SUMMARY. Diversity of Ukrainian winter common wheat varieties was studied with respect to the storage protein loci Gli-A1, Gli-B1, Gli-D1, Glu-A1, Glu-B1, Glu-D1, Gli-A3, Gli-B5, and Gli-A6 (362 varieties) and markers for the Lr34/Yr18/Pm38/Sr57/Bdv1 gene conferring moderate resistance to a number of biotrophic pathogens, the Tsn1 gene for sensitivity to the toxins A of the necrotrophic fungi Pyrenophora triticirepentis and Stagonospora nodorum, the Tsc2 gene for sensitivity to the toxin B of P. triticirepentis, and the TDF_076_2D gene for moderate resistance to Fusarium head blight (181 varieties). Significant differences in frequencies of alleles at these marker loci between groups of varieties developed in different soil and climatic zones were revealed. The retention of a set of predominant alleles of a certain zone in different periods of breeding was confirmed. At the same time, the appearance of new allele associations in the groups of varieties of the Steppe (in particular Gli-A1g and Glu-B1al) and the Central Forest-Steppe (1AL/1RS and Glu-B1d) in the last two decades has been noted. Nonrandom associations between alleles of disease resistance genes as well as alleles of disease resistance genes and storage protein alleles were revealed.
