This article presents the results of an ecological trial of sunflower hybrids on ordinary chernozem soil in the southern zone of the Rostov Region. Based on the results of the study, sunflower hybrids were identified that demonstrated high productivity and good seed quality under the prevailing weather conditions. The resistance of the hybrids to environmental stress factors was assessed, and the most adaptive and flexible ones were identified. Hybrids that exhibited the best parameters of economically valuable traits and provided the highest oil yield per hectare were recommended for agricultural production.
