Performance of faba bean genotypes with Orobanche foetida Poir. and Orobanche crenata Forsk. infestation in Tunisia

Orobanche foetida Poir. and O. crenata Forsk. are major constraints to faba bean (Vicia faba L.) cultivation in Tunisia. To evalúate the different levels of resistance of seven small-seeded faba bean genotypes to these parasitic weed species, three trials were conducted in fields infested and non-in...
