Reaction of grapevine rootstocks and cultivars to Meloidogyne incognita, M. arenaria and M. hapla

This study aimed to evaluate the reaction of six grapevine rootstocks (MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4, Salt creek) and two cultivars (Quebranta Torontel) three species root-knot nematode (Meloidogyne incognita, M. arenaria M.hapla). The experiment was performed as a completely randomized design with an 8 × 3 factorial scheme replicates per treatment. experimental unit in each replicate comprised cutting planted kg bags sterilized soil. Cuttings were inoculated 5000 eggs + juveniles (J2) hapla. Six months after inoculation, plants removed from bags, determined by evaluating number galls (NG), nematodes gram root (NNGR), reproduction factor (RF). evaluated rootstocks, MGT SO4 Creek, resistant hapla, except for creek, which susceptible latter. Quebranta Torontel Meloidogyne under study.
