What is it about?
In Egypt faba bean is considered the most important food legume that provides adequate amount of protein supply in the diet. (Orobanche crenata Forsk.) is a holoparasitic weed that attacks legume crops. It has been a major constraint for legume production in the Mediterranean and East Asia regions since antiquity. little success has been chieved in breeding legumes for broomrape resistance due the scarcity of sources of resistance and the complex inheritance of those available so far. Thus, there is a great need for development of resistant cultivars and for better understanding of inheritance of resistance. The present investigation aimed to 1) studying the faba bean performance and tolerance of genotypes and hybrids to Orobanche and 2) estimating the magnitude of combining ability and type of gene action using diallel analysis.

Why is it important?
our results showed that the studied parents proved to be useful to be utilized in improvement of faba bean. Selection can be conducted in segregating generations of hybrid and their reciprocals crosses distinguished for the development of promising high yield crops and tolerant genotypes.
Perspectives
Breeding strategy of faba bean for Orobanche tolerance necessitates developing faba bean varieties of heterogenous nature to tolerate Orobanche parsitizm. The breeders have to consider this high genetic variation in O. crenata when they breed faba bean for tolerance/resistance to Orobanche. Therefore, breeders have to produce synthetic varieties instead of pure lines.
