This study evaluated, under controlled conditions, the reaction of ten grape rootstocks from a germplasm collection at the Programa de Melhoramento Genético de Videira, Centro APTA de Frutas do Instituto Agronômico de Campinas, Brazil, against Meloidogyne incognita and M. javanica nematodes. Seedlings were inoculated with 4,000 eggs and juveniles. After 60 days, root systems were evaluated with respect to the amount of galls in order to determine, by calculating reproduction rates, immunity, resistance and susceptibility. Rootstocks 101-14, Teleki-5C, IAC 313, IAC 766, Kober 5BB and Ripária do Traviú behaved as immune to both species of nematodes - R99 was resistant. IAC 571-6 and IAC 572 behaved as resistant to M. incognita and immune to M. javanica; 420-A was immune to M. incognita and resistant to M. javanica.
