Abstract

Aim. To establish the presence of polymorphism and differences in variants of the protein spectrum of buckwheat seed storage proteins in groups of varieties with different colors of the flower corolla. Methods. Electrophoresis using the Laemmli method in 17.5% of the separating PAAG gels, visualization and identification of the spectrum variants. Results. The common variants of the electrophoretic spectrum for all groups of buckwheat varieties and the heterogeneity of each of the studied groups of genotypes are revealed. By frequency of variants of electrophoretic spectrum between groups of varieties were detected statistically significant differences and reliable predominance of individual variants in green-flower morphotypes of buckwheat were established. Conclusions. Differences in frequency of occurrence of variants of electrophoretic spectrum in different morphotypes of buckwheat indicate the probable processes of preservation of individual adaptive alleles of genes of seed storage proteins, which occurred in populations when varieties under the pressure of breeding process.

Keywords: edible buckwheat, spare proteins, globulins, albumins, polymorphism.
