Abstract:
Field experiment was conducted at Farm, college of horticulture, Mandsaur during summer season of 2020-21 and 2021-22, to determine the varietal resistance of cucumber (Cucumis sativus L.) against the infestation of fruit fly Bactrocera cucurbitae in randomized block design with three replications and one meter plant spacing. Ten cucumber hybrids viz., Hybrid Cucumber EZ15-W-08, Cucumber Super Green, SAIRA-934, Cucumber Green Long(S-82), Saloni, Punheri, Cucumber Green Gold-7 (standard check), Jannat, Gen-2215 and Cucumber Gautam-910 were screened against fruit fly. Observations on fruit fly infestation were recorded from 15^th to 20^th SMW weekly in fruiting stage of crop during both the years on the basis of total number of fruits and damaged fruits. Based on two years pooled mean, variety SAIRA-934 (10.50%) was considered highly resistant, Saloni (14.60%)> Cucumber Green Long(S-82) (13.98%)> Cucumber Green Gold-7 (12.62%) were resistant and Cucumber Super Green (29.52%)> Punheri (28.56%)> Cucumber Gautam-910 (28.46%)> Hybrid Cucumber EZ15-W-08 (27.65%)> Jannat (26.86%)> Gen-2215 (25.27%)were categorized as moderately resistant varieties.
