在选育多倍体甜菜的全过程中,从选择稳定的四倍体亲本类型到测定杂种组成成份,都必须应用细胞学方法快速而准确地测定甜菜植株的倍数性。即使多倍体品种育成之后,在良种繁育和生产过程中,也离不开倍数性的测定。在奥地利和波兰,国家立法规定,在普通多倍体品种中三倍体和四倍体数量不得低于60%;有的要求更严格,主张仅是三倍体类型所占比例为60%以上。因此,不仅育种研究单位,而且在原种站和采种站,都应该掌握测定甜菜倍数性的细胞学方法。
In the selection of polyploid beet throughout the process, from the selection of stable tetraploid parental type to determine the composition of hybrids, cytological methods must be used to quickly and accurately measure the fold of sugar beet plants. Even after polyploid breed into breeding, breeding and production in the breeding process, but also inseparable from the multiple determination. In Austria and Poland, national legislation stipulates that the average number of triploidy and tetraploidy in common polyploid varieties should not be less than 60%; some require more stringent claims that only the triploidy types account for more than 60% . Therefore, not only breeding research units, but also in the original species and seed collection stations, should grasp the determination of beetle multiplicity of cytology methods.
