The content of storage proteins in the seeds of wheat species with different levels of ploidy and genomic composition was studied. It was shown that in caryopses the protein content varied by three times. Averaging the data for different species and grouping them depending on the ploidy and genomic composition did not reveal significant differences in the total protein content, but the groups of species differed in fractional composition. Diploid and hexaploid species significantly differed in the content of individual protein fractions, while tetraploid species had an intermediate values. Spelt wheat, characterized by a high content and quality of protein, is a promising species for cultivation, however, species with the A bG genomic composition are also of interest. Discriminant analysis of the data showed that the species with the AbG genome (T. timopheevii, T. militinae) differed from other groups of species in the characteristics of the caryopsis protein.
