Abstract	The investigations included two cultivars and 8 simple and backcross interspecies rye ( Secale sp.) hybrids differing in resistance to powdery mildew [ Erysiphe graminis ], brown rust [ Puccinia recondita ] and sprouting. Experimental material consisted of the seeds of plants tolerant and non-tolerant of N and K deficiencies, selected from above-mentioned rye populations. The usual SDS-PAGE electrophoresis of storage proteins was used for determining genetic differences between them. The results showed genetic differences between the tested rye genotypes. Marked differences in protein structure, shown in the presence of polypeptides specific for each genotype, were found
