Application of Classical Methods at Sunflower Breeding Program in Dobroudja Agricultural Institute General-Toshevo

Study was carried out in Dobroudja Agricultural Institute-General Toshevo, Bulgaria. Using classical approaches hundreds inbred lines were developed and collected, distinguished with their valuable agricultural characters and resistance to economic important diseases and parasite Orobanche cumana. Classical sunflower breeding methods applied in DAI-General Toshevo included intraspecific, interlinear, interspecific and intergeneric hybridization, and experimental mutagenesis. Evaluation of resistance to diseases and the parasite broomrape as well as seed oil content were done on confirmed and adapted for the conditions of the institute methods. A lot of sunflower commercial cultivars, own and joint hybrids were created during last 30 years at DAIGeneral Toshevo. Hybrid Maritza, Mura, Veleka, Vokil, Gabi and Velko were widespread in abroad
