Interpretive Summary: Long smut and grain mold are two important fungal diseases of sorghum that can cause significant losses in grain quality and yield. In this study, 30 sorghum lines and hybrids from the United States were screened to identify resistance to these two diseases at the Agronomic Research Station, Nioro, Senegal, West Africa, during the 2011-2012 growing seasons. The work showed that sorghum hybrids AP 920 and AgriPro 2838 were free of long smut infection; while NECS 2 had lowest level of grain mold infection. This work is significant because it has identified two hybrids that can be utilized by breeders in the USA and abroad to develop new long smut resistant sorghum lines and hybrids.

Technical Abstract: 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.
