Resumo
It was evaluated the occurrence of bacterial wilt in localities of Santa Catarina State, during the harvest of 2002/03 and 2003/04, and the behavior of the genotypes BRS Valente, Carioca, CHC 97-29, CHP 97-26, CNPF 8104, Diamante Negro, Empasc 201 - Chapecó, IAPAR 44, IPR Graúna, IPR Juriti, IPR Uirapuru, LP 9728, Pérola, SCS 202 - Guará, Sel. CP 9310635, TPS Bionobre, TPS Bonito, TPS Magnífico, TPS Nobre, TPS Soberano and Xamego to Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), under greenhouse conditions. The cultivars IAC Carioca Akytã, IAC Carioca Aruã, and IAC Carioca Pyatã were used as patterns of resistance to Cff. The evaluations of the symptoms were performed at 5, 10, 15, 20, and 25 days after inoculation (DAI) and, subsequently, the area under the bacterial wilt progress curve (AUBWPC) was estimated in each genotype. The disease was detected in Campos Novos, Faxinal dos Guedes, Guatambu, Ipuaçu, Ponte Serrada and Tigrinhos. The cultivars SCS 202 – Guará and IPR Juriti showed low wilt severity at 10 DAI. However, at 25 DAI, only the pattern cultivars were resistant and exhibited low AUBWPC.
