The content of protein in the introgressive lines of bread winter wheat, created by repeated crossing of amphiploids, primitive lines or collection samples with modern varieties of soft winter wheat was studied. The breeding lines with alien gene complexes of high values of thousand-kernel weight, protein content and morphological characters, devoid of negative qualities of wild species, characterized by high productivity, adaptability, tolerance to low agrophones, high quality, which may be of interest for further breeding work were isolated. The influence of different terms and doses of nitrogen fertilizers on the accumulation of nitrogen and sugars in the green mass of bread winter wheat has been studied. Varietal features of nitrogen and sugar content accumulation depending on the type, dose and terms of nitrogen fertilizer application are revealed. The method of electrophoresis of wheat grain gliadins for identification of wheat-rye translocations 1AL.1RS and 1BL.1RS was developed. The collection of bread winter wheat varieties (30 varieties) was analyzed for the presence of these wheat-rye translocations. The method of electrophoresis of barley root superoxide dismutase for identification of enzyme isoforms Sod S1 and Sod S2, which can be used to estimation of adaptive status of barley varieties were developed. The collection of barley varieties (70 varieties) for the presence of these superoxide dismutase isoforms was analyzed. Distinct genotypic differences in the component composition of root superoxide dismutase in the studied barley genotypes (presence of genotypes with Sod S1, Sod S2 and polymorphic genotypes [Sod S1 + Sod S2]) were revealed. The obtained results can be used in the breeding process at the creation a new source material with high adaptive properties. The methodical recommendations "Estimation of selection material of grain crops on food and fodder value on biochemical indicators" are published.
