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