Based on a C-banded chromosome analysis of Triticum aestivum x T. timopheevii hybrid lines, we developed a classification of the A(t) and G genome chromosomes that agrees with the standard genetic nomenclature of T. aestivum chromosomes. Transfer of genetic material from T. timopheevii to T. aestivum involved complete chromosomes, chromosome arms, or segments. Frequencies of chromosome substitution were highest for homoeologous group 2 and lowest for group 4. Moreover, B(G) substitutions were frequent compared to A(A(t)). The pattern of chromosome substitutions and rearrangements were unequal and depended on the genotype of the parental T. aestivum cultivar.
基于对普通小麦与提莫菲维小麦杂种后代的 C 带染色体分析，我们对 A(t)和 G 基因组染色体进行了分类，这一分类与普通小麦染色体的标准遗传命名法是一致的。从提莫菲维小麦向普通小麦的遗传物质转移涉及完整的染色体、染色体臂或片段。同组染色体 2 的染色体替代频率最高，而 4 组最低。此外，与 A(A(t))相比，B(G)的替代更为频繁。染色体替代和重排的模式是不均等的，并且取决于亲本普通小麦品种的基因型。
