Behaviour of dry bean cultivars to bacterial wilt

The objective of this research was to evaluate the reaction of 40 dry bean (Phaseolus vulgaris) cultivars inoculated with two isolates of Curtobacterium flaccumfaciens pv. flacummfaciens, and the shoot dry weight of resistant and susceptible dry bean cultivars inoculated or not with this bacteria. The cultivars IAC Carioca Aruã, IAC Carioca Akytã, and IAC Carioca Pyatã were resistant, whereas the following cultivars were susceptible to bacterial wilt: A - 768, Aeté, Aporé, Bambuí, Bico de Ouro, BR IPA 11 - Brígida, Carioca MG, Carioquinha, Catu, Corrente, Diamante Negro, FT Bonito, FT Nobre, FT-120, IAC Carioca, IAC Maravilha, IAC Una, IAPAR 14, IAPAR 16, IAPAR 31, IAPAR 44, IPA 6, Iraí, Jalo Precoce, Jamapa, Onix, Ouro Negro, Pérola, R - 161, RAO 33, Rio Tibagi, Rosinha G2, Roxo 90, Rudá, Safira, Tarumã, and Xamego. Plants of resistant dry bean cultivars (IAC Carioca Aruã, IAC Carioca Akytã, and IAC Carioca Pyatã) had a smaller reduction of shoot dry weight than susceptible cultivars (IAC Carioca and Pérola) when inoculated with C. flaccumfaciens pv. flaccumfaciens.
