Evaluation of plant breeding material, based on protein markers, gives an opportunity to perform rapid and reliable selection and control the transfer of desired traits from parents to their progeny. A search for new and stable protein markers is needed to identify genotypes with high grain quality. Such storage proteins in wheat as glutenins have been studied profoundly enough. Full characterization of individual protein fractions and components can be found in many scienti fic publications, while studying genetic patterns of protein accumulation in the grain of different wheat cultivars and using high-molecular-weight (HMW) and lowmolecular-weight (LMW) glutenin subunits (GS) for genotype identi fication remain high in the research agenda. This is a comprehensive review of scienti fic publications about the structure and molecular organization of glutenins and a comparative analysis of 22 research papers about the degree of their effect on grain quality indicators: SDS-sedimentation volume (ml), grain/ flour protein content (%; 14% m.b.; 12,5% m.b.), mixing time (min), mixing tolerance (min; mm), bread loaf volume (cm3; ml), dough strength (10 -4 J), and P/L ratio. As a result of reviewing, the best alleles (subunits) of glutenin were identi fied, namely: Glu-A1а, Glu-B1(h, f, b), Glu-D1d, Glu-A3d, and Glu-B3d.
