The physical and technological parameters of barley grain are studied on spring barley 28 samples. The reliable positive correlation (r = 0.726) between the grain density size and its glassiness indicator is determined. The possibility of barley sample division into two contrast groups differing on grain glassiness on the basis of its measured density is shown.
