Screening of different genotypes of tomato against major pests infesting tomato (Solanum lycopersicum L.)

The present investigation entitled “Screening of different genotypes of tomato against major pests infesting tomato (Solanum lycopericum L.)” was carried during rabi season of 2018-2019 at Central Experimental Station, Wakawali. Fifteen genotypes were screened against whiteflies, aphids, leaf miner and fruit borer under field condition. The genotypes showed different responses for different pests. The highest mean population of whiteflies was recorded on the genotype Konkan Vijay (4.74), while lowest was observed on N-2257 (3.34) per three leaves. In aphids, the most promising genotype was N-2257 (2.10) mean population per three leaves, while genotype SUN-7610 was most infested by aphid (3.05) per three leaves. Highest leaf miner infestation was recorded on genotype LE-66 (34.32%) and lowest was noticed on genotype BT-1 (30.24%). The maximum fruit borer infestation recorded in genotype N-2257 which were found 44.71 and 41.28 per cent on number and weight basis, respectively. The lowest 19.78 mean per cent fruit infestation on number basis was recorded in genotype BT-105, whereas 18.74 per cent on weight basis was found in same genotype. N-2257 was the best genotype with least attack of whitefly and aphids while, BT-1 was proved as the best against leaf miner infestation and BT-105 against fruit borer infestation.
