Abstract

Seventy-eight 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 (11.53 %), followed by DSV 4 (12.24 %), Dagadi Solapur (13.40 %) showed less disease incidence compared to other genotypes. Highest per cent charcoal rot incidence was recorded in CSV 8R (54.34 %). The study also revealed that the local genotypes recorded reduced levels of other charcoal rot parameters such as per cent lodging due to charcoal rot (soft stalk), mean length of spread (MLS) and mean number of nodes crossed (MNC). The local genotypes also possessed desired breeding traits such as delayed senescence and stay green type which could be employed in resistance breeding programme of rabi sorghum.
