This study presents the evaluation of hybrid forms, obtained as a result of interspecific hybridization between four sunflower inbred lines and wild annual H. debilis and H. petiolaris accessions from the collection of wild Helianthus species at Dobrudzha Agricultural Institute, on various indices related to their seed oil and protein content. The selected accessions, used as paternal parents in the crosses and the obtained hybrid material, were previously tested and evaluated as resistant to leaves pathogens. The indices 1000 seed weight (g), kernel and hull (%), oil content in kernel (%) and in seed (%), and seed protein content were evaluated. The results showed very good statistical authenticity of the analytical hypothesis that the investigated hybrid forms were with different genetic potential on the studied indices, pointing to the existence of high variability among the used wild germplasm. Hybrid forms, resistant to leaves pathogens, with high oil and protein content were obtained
