Legume cultivation is hampered in Mediterranean regions by the occurrence of of the parasitic weed Orobanche crenata (broomrape). Breeding for resistance is possible, but is hampered by the lack of sufficient levels of resistance, the complexity of its inheritance and the unreliability of available screening methods. Still, progress have been made in pea and faba bean accumulating the available quantitative resistance by breeding, allowing the release of resistant cultivars. Some resistance have also been identified in lentil, grasspea,commonvetch and chickpea, as well as in their wild relatives. QTLs for resistance have been identified in faba bean and pea but were are still far for being able of using them effectively in MAS. Not only further saturation of the maps is needed, but also a more refined phenotyping and integration of information obtained from QTL analysis with gene and protein expression analysis. Also, sequence information obtained from other parasitic weeds will help in understanding parasite virulence and host resistance mechanisms.
