Abstract:

Wilt complex is one of the important diseases of betelvine causing severe losses in betel leaf production. In the present study Cultural characters of Sclerotium rolfsii was studied on six different solid media. Among the solid media tested, maximum radial growth was observed on potato dextrose agar and oat meal agar. Ten isolates of S. rolfsii collected from different locations of northern Karnataka were studied on potato dextrose agar for their cultural and morphological variability. Colony diameter ranged from 75.33 to 90.00 mm. 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 4th day. Sclerotial bodies are ellipsoidal to spherical in shape with light brown to dark brown colour.
