Reaction of passion fruit genotypes to Meloidogyne incognita race 3 and Meloidogyne javanica

The aim of this study was to evaluate the reaction of genotypes of passion fruit to Meloidogyne spp.. The experiment was carried out in a greenhouse in RBD with six replications in 9 x 2 factorial designs (Passiflora giberti, P. nitida, P. setacea, P. mucronata, P. cincinnata, P. ligularis, P. alata, BRS Sol do Cerrado cultivar and selection M19-UFV x Meloidogyne javanica and M. incognita race 3). According to Oostenbrink criteria, and Moura and Regis, the BRS Sol do Cerrado, and selection M-19-UFV and P. alata behaved as immune to M. incognita. In addition to these, P. cincinnata and P. setacea were immune to M. javanica. Passiflora cincinnata and P. giberti behaved as resistant to M. incognita and M. javanica, respectively. According to Taylor and Sasser, the genotypes classified as immune by the other criteria were classified as resistant to nematodes. All the nematological variables evaluated in P. giberti, P. ligularis, P. mucronata and P. nitida were superior in plants infected by M. incognita. Regardless of the nematode, P mucronata presented larger number of root galls, egg masses, eggs, J2 and RF, as compared to the other genotypes. The root fresh matter weight of P. ligularis and P. mucronata was smaller in the presence of M. incognita as compared to M. javanica.
