Abstract
The status of selection studies on resistant grapevine rootstocks for management of root-knot nematodes Meloidogyne spp. and of Xiphinema index, vector of Grapevine fanleaf virus, is reviewed. The biology, ecology, symptomatology and control of root-knot nematodes are revised, for application in the selection and breeding of resistant rootstocks. Data on resistant Vitis and Muscadinia material, as well as on the genetics, mechanisms and durability of resistance are also provided. The pathogenicity of X. index and of other grapevine nematode vectors is then summarized, as concerns the biology, transmission and classical nematode control. Breeding efforts for selection of grape resistant rootstocks are then reported, focusing on resistance features of M. rotundifolia and V. vinifera × M. rotundifolia F1 hybrids, obtained in California and France, and new prospects are foreseen. Resistance to other nematodes and rootstock applications for control of multiple nematode pests are also discussed.
