Changes in chlorophyll, sugar and phenolic compounds in resistant and susceptible genotypes of greengram were studied. The chlorophyll and sugar content were found to decrease due to the infection of Colletotrichum truncatum and the rate of decrease was more in susceptible genotypes (Chinamung, Yellowmung and S-4) than resistant genotypes (TM-96-2 and TARM-18). However, phenol content was found increased due to infection and the rate of increase was higher in resistant genotypes. Comparatively lesser sugar and higher phenol content were observed in resistant and moderately resistant genotypes than in susceptible genotypes.

The chlorophyll and sugar content were found to decrease due to the infection of Colletotrichum truncatum and the rate of decrease was more in susceptible genotypes (Chinamung, Yellowmung and S-4) than resistant genotypes (TM-96-2 and TARM-18). However, phenol content was found increased due to infection and the rate of increase was higher in resistant genotypes. Comparatively lesser sugar and higher phenol content were observed in resistant and moderately resistant genotypes than in susceptible genotypes.
