An electrophoretic investigation of the glutenin subunits and gliadin components in F4 progenies between the hexaploid wheat (Triticum aestivum L. cv. Bezostaya 1) and the wild tetraploid wheat (Triticum turgidum var.dicoccoides Körn) is carried out. The possibility of inserting subunits and components of Glu B1, Glu B3 and Gli B1 loci fromT. dicoccoides in F4 progenies ofT. aestivum is investigated. For this purpose parental forms with different allelic variants in these loci are chosen. It is established cytologically that the chromosomal number of progenies is 42. Genotype classes and the frequency of progenies are analyzed for which we judge by the phenotype manifestation of the allelic variants of the loci investigated. Different frequency of the transfer of subunits and components of Glu B1, Glu B3 and Gli B1 loci fromT. dicoccoides in the hexaploid wheat genome is established and it is connected with the disposition of the loci on chromosomes arms.
