Morphological plant factors as basis of resistance against Helicoverpa armigera in different tomato germplasms was conducted at Experimental Farm, Faculty of Agriculture SKUAST-K, during the year, 2016. The correlation analysis between fruit infestation by H. armigera and plant morphological characters revealed that plant height (r = 0.878, 0.844), stem diameter (r = 0.965, 0.943), number ofbranches per plant (r = 0.898, 0.877) and number of fruits per plant (r = 0.874, 0.834) was significant and positively correlated both on number and weight basis, respectively. While the number of flowers per inflorescence (r = -0.811, -0.779) and number of fruits per truss (r = -0.830, -0.812)) had significant and negative association with borer infestation.
