Stem rot disease (causal organism- Sclerotium rolfsii Sacc) is important disease of groundnut causing severe loss in production. Morphological and cultural characters of Sclerotium rolfsii was studied on PDA solid media in the present study. Twenty five isolates of Sclerotium rolfsii collected from different locations of North-Bengal districts of West Bengal from rice-based cropping system, infecting groundnut in cross inoculation, were studied on potato dextrose agar(PDA) for their cultural and morphological variability. Significant variability with reference to mycelial and sclerotial characters across isolates of Sclerotium rolfsii, isolated from different locations was observed. It was found that the growth rate was varied from 0.772mm/hr to 1.12 mm/hr. and size of the sclerotia was found to be in the range between 2.9mm to 7.5mm. Colony colour varied from buff white to pure white, with smooth to coarse texture and regular to irregular margin. Production of sclerotial bodies started from 5th day onwards. Sclerotial shapes were ellipsoidal to spherical with light brown to dark brown colour.
