Morphological, cultural and sclerotial variability among isolates of rhizoctonia solani causal agent of web blight of soybean

In the present study morphological, cultural and sclerotial variability was observed among 17 isolates collected from five districts of Chhattisgarh. Lowest hyphal width was observed to be that of RS 10(2.16 μm) and highest hyphal width was observed to be that of RS 14(4.38 μm) the least angle of branching was observed to be that of RS 12(77.45˚) and the highest angle of branching was observed to be that of RS 5(95.743˚). Significant variation in distance between septa was also observed among the isolates (36.34 to 11.33 μm). | Morphological, cultural and sclerotial variability among isolates of rhizoctonia solani causal agent of web blight of soybean
