Influence of varietal characteristics and growth factors on the quality of Natsional’na and Polis’ka 90 winter wheat varieties was studded. Grain of Polis’ka 90 variety was distinguished by considerable variability of grades, however, the grain of Natsional’na variety was exposed to greater number of growth factors. Grain unit index influenced the grain quality grade of Natsional’na 90 determination, gluten quality and protein and fiber content indices influenced that of Polis’ka 90. It was established that the grain of Polis’ka variety in most of the cases had higher grades of quality than Natsional’na variety. The highest grades of quality were registered for the seed harvested after perennial grasses, namely 2d and 3d grades of Natsional’na variety and the 1t and the 2d for Polis’ka 90 variety. Greater grades of quality were registered for the seed grown according to intensive and ecological farming systems (generally, grades 1 to 3), while the lower grades were inherent to biological system (generally, grades 3 to 5).
