Aim. Determine the influence of ecological and geographical factors of variability on the yield of modern winter wheat varieties created at the Institute of Agriculture of the National Academy of Sciences of the Russian Academy of Sciences. Methods. Field, laboratory and analytical research. Field research was carried out under the conditions of monitoring surveys according to the methods of determination in various points of studying the varietal diversity of winter wheat. Results. Winter wheat varieties Victoria Poliska with a yield of 7.6 t/ha, Katrusya Poliska 6.5 t/ha, Kesaria Poliska and Zemlerob each 6.2 t/ha, Fortetsia Poliska 5.87 t/ha, Pyriatynka 5.8 t / ha. Accordingly, the standards of foreign reeding Skagen 6.1 t/ha, Samurai 5.57 t/ha, Ukrainian selection Lisova Pisnia 4.87 t / ha. For 2020-2022, in the selective crop rotation of the NSC «IZ NAAN» the best varieties of winter wheat in terms of yield Zemlerob, Effectna (6.55 t/ha each), Kesaria Poliska (6.51 t/ha), Fortetsia Poliska (6, 39 t/ha), Pyryatinka (5.96 t/ha), Katrusya Poliska (5.95 t/ha), the standards of foreign selection Skagen 6.1 t/ha, Samurai 5.57 t/ha, Ukrainian selection Lisova Pisnia 4.87 t/ha. For 2020-2022, in the selective crop rotation of the NSC «IZ NAAN» the best varieties of winter wheat in terms of yield Zemlerob, Effectna (6.55 t/ha each), Kesaria Poliska (6.51 t/ha), Fortress Poliska (6.39 t/ha), Pyryatinka (5.96 t/ha), Katrusya Poliska (5.95 t/ha), respectively, the standards of foreign selection Samurai (5.49 t/ha), Kolonia (4.56 t/ha) Skagen (4.31 t/ha) and Ukrainian selection Lisova Pisnia (4.90 t/ha). Conclusions. So, modern varieties of winter wheat Viktoriya Poliska, Kraevyd, Fortetsya Poliska, Katrusya Poliska, Kesaria Poliska, Zemlerob, Efektna, Ivanna Poliska, Spivanka Poliska, Lyubito, Pamyati Hirka, Vodogray are a guarantee of increasing the productivity of winter wheat in conditions of climate change.
