The project was undertaken to study the roleof phenol against MYMV resistance in mungbean plants in natural condition.The present investigation was undertaken during the spring season at Research Farm of Tirhut College of Agriculture, Dholi, Muzaffarpur, Bihar. Four genotypes of mungbean namely HUM-16,TMV-37, Samrat and LGG 450 has been taken. The estimation of total phenol content protocol was carried out with Folin-Ciocalteu Reagent (FCR) by Bray and Thorpe 1954. The absorbance at 650 nm at 1mg/g concentration of phenol was found to be 0.727 a.u. This value was taken as standard as it is very close to the mean value. Highest value of absorbance at 650 nm was found in TMV 37, followed by HUM 16 and Samrat respectively. LGG 450 showed the least value of absorbance which was in direct correlation with MYMV resistance.
