Abstract:

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 (4.8) followed by Sahebi (4.6), Hussaini (4.5) and Thompson seedless (4.0) and they were categorized susceptible to M. hapla. Tas-e-Ganesh and Manjri Naveen each with gall index 3.8 were moderately susceptible whereas, Fantasy 4 seedless was with least gall index (2.3) followed by K.R. White (2.5) and Kishmishi (2.6) and categorized as moderately resistant cultivars. Egg mass per root system was recorded maximum on Pusa Navroz (92.0) followed by Sahebi (87.66). Minimum egg masses were found on Fantasy 4 seedless (7.16) closely followed by K.R. White (8.66) and Kishmishi (8.83). Eggs per egg mass were found maximum in case of susceptible (223-290), followed by moderately susceptible (125-215) and moderately resistant cultivars (34-37). All the grapevine cultivars supported the multiplication of nematodes evidenced by a significant increase in the soil population of M. hapla (P≤ 0.05). The cultivars supporting nematode multiplication in decreasing order was Pusa Navroz > Sahebi > Hussaini > Thompson seedless > Tas-e-Ganesh > Manjri Naveen > Red Globe > Fantasy 4 seedless > K.R. White > Kishmishi. A significant decrease (P ≤ 0.05) in fresh and dry shoot weight as well as fresh and dry root weight was observed, however they varied with respect to susceptible, moderately susceptible and moderately resistant cultivars. Maximum reduction in fresh and shoot weight was recorded in Pusa Navroz (31.94 and 41.26%, respectively) and minimum in Fantasy 4 seedless (10.43 and 14.06%, respectively). Maximum reduction in fresh and dry root weight was recorded in Pusa Navroz (50.15 and 53.54%, respectively) and minimum in Fantasy 4 seedless (25.94 and 25.90%, respectively).
