Studies on Biochemical Changes in Fusarium Wilt Resistant and Susceptible Genotypes during Fusarium udum and Heterodera cajani interaction in Pigeonpea

摘要

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.
