Summary: The objective of this study was to prospect sources of resistance to root-knot nematodes in eggplant, scarlet eggplant (gilo), as well in interspecific hybrids between these species and with wild Solanum species, to be used as rootstocks. In the first experiment, in 2013, 10 eggplant accessions, a hybrid between eggplant and gilo, and a Solanum stramonifolium x eggplant hybrid, were evalu41ated for their reaction to Meloidogyne enterolobii. In the second, in 2016, 20 accessions of gilo were evaluated for their reaction to M. incognita, M. javanica, and M. enterolobii.. And in the third experiment, in 2017, one access and two experimental eggplant hybrids, and one Solanum scuticum x eggplant hybrid, were evaluated for their reaction to M. incognita, and M. enterolobii. All the trials were stablished in a greenhouse, and characters related to root infection were evaluated in a completely randomized design with six replications of one plant per pot, using a 1.5 L pots filled with a mixed substrate inoculated with each nematode species. It was found that all eggplant accessions were susceptible to M. incognita and M. enterolobii, however, BER 3150 presented lower susceptibility to M. incognita.
