Response of Sorghum Lines and Hybrids from the United States to Long Smut and Grain Mold

Long smut and grain mold are fungal diseases that impact sorghum yield and quality. Long smut infection is most severe in the drier regions of Africa and Asia; whereas, grain mold is the most important disease of sorghum worldwide. In this study, 30 sorghum lines/hybrids were evaluate at the Agronomic Research Stations in Nioro, Senegal, West Africa. Seven lines/hybrids exhibited less than 10% long smut incidence, including AgriPro 2838, and AP 920 that were free of the disease, while NECS 2 had the lowest grain mold severity. The two hybrids AgriPro 2838 and AP 920 may possess genes for long smut resistance and could be utilized in breeding programs for long smut resistance.
