RODRIGUEZ MIRANDA, Odile et al. Answer to common bacterial blight (Xanthomonas axonopodis p.v phaseoli) in the commercial cultivars of common bean of Cuba, under field conditions. Affectation of the yields for effect of the inoculation. cultrop [online]. 2015, vol.36, n.2, pp. 92-99. ISSN 1819-4087.

It is possible to find in a Cuban bean germplasm, cultivars whith some level of resistance to a pathogenic strain of Xanthomonas axonopodis pv. Phaseoli which allow to diminish the losses and increase the yield average of the crop on infected fields. The goals of this work were to evaluate differentials responses of common bean genotypes to natural infection and inoculation with the pathogenic strain of Xap 527 and identify commercial cultivars with better behavior to damages on leaves and sheaths and there fore less losses on yield. The results allowed selecting bean genotypes, with good behavior against the studied strain Xap. The decreases of the yield were determined in the studied bean cultivars by its reaction of susceptibility in front of common Bacteriosis, with the inoculation of Cuban the 527Xap strain
