摘　　要：Broomrape causes economic damage in sunflower production in many countries worldwide, but especially in Central and Eastern Europe, Spain, Turkey, Israel, Iran, Kazakhstan, and China. Sunflower selection for broomrape resistance uses different methods for testing breeding materials, looks for resistance sources in certain wild species of the genus Helianthus, and has so far produced significant results. Dominant genes for resistance to races A, B, C, D, E and F have been found and incorporated into cultivated sunflower genotypes. In the last two to three years, new broomrape populations have been discovered in several countries. None of the existing commercial hybrids resistant to races A, B, C, D, E and F have proven resistant to these new populations. Greenhouse testing conducted by the Fundulea Institute in Romania in 2009 has managed to identify two restorer lines that are resistant to all the new populations and can be used directly in developing hybrids. Sunflower breeders and geneticists have achieved significant results in the use of molecular markers for identifying new broomrape races. Marker-assisted selection should be used even more in the future search for Orobanche resistance. Broomrape can also be managed by the development of IMl-resistant hybrids or by using biological control.
