An experiment was conducted at College of Agriculture, Nagpur to screen forty different groundnut genotypes against tikka disease of groundnut during kharif, 2016-17 in randomized block design with three replications. Biochemical constituents of phenol, total sugar and chlorophyll at 45-50DAS (flowering stage) and 90DAS (pod development stage) were estimated from leaves of healthy and diseased samples. Forty genotypes of groundnut were screened for tikka disease under field condition. The biochemical changes (total phenol, total sugar and total chlorophyll) in tikka disease were studied in resistant and susceptible genotypes. The high total phenol content was observed in resistant genotypes than in susceptible genotypes and also total sugar content was observed maximum in resistant than susceptible genotypes. The maximum total chlorophyll content was observed in resistant genotypes compared to susceptible genotypes. The phenol and sugar contents increased with the progress of disease with the depletion of chlorophyll content. There was a significant difference in total phenol, total sugar, total chlorophyll contents between the healthy and diseased leaves of resistant and susceptible genotypes. Total phenol and total sugar are the biochemical constituents found more in resistant genotypes and considered as parameter for disease resistance.
