The resistance to broomrape in 15 new experimental hybrids was tested on locations in Serbia (Pacir) during three years (2006, 2007, and 2008) and in Romania (Baragan, Braila) during 2008. These hybrids were produced by crossing female inbred lines (Ha-26PR-A, PH-BC2-92-A and Ha-98-A) susceptible to broomrape race E and new Rf inbred lines (RHA-D-2, RHA-D-5, RHA-D-6, RHA-D-7, RHA-D-8), developed from interspecific populations originating from H. deserticola and resistant to race E. All examined hybrids were resistant to broomrape in both locations. Since broomrape race F is present in the location in Romania, it is expected that the new Rf inbred lines - male components of the examined hybrids, possess the resistance gene for race F also.
