1988～1990年分析了农垦58S及其转育的粳型核不育系31111S分别与3个粳稻品种杂交获得的6个组合F_1、F_2、BF_1及部分F_3家系在武昌自然长光照下的育性表现.结果表明各组合正、反交F_1均为可育,正、反交F_2群体呈现一致的育性分离,农垦58S和31111S的不育性皆受核内主基因控制,不表现细胞质效应,其不育类型属孢子体不育;对分离世代群体育性进行适合性检验,农垦58对农垦58S和31111S的不育性的恢复,具有一对显性主效基因的作用,而鄂晚4号和武复粳对其均具有两对显性主效基因的作用;等位性测验表明31111S与农垦58S的光敏核不育基因等位.
The fertility of 6 combinations F_1, F_2, BF_1 and some F_3 families of Nongken 58S and its japonica CMS line 31111S crossed with 3 japonica varieties from 1988 to 1990 were analyzed. The results showed that the positive and negative F_1 of each combination were fertile, the positive and negative F_2 populations showed the same fertility segregation, and the sterility of Nongken 58S and 31111S was controlled by the major genes in the nucleus, The sterility genus was sporophyte infertility. The suitability test of the segregation generation population fertility showed that Nongken 58 had a dominant dominant gene effect on the recovery of sterility of Nongken 58S and 31111S, And Wu-fu-jing had two pairs of dominant-effect genes. Allelism test showed that the alleles of the light-sensitive genic male sterile genes were 31111S and Nongken 58S.
