Aim. Identification of new winter wheat breeding material developed in Kharkiv by electrophoretic patterns of storage proteins to select the most promising lines. Methods. Protein fractionation was performed by APAG- and SDS-electrophoresis. Results. The genotypes of winter wheat samples of the competitive variety trial at seven storage protein loci Gli-A1, Gli-B1, Gli-D1, Gli-A3, Glu-A1, Glu-B1, Glu-D1 were studied. We identified eight alleles at the Gli-A1 locus, seven at Gli-B1, five at Gli-D1, four at Gli-A3, five at Glu-B1, three at Glu-A1, and two at Glu-D1. Most of the identified alleles are typical for Ukrainian winter wheat varieties. Along with them, theree were lines with introgressed alleles marking for the wheat-rye translocations 1AL/1RS and 1BL/1RS. The biotype of the line Erythrospermum 484-19 carries an introgressed allele from Ae. tauschii at the Gli-D1 locus. Conclusions. According to field and laboratory trials of samples, there were neither significant advantages nor disadvantages of lines with wheat-rye translocations compared to lines without translocations (typical for the East Forest-Steppe zone). The promising line of the use of the 1AL/RS or 1BL/RS translocations (carrying disease resistance genes) is their coupling with the allele Glu-B1al associated with high grain quality.
