摘　　要：用300Gy^60Coγ射线处理湘早籼13号／香2B的F2代干种子，经多代选育，育成了优良早籼水稻新品系124，与株IS配制成杂交组合“株两优124”，在湖南省预试、省区试中表现产量高（约8000kg／hm^2），熟期适宜，生育期109d左右，比对照金优402短2～3d，且米质较好，具有较大的生产潜力。A early indica rice variety ＂124＂, which derived from dry F2 seed of the cross ＂Xiangzaoxianl 13/Xiang2B＂ treated with ^60Co γ-rays irradiation of 300Gy, were successfully bred after several generations selection. A new two-lines cross ＂Zhuliangyou 124＂ was bred, whose male parent was ＂124＂ and female parent was ＂Zhu 1S＂. It appears a higher yield （about 8000kg/hm^2 ） in preparatory and regional experiment in Hunan. The growth period of ＂zhuliangyou 124＂ is about 109 d, which is 2 - 3 d shorter than that of CK ＂Jinyou 402＂. Moreover, ＂Zhuliangyou 124＂ has a good rice quality and higher production potential.
