The resistant phenotype was found to co-segregate with the SCAR SAP6 marker, located on LG 10. The statistical analysis of all generations followed the model for a dominant resistance gene. Resistant and susceptible F 3:4 sister lines were tested in the field. The F 1, F 2 and F 3 generations were tested under greenhouse conditions. The inheritance of resistance to one of the selected Xap races was determined by analysis of segregation patterns in the F 1, F 2, F 3 and F 4 generations from the cross between the resistant parent PR0313-58 and the susceptible parent ‘Rosada Nativa’. In order to study the inheritance of resistance to common bacterial blight in common bean, a breeding line that showed a differential foliar reaction to Xap strains was selected and was crossed with a susceptible parent. A few common bean lines show a differential reaction when inoculated with different Xap strains, indicating the presence of pathogenic races. Variability in virulence of the bacterial pathogen has been observed in strains isolated from Puerto Rico and Central America.
