RESUMO
The objective of this work was to assess the reaction of field and snap bean cultivars to the infestation by Meloidogyne incognita races 1 and 3 and Meloidogyne javanica. Three independent experiments to each species and race of Meloidogyne with four replicates and four plants per plot were conducted. In each block, a plot with the susceptible tomato cultivar Santa Clara was employed to verify the efficiency of the inoculum and calculate reproduction rate. The bean cultivars Aporà and Talismà were greatly resistant in relation to Meloidogyne javanica, slightly resistant to Meloidogyne incognita race 1 and moderately resistant and slightly resistant, respectively, to Meloidogyne incognita race 3. The snap bean cultivars MacarrÃo Atibaia and MacarrÃo Preferido proved slightly resistant to Meloidogyne javanica, moderately resistant and susceptible, respectively, to Meloidogyne incognita race 1. But for Meloidogyne incognita race 3, they presented themselves as very resistant and slightly resistant, respectively. The results of these experiments showed that the bean cultivar Aporà and snap bean cultivar MacarrÃo Atibaia presente a potential to the use in programs of improvement for root-knot nematodes resistance evaluated, being this snap bean cultivar also recommended for planting in areas clearly infested by these root-knot nematodes.
