Resistance against broomrapes (Orobanche and Phelipanche spp.) in faba bean (Vicia faba) based in low induction of broomrape seed germination
Euphytica 186 (3), 897-905
Abstract: Broomrapes are weedy root parasitic plants that severely constraint faba bean production. After long and extensive breeding efforts made in several countries only moderately resistant cultivars are available to farmers, being their resistance based on a combination of avoidance and resistance mechanisms. In this work we characterize the resistance mechanism of two faba bean breeding lines selected for resistance to Orobanche crenata. Mini-rhizotron experiments showed that low induction of seed germination is a major component of resistance in these lines against O. crenata, O. foetida and P. aegyptiaca. This is confirmed by in vitro experiments with root exudates. The fact that low induction of germination is similarly operative against O. crenata, O. foetida and P. aegyptiaca reinforce the value of this resistance.
