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。

Abstract: 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.

Key words: hybrid rice, indica, photosensitive male-sterile line, breeding
