Field evaluation of sorghum genotypes against charcoal rot caused by Macrophomina phaseolina (Tassi) Goid.

Abstract

Twenty-seven genotypes were screened for charcoal rot resistance in the sick plot during rabi 2018-19. The results of the study indicated that the genotypes E 36-1 (11.00), followed by SPV 2652 (12.00), SPH 1931, SPV 2468, SPV 2646 and SPV 2647 (13.00) showed minimum charcoal rot index compared to other genotypes. Highest charcoal rot index was recorded in CSH 15R and SPV 2638 (27.00) followed by SPH 1897 (21.00). Out of twenty-seven genotypes screened twenty-five genotypes showed moderately resistant reaction and remaining two genotypes showed susceptible disease reaction.
