Charcoal rot of sorghum

Twenty-three 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 (12.00) followed by SPH 1903, SPV 2654, SPV 2655, SPV 2656 and CSH 13R (13.00) showed minimum charcoal rot index compared to other genotypes. Highest charcoal rot index was recorded in SPV 2662 (31.00) followed by Phule Anuradha (29.00). Out of twentythree genotypes screened twenty-one genotypes showed moderately resistant reaction and remaining two genotypes showed susceptible disease reaction.

Genetic variability, heritability, genetic advance and correlation were estimated for charcoal rot component traits, yield and its component traits. High values of PCV and GCV were observed for majority of traits, indicating a greater scope for improvement of these traits. High heritability coupled with high genetic advance over mean was observed for majority of traits, indicating these characters would be more effective for further improvement through simple selection.

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).

Charcoal rot of sorghum caused by Macrophomina phaseolina is a disease of economic importance for which a high level of genetic resistance is not available. Therefore, an effort was made to manage this disease with potent rhizobacterial strains viz., AUDP 139 and AUDT 801 in CSV 8R and CSV 29R cultivars. In CSV 8R, seed soaked in supernatants of AUDP 139 for two hours recorded least charcoal rot incidence of 40.58 % with highest yield of 1924.90 Kg/ha whereas in CSV 29R, seed treatment with AUDT 801 + AUDP 139 @ 3g/Kg of seeds recorded least disease incidence of 14.
