Abstract
A set of 70 diverse genotypes of mungbean were evaluated against powdery mildew in field under natural epiphytotic conditions during rabi 2009–10 and kharif 2010 seasons. During rabi season two genotypes i.e. Pragya and TARM-1 were found to be highly resistant against powdery mildew disease, 8 genotypes were resistant, 12 genotypes were moderately resistant, 20 genotypes were moderately susceptible, 20 genotypes were susceptible and eight genotypes were highly susceptible with Location severity index (LSI) of 3.03. Same set of 70 genotypes screened during kharif 2010 revealed that none of the entries were highly resistant, nine genotypes to be resistant, 15 genotypes were moderately resistant, 16 were moderately susceptible, 22 genotypes were susceptible and eight showed highly susceptible reaction with LSI of 3.07 indicating the role of weather conditions in expression of disease.
