Province.
