In order to identify sources of genetic resistance to dry root rot caused by Macrophomina phaseolina (Tassi) Goid, twenty-five germplasm accessions of mungbean were screened under field condition during 2006 and 2007. No genotypes appeared free from disease incidence. However, three genotypes namely, ‘MSJ-118’, ‘KM 4–44’ and ‘KM 4–59’ were found to be resistant to dry root rot. These resistant genotypes had significantly greater root and shoot length, root and shoot weight, nodules/ plant and pods/plant than those of the susceptible check, ‘RMG-62’. These lines of mungbean will be used in breeding programmes to develop root rot resistant varieties.
