Anthracnose of chilli is a serious disease affecting fruit yield and quality of fruit. India is the world leader in chilli production followed by China, Thailand and Pakistan. The experiment was conducted at department of plant pathology, college of agriculture, Bikaner and find out changes in host related enzymes and pathogen related enzymes. The activity of peroxidase, polyphenol oxidase, phenylalanine ammonia lyase and catalase were increased in diseased fruits compared to healthy fruits in resistant variety Pusa Sadabahar, moderate resistant (Mathaniya) and susceptible (Pusa Jawala) varieties. The pathogen related enzymes polygalacturonase trans-eliminase (PGTE), pectin trans-eliminase (PTE), polygalacturonase (PG) and cellulolytic (Cx) enzymes activities were found lower at initial stages of observation.
