The analvsis of polymorphism of such genes as Glu-A1x, Glu-B1x and Glu-B1y, Glu-D1x and Glu-D1y controlling synthesis of storage seed proteins (glutenins) was conducted in 45 variety samples of winter wheat (Triticum). Probable bread making qualities of the studied lines were estimated. The test results of Belarusian wheat samples showed that among them, a high share of allels in Glu-A1 and Glu-B1 loci influencing the bread-making qualities negatively, and d allel in Glu-D1 locus contributing positively to flour quality was observed. As a result of the researches conducted, genotypes containing favorable combinations of the alleles of high-molecular-weight glutenins were isolated. 4 variety samples with the highest indices of bread-making (qualities (10 points) were found out. The lowest overall bread- making estimate was in the variety samples in which parents were only West-European varieties, such as STH 729, STH 735, Kubus, Kriss, STH 583, STH 1198, Kontur, Kornet, and as well as when Belarusian varieties with low bread-making qualities (Schara and Garmoniya) were used.
