Usefulness of non-senescent parents for charcoal rot resistance breeding in sorghum

摘要

Charcoal rot of sorghum (Sorghum bicolor (L.) Moench) is caused by the fungus Macrophomina phaseolina (Tassi) G. Goid. The disease has a great destructive potential, particularly in postrainy (rabi)-season sorghum. The ability of non-senescent genotypes to remain physiologically active during all growth stages of a crop may contribute to the physiologically active during all growth stages of a crop may contribute to the overall tolerance and isease resistance mechanism, by minimizing the predisposition to charcoal rot infection, and its spread inside the stem (Duncan 1984).
