Among bacterial diseases that affect dry beans, common bacterial blight, caused by Xanthomonas axonopodis pv. phaseoli, can considerably reduce grain yield of this crop and is the most important in Brazil. Genetic resistance is one important characteristic to be considered in the integrated disease management during the development of new dry bean cultivars. The objective of the present research was to obtain dry bean lines resistant to common bacterial blight using the single seed descent method. Thirty lines resistant to common bacterial blight were obtained with considerable reduction in generation advance time.
