Wheat grain variety Bamberka and SHM 200 line differring in the content of microelements (Cu, Fe, Zn, Mn) and macroelements (P, K, Mg, Ca) were divided into 5 and 4 size fractions, resp. The largest grain showed the highest protein content. The classification of wheat grain by sieving allowed to distinguish grain streams with different contents of Mn, Zn, P, Fe and protein within one variety for a large grain size range above 3.25 and 2.2-2.5 mm.
