前言甜菜雄性不育性的最初研究报告,是由 Archimowitch 提出的。其后,关于这种现象的详细的遗传和育种学的研究,是由以 Owen 为首的许多研究者所进行的。在这里所讨论的雄性不育,是细胞质雄性不育性,它是根据细胞质基因同改变它的两对遗传基因的相互作用而发现的。即把正常的细胞质当作 N,雄性不育的细胞当作 S,再把两对改变遗传基因当作 X、Z。具有正常细胞质 N 的不管改变遗传基因的组合如何全部是可育的,其中特别是在纯隐性中具有改变遗传基因的个体,即遗传基因型为 N_(xxzz)的被称作 O—型,为维持雄性不良的授粉系本,就是保持系。另一方面具有不育的细胞质 S,在纯隐性中具有改变遗传 Preface The first report on the male sterility of sugar beet was presented by Archimowitch. Since then, detailed genetic and breeder studies on this phenomenon have been carried out by many researchers headed by Owen. Male sterility, discussed here, is cytoplasmic male sterility, which is found on the basis of the interaction of the cytoplasmic gene with two pairs of genes that alter it. That the normal cytoplasm as N, male sterile cells as S, and then two pairs of genetic changes as X, Z. Regardless of the genetically modified combinations with normal cytoplasm N are all fertile, in particular individuals with altered genes in purely recessive, ie genotype N_ (xxzz) are referred to as O-forms, In order to maintain the poor male pollination system, is to maintain the Department. On the other hand, cytoplasm S, which has sterility, has a genetic alteration in pure recessiveness
