Expression of Tolerance to Pod Borer, Helicoverpa armigera (Lepidoptera: Noctuidae) in Relation to Biochemical Content of Chickpea Leaves uri icon

abstract

  • The pod borer (Helicoverpa armigera) is one of the most serious pest of chickpea and plantresistance is an important component for managing this pest. To develop cultivars withresistance to insects, it is important to understand the role of different componentsassociated with resistance to insects. Therefore, in this study we characterized RIL?s(recombinant inbred lines) population for total phenol content leaves and organic acidprofiles in the leaf exudates which are associated with tolerance to H. armigera. Chickpealeaves 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 liquidchromatography (HPLC) profiles of the leaf exudates of 196 RIL?s exhibited amounts of allorganic acids were negatively correlated with egg count, larval incidence and with poddamage. Total phenol levels were negatively associated with egg count, larval incidenceand pod damage percentage
