Dry root rot caused by Rhizoctonia bataticola (Taub.) Butler [Pycnidial stage: Macrophomina phaseolina (Tassi) Goid] is a soil borne fungal pathogen. Keeping in view the importance of the disease due to change in climatic conditions, studies were conducted on distribution of the disease, cultural, morphological, pathological and molecular diversity. The experiment was conducted at Department of Plant Pathology CSA, Kanpur. In the present studies, twelve isolates of R. bataticola were isolated form disease sample of dry root rot of chickpea collected from different farmer’s fields from twelve villages in Derapurtahsil in Kanpur, Uttar Pradesh, India. The pathogen was isolated and purified in PDA media by using standard isolation procedure and its pathogenicity was proven in pot culture. Further, on the basis of cultural characteristics and morphological characteristics of the pathogen, the fungal pathogen was identified as R. bataticola. In cultural characteristics six characters like colony colour, colony diameter, pigmentation, margin type, growth pattern and aerial hyphae were recorded. Maximum radial growth i.e. 90 mm was given by isolate Rb-07 of Sabalpur village followed by Rb-02 and Rb-12. Least radial growth of 45 mm was given by Rb-03 isolate of Nandpur village. Pigmentation was also observed in four isolates. Aerial hyphae were produced by six isolates.
