Abstract: The field experiment was conducted with thirty green brinjal varieties to identify biochemical characteristics of brinjal plants for their resistance against shoot and fruit borer infestation. Various biochemical parameters like total phenol, polyphenol oxidase, total sugars and solasodine were recorded from different genotypes used. Among the genotypes, ABSR-2 recorded the low total sugar content, high total phenols and polyphenol oxidase activity was resistant to the infestation of Leucinodes orbonalis. Whereas, the susceptible genotype IC 249344 showed the lowest polyphenol oxidase and solasodine content. Out of thirty green genotypes, ABSR-2 exhibited highly resistant to shoot and fruit borer. Hence, the breeders can utilize the above genotype for develop a new variety/hybrid with desirable resistance, high yield and quality through hybridization and selection. The association analysis carried out in this study revealed that fruit infestation percentage was significantly negative correlation with polyphenol oxidase (-0.68), solasodine (-0.43) and total phenol (-0.49) and positive correlation with total sugars (0.74). The present investigation provided precise information for the selection of important biochemical characters which may contribute more towards resistance to shoot and fruit borer.
