Behavior of common bean cultivars to common bacterial blight, under greenhouse conditions
Keywords:
Xanthomonas axonopodis pv. phaseoli, Phaseolus vulgaris, Genetic resistanceAbstract
The reaction of common bean cultivars to common bacterial blight (CBC), caused by Xanthomonas
axonopodis pv. phaseoli, was evaluated under greenhouse conditions. Foliar inoculations were made by the
multiple needles method and the disease severity was evaluated at 7, 11, 15 and 19 days after the foliar inoculation
(DAI). The area under the common bacterial blight progress curve (AUCBCPC) was also estimated. At the 19th DAI,
only the cultivars IPR Juriti, BR 6-Barriga Verde and SCS 202-Guará presented greater resistance levels. Cultivars
IPR Juriti, BR 6-Barriga Verde, SCS 202-Guará and Graúna had the lowest AUCBCPC among all cultivars.
