There are highlighted the results of research in order to determine the field and laboratory resistance of the winter wheat varieties in a competitive variety testing at the National Scientific Centre Institute of Agriculture of NAAS (2016–2020) against pests, and the level of their productivity is assessed. Among the studied varieties of winter wheat, varieties with complex resistance were found: to cereal aphids, wheat thrips powdery mildew and brown leaf rust - variety Efektna; to cereal aphids, wheat thrips and leaf rust - varieties Polisianka, Pyriatynka, Krasunia Poliska, Vodohrai, Kesariia Poliska, Myroliubna, Romanivna, Pamiati Hirka, and standard Lisova Pisnia St. When varieties were grown without the use of fungicides, insecticides and growth regulators, their yield varied over the years from 2.99 t ha–1 to 10.71 t ha–1. The best varieties of soft winter wheat in terms of their productivity were identified in the northern Forest - Steppe zone, which are included in the State Register of the plant varieties, suitable for distribution in Ukraine - Kesariia Poliska (7.67 t ha–1), Pyriatynka (7.10 t ha–1), Myroliubna (7.08 t ha–1), Merezhka (6.77 t ha–1), Kraeivyd (6.71 t ha–1), Pamiati Hirka (6.61 t ha–1), Polisianka (6.51 t ha–1) and Efektna (6.36 t ha–1). Consequently, with proper selection of the winter wheat varieties, it is possible to significantly limit the harmfulness of pests and diseases, to reduce the amount of the used pesticides, to increase the grain productivity, and to improve its commercial and seed quality.
