Rubiales, Diego Fernández-Aparicio, Mónica Trabajo presentado en el COST Action FA1206 (WG1, WG2 y WG3 meetings), celebrado en Bucarest del 15 al 18 de septiembre de 2015. Crop resistance aga inst broomrape weeds is a multicomponent phenomenon, being the result of a battery of avoidance factors and (or) resistance mechanisms acting at different levels of the infection process. Preattachment mechanisms of resistance act prior the parasite makes contact with the host root. Among them, low induction of seed germination has been identified in several crop species. Tomato, faba bean and pea accessions that do not induce broomrape seed germination are now available. In pea and tomato, there is a range of strigolactone (SL) deficient mutants that cou ld be explo ited in breeding. In faba bean, a number of well adapted breeding lines have been produced whose resistance is associated with low SL exudation. However, in most instances the mechanisms underlying remains largely unident ified and insufiiciently been exploited in resistance breeding dueto the technical difficulties in its identification. An alternative management strategy to resistance breeding could be exploitation of suicida! germination by synthesizing and directly applying Sl s to the field. In addition, breeding for high SL exudation levels could result in more effective trap cro ps. Another potential application is intercropping. lnhibitory activity of these accompanying inhibitory crops can be increased by se lecting for increased production and exudation of such ale llopathic metabolites. Any of these breeding approaches is possible by simple se lection of existing variation or by various biotechnological approaches. In any case, a closer interaction of breeders with chemists and biochemists is needed. Recent developments in screening and analytical protocols allow a better understanding of the underlying mechanisms. However, they are sti ll time consuming and therefore, unaffordable for breeders that ought to handle massive amounts of segregating populations involving thousands of plants in arder to discard most of them and to retain only the really interesting ones. Therefore, faster although sufficiently reliable throughput screenings methods are still needed.
