Legume crops can be damaged by a number of broomrape species. Orobanche crenata is the most widely distributed in the Mediterranean basin and Middle East. O. foetida and O. aegyptiaca can also be of local importance. Resistance against broomrape in legumes is difficult to access, scarce, of complex nature and of low heritability, and these factors complicate resistance breeding. As a result, only cultivars with moderate levels of resistance are available to farmers. This is further complicated by the fact that several clearly distinct broomrape species can infect the same legume crop, reinforcing the need to search for additional sources of resistance and to test their stability. Available sources of resistance and their undelaying mechanisms and genetic basis on the various legume crops will be reviewed and compared with those available in other crops. Implications in resistance breeding will be critically discussed.
