TAILIEUCHUNG - Resistance of grapevine cultivars to meloidogyne hapla under polyhouse condition

A study was carried out to evaluate ten grapevine cultivars against root-knot nematode Meloidogyne hapla under polyhouse condition. The cultivars showed varying degree of susceptibility against nematodes in relation to nematode infestation and plant growth parameters. None of the grapevine cultivars used in the study was found to be highly resistant or resistant against M. hapla. Gall index was maximum in cultivar Pusa Navroz () followed by Sahebi (), Hussaini () and Thompson seedless () and they were categorized susceptible to M. hapla. Tas-e-Ganesh and Manjri Naveen each with gall index were moderately susceptible whereas, Fantasy 4 seedless was with least gall index () followed by . White () and Kishmishi () and categorized as moderately resistant cultivars. | Resistance of grapevine cultivars to meloidogyne hapla under polyhouse condition
