SIMAO, Gervásio et al. Behavior of two common bean cultivars in relation to Meloidogyne javanica. Cienc. Rural [online]. 2005, vol.35, n.2, pp.266-270. ISSN 1678-4596.

There is a lack of information on resistance search to the genera Meloidogyne in Phaseolus. The aim of the present research was to evaluate in greenhouse conditions, during summer and winter, the behavior of the common bean cv. Pérola and Iapar 81 against the M. javanica. The reproduction data of M. javanica showed that both cultivars were efficient hosts based upon M. javanica multiplication. Pérola cultivar showed the greatest reproduction index when compared to Iapar 81. Although both cultivars were susceptible at different inoculum concentrations, there was no yield reduction.

Keywords : root knot nematode; Phaseolus vulgaris; susceptibility.
