Here are presented the results of the analysis of available variety assortment and grain yields of different varieties of spring small cereals: barley, oat, wheat and triticale towards their agroecological genetic flexibility and grain productivity in changing hydrothermal conditions. We marked the varieties, which characterized by high genetic potential of grain yield in a wide range of variation of average air temperatures and conditions of water provision. In the conditions of the Northern Steppe of Ukraine in 2011-2015 the high crop yields (3.60-3.64 t/ha) formed varieties of spring barley: Galaktyk, Statok and Vsesvit. Among the oats varieties the best crop yields (3.34-3.46 t/ha) provided Iren and Spurt and it was specified as almost the best barley variety according to this indicator. The Spadschyna and Kharkivs’ka-39 varieites had the best crop yield among the spring wheat (1.74-1.81 t/ha). Spring triticale had the lowest grain yield among spring crops (1,07-1,21 t/ha) due to the low weight of 1000 grains and insufficient grain yield per ear.
