Anastomosis and cross-infection potential of Rhizoctonia solani: a comparative study of rice and potato isolates

Potato is planted after rice in different parts of India, especially in Haryana, as a part of the rice-potato sequential cropping system, and both crops are infected by Rhizoctonia solani Kuhn. Potato tubers exhibiting black scurf and rice plants affected by sheath blight were collected from various regions of India, and isolates of R. solani were obtained. Cross-infection potential of R. solani was assessed by inoculating rice isolates onto four potato cultivars and potato isolates onto four ri
