Nine rootstock cultivars for vine (Vitis vinifera L.) were evaluated: Richter 110 (R110), Paulsen 1103 (Paulsen) and Richter 99 (R99), produced by the hybridization of Vitis berlandieri x Vitis rupestris, SO4 and Telek-Kober 5BB (5BB), produced by the hybridization of Vitis berlandieri x Vitis riparia, MGT 101-14 produced by the hybridization Vitis riparia x Vitis rupestris, Salt Creek and Dog Ridge from the species Vitis champinii, and Quebranta from the species Vitis vinifera; to determine their behaviors against a population density of Meloidogyne incognita. At 5 months after the plants were inoculated, the population variables, reproduction rate (Tr), nodulation -using the Zeck scale and the PIM scale- and plant growth were evaluated. The cultivar Quebranta presented a higher population and Tr, with 37598 nematodes and 0.47 respectively, and the cultivar Dog Ridge presented a lower population and Tr, with values equal to zero, managing to completely annul M. incognita; However, the largest population obtained was smaller than the one initially inoculated; consequently, it was not possible to use the evaluation system proposed by Dropkin and Nelson. In the PIM and Zeck nodulation scales, the cultivars 5BB and Dog Ridge presented lower and higher values respectively, being a lower grade 0.00 for both scales, and a higher grade 3.00 for the PIM scale and 3.33 for the Zeck scale. In growth parameters, the variables that presented significant differences were internode length, number of buds, number of shoots, fresh weight of aerial part and fresh weight of root, with low values in cultivars R110, MGT 101-14, R99 and 5BB, and high values in Quebranta and Dog Ridge cultivars. In dry weight of the aerial part, no significant differences were observed, due to the fact that it registered low values, and the analysis of variance did not detect differences between them.
