Biochemical changes were studied in Fusarium wilt resistant and susceptible genotypes during Fusarium udum and Heterodera cajani interaction. Fusarium wilt resistant genotypes, viz. WRP-1 and ICP-8863 recorded increased activities of peroxidase, polyphenol oxidase, phenylalanine lyase and total phenols than Fusarium wilt susceptible genotype, GS-1. A decrease in total sugars was observed in all the three genotypes. Maximum decrease in total sugars was recorded in the Fusarium wilt susceptible genotype, GS-1 followed by ICP-8863 and WRP-1.
