Variation in virulence of Macrophomina phaseolina isolates causing dry root rot of chickpea and performance of chickpea genotypes against this disease

Abstract

Twenty isolates of Macrophomina phaseolina were collected from ten major chickpea growing states of India. Virulence of the isolates were tested on susceptible chickpea cultivars viz., H 09-23, L-550 and BG-212. A total of 215 chickpea genotypes were screened in sick plot, none of them were found resistant. However, only two entries viz., RSG 888 (2) and ICCV 93706 showed moderately resistant reaction.
