Abstract: Root rot caused by Macrophomina phaseolina is the serious disease in sesame. The incidence of Macrophomina rot leads to great problems at such magnitude so that the area under sesame cultivation is declined gradually. Twenty four advanced breeding lines were screened for Macrophomonia root rot under sick plot conditions. The disease severity of root rot ranged from 17.4% to 41.6%. Advanced breeding lines viz., VS 16 004 and VS 16 008 recorded less disease incidence of 17.4% and 17.6% respectively, whereas the susceptible check VRI Sv 1 recorded the maximum disease incidence of 41.6%. However most of the lines were found to be moderately susceptible to root rot.
