Abstract
Triticum timopheevii and related species T. militinae (2n=28, AtG) and T. zhukovskyi (2n=42, AmAtG), hybrids T. kiharae, T. miguschovae, the amphidiploid T. timopheevii x T. tauschii (all 2n=42, AtGD), T. fungicidum (ABAtG) and T. timonovum (2n=56, AtAtGG) were analyzed using the C-banding technique. Chromosomes of the Am and At genomes in the karyotype of T. zhukovskyi differed in their C-banding pattern. Partial substitutions of At-genome chromosomes and a complete substitution of the G-genome chromosomes by homoeologous chromosomes of an unidentified tetraploid wheat species with an AB genome composition were found in the T. timonovum karyotype. At- and G-genome chromosomes in the karyotypes of all studied species had similar C-banding patterns and were characterized by a low level of polymorphism. The comparative stability of the At and G genomes is determined by the origin and specifity of cultivation of studied species.
