Description
Summary:The purpose of this study was to identify common bean genotypes resistant to bacterial wilt to be used as resistancesources in breeding programs targeting resistant cultivars. A total of 67 accessions, five cultivars and one control were evaluated,which were artificially inoculated with the Curtobacterium flaccumfaciens pv. flaccumfaciens isolate Cff 2634. The results prove theexistence of alleles that confer tolerance to bacterial wilt in the cultivars IAC Carioca Aruã, IAC Carioca Pyatã and IAC CariocaTybatã. The mean grades of disease symptoms were lowest in BAF 122 (Xan 159); this accession was identified as disease-tolerantand indicated for use in breeding programs to develop resistant cultivars.
