In our paper, we present resistance at drought of eight sunflower hybrids in system Express Sun and in system Clearfield, belonging to NARDI Fundulea, in climatic condition of three years 2020, 2021 and 2022, by analyzing data regarding seed yield, hectoliter weight, seed oil content. Average seed yield in year 2020, was between values of 581 kg/ha at sunflower hybrid FD15CL44 and 2668 kg/ha at sunflower hybrid FD15E27, in year 2021, was between values of 2358 kg/ha at sunflower hybrid FD20CL70 and 4031 kg/ha at sunflower hybrid FD15E27 and in year 2022, was between values of 2814 kg/ha at sunflower hybrid FD22CL83 and 4232 kg/ha at sunflower hybrid FD18E41. Average hectoliter weight in year 2020, was between values of 44.6 kg/hl at sunflower hybrid FD22CL66 and 64.5 kg/hl at sunflower hybrid FD18E41, in year 2021, was between values of 33.6 kg/hl at sunflower hybrid FD20CL70 and 45.6 kg/hl at sunflower hybrid FD19E42 and in year 2022, was between values of 54 kg/hl at sunflower hybrid FD22CL83 and 66.4 kg/hl at sunflower hybrid FD21CL77.
