Theparasitic angiosperm broomrape (Orobanche cumana Wallr.) is currently regarded as one of the most importantconstraints in sunflower (Helianthus annuus L.) production Romania, but especially with highest frequency andintensity of the attack is found in the central and southern part of Moldova, Dobrogea and eastern Plain Baraganu. Inthe last 40 years, efforts to introduce genetic resistance to this parasite in sunflower hybrids were followed by theoccurence of new virulent races that promptly overcame all known resistance genes. Due to this situation, most of theresearch efforts have focused on the development and characterization of new sources of genetic resistance to the mostvirulent races and also, on the genetic variability of Orobanche cumana populations. Different tests for sunflowerresistance to the new races of the parasite, have showed that they are present now in different regions in Romania.Recommendations for reducing sunflower yield caused by broomrape are given.
