当前,提高糖甜菜生产率的育种方法,主要是在二倍体水平,或在染色体组的多倍体水平上,创造显示杂种优势的杂交种。如果只谈多倍体类型糖甜菜的话,就是在生产中获得最广泛推广的三倍体杂种。显然,这并不降低糖甜菜同源四倍体的意义,因为同源四倍体是获得三倍体杂种的成分,是形成杂种种子的基本材料。文献中广泛记载了同源四倍体和三倍体的 Currently, breeding methods to increase sugar beet productivity are mainly hybrids that show heterosis at the diploid level or at the polyploid level of the genome. If you talk about polyploid sugar beet only, it is the most widely used triploid hybrid in production. Obviously, this does not reduce the significance of autotetraploid sugar beet, because the autotetraploid is to obtain triploid hybrids, is the formation of hybrid seeds of the basic material. Homologous tetraploids and triploids are well documented in the literature
