ABSTRACT The interaction between Meloidogyne and Fusarium can alter the resistance behavior of passion fruit genotypes. The study was aimed to evaluate the reaction of genotypes of Passiflora spp. to Meloidogyne incognita race 3 (Mi)-Fusarium solani (Fs) complex. The assay was carried using RBD in the factorial arrangement: 10 genotypes (BRS-SC, M-19-UFV, P. alata, P. nitida, P. giberti, P.setacea, P. mucronata, P. murifolia, P. cincinnata, P. ligularis) x 3 treatments (Mi, Mi+Fs, Fs). After 180 days of planting the reaction to Mi was determined by RF (Pi/Pf) and to Fs by lesions size in roots and stems. According to the criteria of Oostenbrink and Moura and Regis, BRS-SC, M-19-UFV. P. alata and P. cincinnata behaved as resistant and P. giberti as susceptible. According to the Taylor and Sasser, BRS-SC, M-19-UFV, P. alata, P. cincinnata and P. giberti behaved as resistant, moderately resistant, moderately suscetible and susceptible, respectively. Lower percentage of plants with symtoms of Fs was found in P. mucronata, P. nitida, P. setacea, P. cincinnata and M-19-UFV In the presence of both pathogens, M-19-UFV, P. alata and P. nitida were those with larger lesion. In the presence de Fs, BRS-SC, P. alata, P. cincinnata and P. ligularis showed the largest lesions.
