MOLECULAR VARIABILITY OF DIFFERENT ISOLATES OF Rhizoctonia solani KUHN USING URP-PCR | PLANT CELL..

Rhizoctonia solani causes sheath blight disease, which is a serious rice fungal disease (Oryza sativa L.). Twenty-four isolates of R. solani were genetically characterised using URPs utilising PCR and obtained from various places in Prayagraj (U.P.), India. From R. solani DNA, all primers were determined to be useful for polymorphic fingerprint patterns. One primer (13R) yielded a consistent DNA band in all R. solani isolates out of all the URPs employed. The findings of this study suggest that URPs may be used to measure genetic variability and are very sensitive.
