A total of 190 recombinant inbred lines (RILs) of mung bean along with parents Kopargaon (susceptible) and ML1720 (resistant) were screened for resistance to Cercospora canescens during three consecutive years (2016, 2017, and 2018) at farm as well as polyhouse. Bartlett’s test for homogeneity of variance revealed heterogeneity in data (at p<0.05). ANOVA revealed significant variation (at p<0.001) among the genotypes for various resistance components. Estimates of Correlation coefficient (at p<0.001) and multiple regression analysis both concluded that Degree of sporulation (SP) and Normalized Difference Vegetation Index (NDVI) are the important parameter for characterizing field resistance against Cercospora Leaf Spot (CLS) of mungbean. Disease severity calculated as AUDPC varied significantly across the year and location. The genotype × environment interactions exerted significant influence (at α = 0.001) which could be reduced by increasing the number of test locations.
