  Background and Objective: Long smut infection is severe in the drier regions of Africa and Asia, whereas, grain mold is the most important widespread complex disease where sorghum is grown worldwide. Both fungal diseases cause significant losses in grain yield and quality. Long smut has not yet been observed in the United States but there is no guarantee that the disease may never reach the shores. The current study was undertaken to screen selected sorghum lines and hybrids from the U.S. in Bambey, Senegal, West Africa to identify resistance sources. Materials and Methods: In this study, a total of 21 sorghum lines and hybrids from the United States and two Senegalese lines CE 151-262 and CE 196-7-2-1 were evaluated for resistance to long smut and grain mold at the Agronomic Research Station, Bambey, Senegal, West Africa, in 2011-2012 growing seasons. Seeds from sorghum lines and hybrids were planted in a randomized complete block design and replicated thrice. Differences in means among sorghum genotypes were determined at the 5% probability level based on pairwise comparison of least-square means with t-tests. Results: The study showed that sorghum hybrids AP 920 and AgriPro 2838 recorded zero long smut infection, while Triumph 459 was the most susceptible hybrid. All other lines and hybrids had long smut incidence ranging from 2.8-76.3%. None of the lines and hybrids showed resistance to natural grain mold infestation. Conclusion: The two Senegalese lines CE 151-262 and CE 196-7-2-1, exhibited lower grain mold scores than resistant checks SC719-11E and RTx2911. This study also indicated that AP 920 and AgriPro 2838 are resistant to long smut and could be used as resistance hybrids in West Africa.
