Sorghum supplies the daily calorie needs of millions of inhabitants in Senegal, West Africa. However, Exserohilum turcicum, causal agent of leaf blight significantly reduces the crop's productivity and profitability. Data based on a total of 120 sorghum lines (60 lines each from Niger and Senegal) planted in replicated plots in three locations in Senegal, West Africa. The leaf blight incidence and severity were collected by Louis K Prom, Mame Penda Sarr, Cyril Diatta, Coumba Fall, and Clint Magill. Disease incidence was based on the number of plants infected with leaf blight in a row divided by the total number of plants in the same row multiplied by 100. The severity scale 0 to 11 with mid-points, where 1=5.5, 2=15.5, 3=25.5, 4=35.5, 5=45.5, 6=55.5, 7=65.5, 8=75.5, 9=85.5, 10=95.5, and 11=100 previously described by Prom et al. 2023 was used. the dataset was used to perform genome-wide association studies to identify single-nucleotide polymorphisms associated with leaf blight incidence.
