摘　　要：以P88S与湖农5S-3杂交,经过8年10代系统选育,在第七代盛夏低温初次出现光敏株,第九代割蔸再生再次出现光敏不育株,第十代获得稳定的不育系,命名为珈1S。该不育系具有育性稳定、耐肥抗倒、高异交率、高配合力等特性,应用前景广阔。Jia1S,a photosensitive two-line male-sterile,middle-season indica line,was developed through systematic selection method by using Yiling P88S cross Hunong 3S,after 8 years/10 generations,a photosensitive plant was detected at 7th generation low temperature at summer,again detected at 9th generation regrowth,after back crossing with Ben15,a stable photosensitive two-line male sterile line was developed and named Jia1S.It has stable fertility,fertilizer tolerance,logging free,high outcross and match.It has great potential for makketing and agriculture industry.
