Relationship of indicators of electrophoretic analysis of gliadin protein in different Triticum aestivum varieties with grain

Data on the electrophoretic analysis of gliadin reserve proteins of 17 Triticum aestivum land varieties developed at the Research Institute of Agriculture are presented. As a result of the study, a wide polymorphism between varieties was established. The species differ from each other in all electrophoretic components. No matter how great this difference was, during the selection process, special attention was paid to the chromosomes Gld 1A and Gld 1B and Gld 1D. The high occurrence of the block of gliadin components GLd 1D is associated with the absence of severe frosts and the fact that most of the territories belong to the arid zone. The coincidence of the blocks of components GLd 1A5, GLd 1A4 and GLd 1B1 is due to the fact that their joint presence in the genotype has a positive effect on the quality of bread.
