Immature sunflower ( Helianthus annuus L.) zygotic embryos of sunflower fertility restorer line R 2574 were treated with ultrasound before planting on the embryo culture medium. As a result some chlorophyll leaf and inflorescence mutations were observed. New sunflower forms with inherited morphological biochemical and phytopatological changes were obtained through selection and self-pollination. The line R 12003 subjected to investigation in this study was characterized with significant changes concerning most of the studied characters. The contribution of the present research connected to the investigated mutation was the appearance of resistance to the parasite broomrape. The increased number of seeds per head in line R 12003 increased oil content in seed and 100% resistance to the parasite Orobanche are the desired combination in the breeding programme of sunflower.
