In year 2020, we tested experimental sunflower hybrids at herbicide Pulsar Plus and Express 50SG in three locations, Fundulea1, Fundulea2 and Braila for resistance at biotic factors. Oil content was between 41.24% at H4CL+, treated with herbicide Pulsar Plus and 53.54% at H3CL+, treated with herbicide Pulsar Plus. Seed yield of sunflower hybrids, was between 2258 kg/ha at H4CL+, treated with herbicide Pulsar Plus and 3975 kg/ha at H7E, treated with herbicide Express 50SG. Hectolitre weight (kg/100 l) was between 62.8 kg/hl at H6E, treated with herbicide Express 50SG and 69.1 kg/hl at H5CL+, treated with Pulsar Plus. In location Fundulea 1, sunflower plants infected with pathogen Plasmopara hastedii, was between 0% at sunflower hybrid H3CL+, and 17.5% at sunflower hybrid H4CL+. In location Fundulea 2, sunflower plants infected with pathogen Plasmopara hastedii, was between 4.81% at sunflower hybrid H3CL+, and 73.7% at H5CL+. In Braila location, in year 2020, sunflower plants infested with broomrape, was between 0%, at sunflower hybrid H3CL+ treated with herbicide Pulsar Plus and 100% untreated with herbicide.
