糖甜菜三倍体类型的小孢子发生糖甜菜三倍体小孢子发生特点和结实性信息的重要性,在于第一,三倍体可用来获得三体,三体是遗传分析的手段;第二,它们是育种上利用的四倍体群体中,分布广泛的混杂物。三倍体结实性及其子代倍数性组成的资料,可以做为四倍体群体中,混杂危险程度的予

Sugar beet triploid type microspores occur Sugar beet trigeminal microspore Occurrence and the importance of the information of seedability, is that the first, triploid can be used to obtain trisomy, trisomy is the means of genetic analysis; the second , Which are widely distributed mixtures of tetraploid populations utilized in breeding. Triploid solidity and its progeny multiples of the composition of the information can be used as a tetraploid population, mixed with the degree of risk to
