通过将由MS基因引起的显性雄性不育(DMS)转移到不同类型细胞质的不育系中，育成了12个DMS系，并与其他类型的甘蓝型油菜杂交。在这次群体改良过程中，有16个基因被鉴定为具有恢复MS基因F1植株育性的能力。根据系谱分析，这些品系中的抑制基因可能来自澳大利亚和德国的几个基因型。在进一步的研究中，确定了不育抑制的遗传，为甘蓝型油菜显性雄性不育及其抑制是由两个显性互作基因控制的，而不是由多个等位基因控制的。
By transferring dominant male sterility (DMS), caused by the gene Ms, to genotypes with various types of cytoplasm 12 DMS lines were developed and a number of crosses made between the DMS lines and other genotypes of Brassica napus. During the course of this population improvement programme, 16 genotypes were identified as having the capacity to restore the fertility of F 1 plants with the Ms gene. According to pedigree analysis, the inhibitory gene in those lines probably originated from a few genotypes from Australia and Germany. In further studies the inheritance of the sterility inhibitory was determined, providing definite evidence that dominant male sterility and its inhibition in B. napus are controlled by two dominant interacting genes rather than by multiple alleles
