The diseases caused by bacteria present a phytopathological and agricultural problem in various economic crops. The Curtobacterium wilt caused by Curtobacterium fl accumfaciens pv. fl accumfaciens has become a threat to the cultivation of beans (Phaseolus vulgaris L.). The disease statement for the Brazilian territory occurred in 1995 and today the pathogen is distributed in various Brazilian producing regions. Transmission is primarily via contaminated seed, which imposes great diffi culties and limitations on the control of these bacteria. After plant infection, the only way to control it is the eradication of infected plants. The alternatives for the control of this disease are the use of healthy seeds, crop rotation and resistant varieties. The use of resistant varieties is the most effi cient and economical solution for the farmer. The most important research to support the development of bean cultivars resistant to C. fl accumfaciens pv. fl accumfaciens is the identifi cation of sources of genetic resistance and the study of mechanisms of genetic resistance to disease.
