In this paper we present results about seed yield of some sunflower genotypes in the period 2022-2024, in nine counties from Romania. Three genotypes belonging to NARDI Fundulea were analysed, two experimental sunflower hybrids HS 1112 and HS9233 and one commercial sunflower hybrid FD15E27. In year 2023 was registered the best average seed yield of all three sunflower hybrids of 3189 kg/ha followed by year 2022 with 2930 kg/ha and the lowest average seed yield was registered in year 2024 with 2310kg/ha. Experimental sunflower hybrid HS9233 which is suitable for Clearfield Plus system, registered the highest seed yield of 3045 kg/ha in year 2022 and 3241 kg/ha in year 2023. In year 2024, commercial sunflower hybrid FD15E27 registered the highest seed yield with 2417 kg/ha which is suitable for Express system. The agricultural year 2024 remains representative for the sunflower culture regarding lowest seed yield, because the climate changes were most evident through very high temperatures during the summer.
