六倍体小黑麦与普通小麦的杂种一代具有AABBDK组合,可以形成不同组成类型染色体的多样化配子,而杂种一代自交若干代后将出现一批具有由不同染色体组成的植株,从普通小麦到典型的六倍体小黑麦,并产生具有DK混合染色体组成的中间类型,即异源易位系,代换系和附加系。 为了对上述的杂种后代进行细胞学鉴定,我们设计了一个较简便的方法,能较准确地进行鉴定,可供同行参考借鉴。 The hybrid generation of hexaploid triticale and common wheat has the combination of AABBDK, which can form diverse gametes with different constitutive types of chromosomes, while the hybrid generation will produce a group of plants with different chromosomes from self-generation generations, To typical hexaploid triticale and produce intermediate types with the DK mixed chromosome composition, namely heterologous translocations, substitution lines and additional lines. In order to identify the above-mentioned hybrid progenies for cytology, we designed a simpler method that can be more accurately identified for peer reference.
