Rezumat

Sunflower resistance to herbicides it was identified in the wild sunflower Helianthus annuus, in 1998 year, in USA. Using the developed cultivated sunflower inbred lines, as sources for resistance, there have been obtained the inbred lines with high agronomic traits, resistant to herbicides. The parasitic plant Orobanche cumana (broomrape) is the most important biotic constraint to the production of sunflower, in all counties were this crop is grown, excepting North and South America. There is a diversity of O. cumana races, identified worldwide. Resistance to the most virulent races of the parasite has been transferred from wild Helianthus into cultivated sunflower, by interspecific hybridization, resulting good sources of resistance. Using backcross or recurrent selection methods we have introduced genes of resistance, in the elite lines. The first hybrids there have been obtained, with possibility to be cultivated in SUNEO technology.
