Online published on 24 September, 2020. Abstract A study on resistance against Helicoverpa armigera in tomato genotypes was conducted at the Experimental Farm, Faculty of Agriculture SKUAST-K, Wadura, Sopore during 2016. The correlation coefficients between fruit infestation and fruit/leaf morphological characters revealed that the fruit diameter (r = 0.580, 0.592), number of sepals/calyx (r = 0.974, 0.954) and leaf area (r = 0.670, 0.672) were significant and positively correlated with fruit borer both on number and weight basis, respectively. Trichome density (r =-0.583 and-0.631) and fruit pericarp thickness (r = -0.842, -0.826) exhibited a significant negative association.
