Abstract


As a result of screening of the allelic composition of genes associated with baking properties, a significant genotypic variety of forms of allocytoplasmic spring wheat (ATSGG) from the ATI PFUR collection was established. In addition to the altered forms, 15 genotypes were isolated as a result of recombinations and introgression, in the genome of which the presence of a allel of wild type Wx-B1a (primer 4F / 4R) was detected. Analysis of the content and quality of gluten in these forms of ACPG made it possible to differentiate these genotypes according to their functional characteristics, which are related to baking properties. The amplitude of the differences in the genotypes of the ACPG in terms of the mass fraction of gluten is from 21.7% to 37.8%, the quality of gluten according to the IDK parameters in the majority of the studied genotypes of the I-st group. The genotypes of the category of strong wheat are of particular value: No. 24 (cytoplasm T. timopheevii), in which the mass fraction of gluten is 37.8% (class of super-strong wheat), and also genotypes of the 1st class, in which the gluten content is not less than 32%, and the quality of gluten is not lower than the I-st group (IDK - 43-77 units.). These are genotypes No. 25 (the cytoplasm of T. timopheevii) and No. 29 (the cytoplasm of T.aestivum L., as a result of backcrossing). To the category of strong wheat of the 2nd class (mass fraction of gluten is not lower than 28%, and the quality of gluten is the I-st group), four genotypes are classified. The category of valuable wheat of the 3rd class includes two genotypes, in which the mass fraction of gluten is not less than 25%. However, the quality of gluten in these genotypes is not II-th group, but higher - it corresponds to the I-st group. Genotypes with a specific combination of the mass fraction of gluten characteristic of strong and valuable wheat, with the qualitative characteristics of gluten of the I-th group, expand the range of their intended use in the production of bakery products.
