The present investigation entitled “Screening of tomato cultivar against fruit borer, Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) infesting tomato†was carried out during rabi season of 2015-16 at Central Experimental Station, Wakawali, Dist.-Ratnagiri. The study revealed that none of the cultivars was found to be free from the infestation of fruit borer. The percent fruit infestation ranged from 15.75 to 42.53 percent. The maximum (42.53%) mean percent fruit infestation was recorded in cultivar Arka Alok, while minimum (15.75%) percent fruit infestation was observed in cultivar BT 105 followed by BT-1 (18.59%). The results revealed that only three cultivars viz., Arka Alok, Thrissur and BL-142 were highly susceptible. The cultivars viz., TH-802, LE-626, LE-1-2, Sonali Sel-1, WKT-2, WKT-3 and WKT-5 were found to be susceptible to fruit borer. The moderately susceptible cultivars were BT-317, BT-105, BT-102-2-2-1, LE-415, SUN-7611, BMZ-21, Sonali, Arka Alok Sel-1, WKT-1, WKT-4, and WKT-6. None of the cultivars found to be resistant to fruit borer, H. armigera infesting tomato. It was revealed that cultivar BT 105 was found to be better cultivar against fruit borer, H. armigera infesting tomato.
