Morphological variability inRhizoctonia solaniisolates from different agro-ecological zones of West Bengal, India

Sheath blight caused by Rhizoctonia solani Kühn is one of the most important diseases of rice, resulting in significant yield loss in rice every year. The rice-based intensified cropping system, edapho-climatological and host variations make the disease problem more complicated. However, the incidence and severity of the disease differ from one location to other, one geographical area to other and even differs from country and region wise. The reasons for this disease severity have been attributed to the variation in host genotype, virulence of the pathogen, prevalence of congenial soil physico-chemical and plants' surrounding environment and cultural practices. Sixty-seven number of isolates of R. solani from rice, 12 no. of R. solani isolates associated with maize, sugarcane, weeds, cabbage, pointed gourd, watermelon, potato, dolichos bean and aparajita were isolated from different agro-ecological region of West Bengal and three no. of isolates of R. oryzae-sativae obtained from Department of Plant Pathology, BCKV, were used in the present study. Cultural and morphological characteristics revealed considerable diversity among the R. solani isolates. Cultural and morphological analysis of WB isolates of rice has indicated that the diversity among the isolates does not correlated with their origin. On the basis of morphological characteristics, R. solani isolates could be easily separated from R. oryzae-sativae isolates. The no. of sclerotia, hyphal length, wt. of sclerotia and mycelial growth rate are the important morphological markers for differentiation of R. oryzae-sativae from R. solani isolates.
