对于植物雄性不育的遗传现象,希尔斯(Sears)在40年代曾概括为:细胞核雄性不育、细胞质雄性不育、核质互作型雄性不育三种类型,认为细胞核雄性不育是受细胞核内的不育基因控制的,没有保持系;细胞质雄性不育是受细胞质内不育基因控制的,没有恢复系;核质互作型雄性不育同时受细胞核不育基因和细胞质不育基因控制,因而可以实现不育系、保持系、恢复系三系配套。在此基础上希尔斯还提出了一个人工制造保持系的育种方案,称为“洋葱公式”。

For the genetic phenomenon of plant male sterility, Sears summarized in the 1940s as: three types of male sterility, cytoplasmic male sterility and nuclear cytoplasmic male sterility. It is considered that male sterility of the nucleus is The cytoplasmic male sterility is controlled by the cytoplasmic sterile gene and has no restorer line. The cytoplasmic male sterility is controlled by both the nuclear sterility gene and the cytoplasmic male sterility Gene control, which can be sterile lines to maintain Department, Department of three-line system. On this basis, Hills also proposed a breeding program to maintain artificial lines, known as the “onion formula.”
