Web blight of mungbean is one of the important diseases of mungbean (Vigna radiata L.). Morphological and pathogenic variability of 48 isolates of R. solani from 5 different districts of Uttar Pradesh were studied. Majority of the isolates produced pale brown mycelium with fluffy growth and were categorized into 3 groups on the basis of their growth rate including 11 fast growing, 25 moderately growing and 12 slow growing isolates of R. solani. Sclerotia formed in different isolates were highly variable in number as well as size and it was observed that most of the isolates produced sclerotia of 1-2 mm diameter. Most of the sclerotia were scattered followed by peripheral in Petri plates. The isolates were also variable in respect of their virulence and grouped into three categories such as high (19), moderate (26) and less virulent (3) isolates.
