    Abstract

    The pod borer (Helicoverpa armigera) is one of the most serious pest of chickpea and plant resistance is an important component for managing this pest. To develop cultivars with resistance to insects, it is important to understand the role of different components associated with resistance to insects. Therefore, in this study we characterized RIL’s (recombinant inbred lines) population for total phenol content leaves and organic acid profiles in the leaf exudates which are associated with tolerance to H. armigera. Chickpea leaves contained phenol and five major organic acids, which were identified as malic acid, oxalic acid, acetic acid, citric acid, and fumaric acid. The high performance liquid chromatography (HPLC) profiles of the leaf exudates of 196 RIL’s exhibited amounts of all organic acids were negatively correlated with egg count, larval incidence and with pod damage. Total phenol levels were negatively associated with egg count, larval incidence and pod damage percentage.
