Inheritance of Resistance to Bean Yellow Mosaic Virus in Faba Bean Plants
M.A.S.A. El-Bramawy and E.K.F. El-Beshehy

Bean Yellow Mosaic Virus (BYMV) is one of a devastating pathogen that reduces faba bean crop production in Ismailia. Resistance is limited and resistance-breaking isolates are becoming problematic. Effective BYMV disease control strategies will come from a better understanding of inheritance the resistance to BYMV disease in the crop considering. In this article, we consider the determination role of the inheritance mode of the resistance to BYMV in F1, F2 and F3 faba bean populations. The F1, F2 and F3 progeny of resistant and susceptible faba bean plants were investigated under artificial infection by BYMV in the green house during two successive seasons (2008/09 and 2009/010). Faba bean populatio’s plants were evaluated for the resistance to BYMV using a four-class scale of increasing susceptibility to the BYMV disease which took into account the infected main percentage and disease severity for the faba bean populatio’s plants. Our results analysis confirms that the F1’s was completely resistant and the F2’s was segregated a clear to been 3 resistant: 1 susceptible, while the F3’s families confirmed the F2’s families segregation which suggests as a dominant character controlled by a single locus. This resistance character in faba bean considering has a good potential for direct use in commercial faba bean breeding or for transfer to other faba bean genotypes.
