Abstrakt: The somatic chromosomes ofTriticum timopheevi and those of two varieties ofT. aestivum, “Chinese Spring” and “Bezostaya-1”, have been identified by a Giemsa staining technique. The data suggest thatT. timopheevi and tetraploid wheats had a common ancestor from which their genomes differentiated due to chromosomal aberrations and the increase of heterochromatin in the chromosomes of theT. timopheevi G-genome. The differences between the chromosomes of the AB and AG genomes result in substitutions and large translocations between these chromosomes in interspecific hybrids.
