| 摘 要： | 采用辐射诱变、杂交及逆境温度筛选相结合的综合育种方法，成功育成了辐恢838及其衍生恢复系辐恢718、辐恢305、中恢218、绵恢3728、糯恢1号等12个恢复力强、配合力高、抗逆性好的恢复系。利用这些恢复系与野败、冈型、D型、印水型、夜公型等胞质不育系组配育成的43个组合，先后通过了国家或省农作物品种审定。这些品种在大面积种植过程中表现出结实率高、较耐低温冷害和高温热害、适应性广、高产稳产的特点，累计种植面积4000万hm2 以上。其中II优838是继汕优63以后我国应用时间长、种植面积较大的著名品种。2005年成为国家籼稻区域试验对照组合，也是我国近年来主要的出口越南东南亚等国家的杂交水稻品种。 |

| Abstract: | Fuhui 838 and its derivative restorer lines(Fuhui 718,Fuhui 305,Zhongfu 218,Mianhui 3728,Nuoyou 1...)have the ability of strong restoring,high combining,and good resisting,which were bred and released by combined techniques of radiation-induced mutation,polymerization hybridization,and temperature tolerance screening.At present,about 43 combinations were registered and released to commercial production,the series of combinations present high seed setting rate,good tolerance to chilling and heat stress,wide ... |
| Keywords: | hybrid rice radiation-induced mutation Fuhui 838 derivative restorer lines adaptability breeding and utilization |
