Pathogenicity and Characterization of Rhizoctonia solani Kühn Inciting Wet Root Rot in Chickpea

Eight isolates of Rhizoctonia solani Kuhn, the incitant of Wet root rot of chickpea were assessed for pathogenicity. Pathogenicity of these isolates varied both in sterilized and unsterilized soils when tested on chickpea variety C-235. All the isolates were pathogenic and isolate Bikaner was highly virulent. The mortality of plant in sterilized soil was higher. There was no correlation between the cultural characters and virulence in any of the isolates.
