摘　　要：籼型光温敏核不育系F136S是以丰6S为母本、Y58S为父本杂交,经过6 a11代系谱选择育成。该不育系不育起点温度较低、育性稳定、败育彻底、株型紧凑、抗性较好、米质较优,2017年通过安徽省农作物品种审定委员会组织的技术鉴定。介绍了F136S的选育过程、特征特性、配组应用和繁殖制种技术要点。Derived from the cross of Feng 6S(as the female) and Y58 S(as the male),F136S is a new photo-thermosensitive genic male sterile(PTGMS) line in indica rice.It was developed through six years and 11 generations of directional selection under the conditions of low temperature stress.F136S showed the characteristics of low critical sterility-inducing temperature,complete and stable male sterility,compact plant type,good blast resistance and fine grain quality.It was technically identified by Anhui Provincial Crop Variety Appraisal Committee in 2017.The breeding process,characteristics,F1 hybrids and key technical points for the multiplication and hybrid seed production of F136S were introduced in this paper.
