Common bacterial blight (CBB) is an endemic disease of common bean (Phaseolus vulgaris) caused by Xanthomonas phaseoli pv. phaseoli
(Xpp) and Xanthomonas citri pv. fuscans (Xcf).
• A complete resistance to CBB is lacking and the efficacy of known resistance varies depending on the strain tested.
• Methods for disease assessment and resistance scoring differ by their efficacy in differentiating the virulence of strains and the resistant
genotypes .
• Effective disease phenotyping methods are essential for searching novel resistant genotypes.
• AIM: To select among 4 different inoculation methods the most effective for virulence discrimination, resistant genotype selection, time
efficiency and assessment method
