The paper presents the results of the study of sunflower hybrids breeding FSBSI "FASC of South-East" in the period 2019-2022, which were evaluated according to the following indicators: oilseed yield, 1000-seed weight, oil content and oil yield per unit area. It was found that the oilseed yield of the standard sunflower hybrid YuVS 3 varied in the range of 1.85-5.67 t/ha, the experimental hybrids - 1.35-3.68 t/ha in the years of research. On average over the years of research, the highest yield under factor A (hybrid) was found in hybrid PG 16u×966 (3.10 t/ha), 1000 seeds weight in hybrid YuVS 3 (57.12 g), oil content 50,0 % and higher in hybrids PG 32×966, PG 32×50, PG 3116×ATI, PG 16u×966, oil yield per unit area in hybrid PG 16u×966 (1.46 t/ha). For factor B (year), the hybrids formed the highest average yield in 2022, 1000 seed weight in 2019, oil content and oil yield in 2020. The greater influence on the variability of the trait "oil seeds yield" was exerted by mutual influence of the factors AB (46,6%), mass of 1000 seeds - factor A (38,0%), oil capacity and oil yield - factor B (59,9% and 47,7%, respectively). Zhivotkov adaptability coefficient (CA) was used as an indicator of adaptability, according to which PG 16u×966 and PG 3116×ATI hybrids are characterized by high adaptability (CA >100%) for all studied traits.
Keywords: sunflower, hybrid, yield, 1000 seed weight, oil content, adaptability.
