The work was done to investigate differences in morphometric parameters of the grains of analogue-lines, that differ by the alleles of the dwarfing genes. Analogue-lines have significant differences by the parameters of the grains: length (lē) and width (dē) of the grain, area (Sē) and perimeter (Pē) of projection of the grain on the square, compactness of the grain (dē/lē). In the most cases introduction of dwarfing genes decrease grain size.
