Abstract

The results of analysis of the genome formation in interspecific hybrids of Triticum aestivum with T. timopheevii are reviewed. The spectra of substitutions and rearrangements are shown to depend on the genotypes of the parental forms and on the direction of selection. The frequencies of substitutions of individual T. timopheevii chromosomes significantly vary and reflect the level of their divergence relative to the common wheat chromosomes. Some aspects of classification of the A(t)- and G-genome chromosomes are discussed.

摘要

综述了普通小麦与提莫菲维小麦种间杂种基因组形成的分析结果。结果表明，替换和重排的谱取决于亲本形式的基因型和选择方向。提莫菲维小麦单个染色体的替换频率显著不同，反映了它们与普通小麦染色体的分化程度。讨论了A(t)基因组和G基因组染色体分类的一些方面。
