Abstract
The susceptibility of nine grape cultivars (Bez Alanza, Early Sweet, Flame Seedless, Mangawy, Queen, Red Globe, Romy Red, Sperior and Thompson Seedless) were tested for the two nematode species (root-knot nematode, Meloidogyne incognita and reniform nematode Rotylenchulus reniformis) under greenhouse conditions. The results indicated that both nematode species reproduced well on all tested grape cultivars, also grape cultivars were different in their susceptibility to both nematode species. The cultivars were ranked for their susceptibility against M. incognita as follows: two cultivars, Mangawy and Queen were categorized as very resistant to the nematode. Red Globe and Thompson Seedless cultivars were considered as slightly resistant. On the other hand, five cultivars Bez Alanza, Early Sweet, Flame Seedless, Romy Red and Sperior were graded as susceptible. As for the response of these grape cultivars to the R. reniformis Bez Alanza, Mangawy, Queen and Romy Red were categorized as highly resistant. Only Sperior was rated as resistant. Early Sweet, Red Globe and Thompson Seedless were considered as less susceptible. In contrast, one cultivar Flame Seedless was ranged as highly susceptible. Plant growth parameters of tested grape cultivars were also discussed.
