Abstract Screening of 21 tomato genotypes for their susceptibility to the fruit borer Helicoverpa armigera revealed that all genotypes are susceptible. However, the genotype SK-TVAR 1093 gave maximum fruit yield of 350.46 q/ha with damage of 6.35 and 7.64% on number and weight basis, respectively. The least fruit yield of 267.96 q/ha with damage of 33.52 and 32.64% (on number and weigh basis, respectively) was in the genotype SK-TVAR 1107. Among the commercial cultivars, maximum yield was obtained in Punjab Chuhura (311.19 q/ha) and Arka Vikas gave the least yield (284.47 q/ha). Genotypes SK-TVAR-1048, SK-TVAR-1093, SK-TVAR-1142, SK-TVAR-1181 and H-86 with < 10.0% damage could be categorized as resistant; and the maximum damage of 30.1–40.0% was in the genotypes SK-TVAR-1018, SK-TVAR-1107, SK-TVAR-1121 and Arka Vikas, thus getting categorized as susceptible.
