Due to the high demand for zucchini as a raw material for the canning industry, its active cultivation is observed in the Astrakhan Region. Farms engaged in zucchini cultivation are concentrated in the Volga River Delta. This region is characterized by challenging agroclimatic conditions, caused by critically high summer temperatures, heavy rains, autumn fogs, etc., which influence the assortment and cultivation characteristics of this crop. This article presents the results of an experiment to comparatively characterize new promising zucchini hybrids grown on alluvial soils of the Volga River Delta. The experiments were conducted in 2024. The zucchini hybrids studied were domestic (Arthur F1; Kasatik F1) and foreign (Inessa F1; Kordelia F1; Sherkhan F1). A study of the productivity characteristics of zucchini hybrids revealed the highest yields in the Arthur F1 (96.21 t/ha), Inessa F1 (109.41 t/ha), and Sherkhan F1 (112.07 t/ha) varieties, with high marketability (98%).
