The article is devoted to the study of the productivity of wheat varieties and strains depending on abiotic and biotic factors. It is determined that the yield of wheat grain depends on weather conditions of the growing season, plant height, resistance to lodging and damage by pathogens of fungal diseases. Uzhynok, Pannonicus, Emerino and Ac Meckinon varieties, Umanchanka and LPP 1314 club wheat strains have the highest yield (10.0–11.0 t/ha) and stability. The protein content does not depend on the ecological and geographical origin of the wheat variety but hybridization of Tr. Aestivum/ Tr. Spelta and Tr. aestivum/ amphiploid (Tr. durum/ Ae. tauschii) provides an increase in protein content by 23–58 %. Kokhana, Kulundynka and Pannonicus varieties and Umanchanka, Ethiopian 1, LPP 1314, LPP 2793, LPP 3118 and NAK46/12 strains form the highest and most stable protein content in grain, from 14.3 to 21.0 %. However, Pannonicus soft wheat variety, LPP 1314 strain and club wheat are characterized by the highest yield and the highest protein content with high stability.
