杂种一代小麦的培育研究,已成为世界上许多国家小麦育种的新课题。其主要途径是通过属间和种间杂交与回交,使一方的细胞核置于另一方细胞质之中,育成质核杂种的后代,有的能出现稳定的雄性不育性,为了方便起见,通常把此类细胞质称为雄性不育细胞质,并用以育成生产用的雄性不育系;另一方面是利用能使原有雄性不育细胞质的不育小麦恢复为 Breeding of hybrid generation wheat has become a new topic in wheat breeding in many countries in the world. The main approach is through interbreeding and interspecific hybridization and backcrossing, so that one of the nuclei placed in the other cytoplasm, breeding progeny of nuclear hybrids, and some can appear stable male sterility, for convenience, usually This type of cytoplasm is called male sterile cytoplasm and is used to fertilize male sterile lines for production. On the other hand, sterile cytoplasmic male sterile wheat is restored to
