利用育性基因与农垦58S等位,但育性转换特性和光周期反应有显著差异的两个籼型光敏核不肯系间杂交,杂交后代在同一选择方法下,世代间、同一世代株系间育性表达差异甚大,但能筛选出育性表现优于双亲的株系,表明了光敏核不育基因间互作的复杂性和强化长日低温、短日高温选择压对选育温度钝感的籼型光敏核不育系的重要性。从籼S/籼S的入选率和选育效果看,此方式是选育育性稳定的籼型光敏核不育系较好的一种杂交方式。
Two indica type photosensitive kernels with significant difference in fertility conversion and photoperiodic response were not crossed between fertility genes and Nongken 58S alleles, and the progenies of hybrid progenies were cross-fertilized under the same selection method, between generations, between the same lines Fertile expression is very different, but can screen out better than the parental lines of fertility, indicating that the photosynthetic male sterile gene interaction between the complexity and strengthen long-day low temperature, short-day high temperature selection pressure on breeding temperature insensitive Importance of Indica Photo-sensitive Genic Male Sterile Lines. In view of the selection rate and breeding effect of indica S / indica S, this method is a better way to select indica-type photo-sensitive genic male sterile lines with stable fertility.
