THEODORO, Gustavo de Faria; HERBES, Daniel Henrique  and  MARINGONI, Antonio Carlos. Identification of resistance sources of bacterial wilt in common bean landraces, collected in Santa Catarina. Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp. 1333-1339. ISSN 1413-7054.  http://dx.doi.org/10.1590/S1413-70542007000500009.

It was evaluated the reaction of 73 common bean land races, collected in Santa Catarina State, to the bacterial wilt, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens. The experiments were set up under greenhouse conditions and the cultivars IAC Carioca Pyatã and IPR 88 - Uirapuru were the resistant and susceptible standards, respectively. The inoculation with the strain FJ 36 was done in the 10^th day after the sowing and the disease evaluations were at the 10, 14, 21 and 28^th day after the inoculation. The landraces Mouro Piratuba (color bean group) and Vagem Amarela (black bean group) were identified as resistance sources of bacterial wilt of bean.
