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 At- and G-genome chromosomes are discussed.
