Data from: A genome-wide association study of Nigerien and Senegalese sorghum germplasm of Exserohilum turcicum, the causal agent of leaf blight

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.

高梁为西非塞内加尔的数百万居民提供了日常的卡路里需求。然而，Exserohilum turcicum（叶斑病的病原体）显著降低了作物的产量和经济效益。该数据集基于在塞内加尔西非三个地点复制的地块中种植的共计120个高粱品种（尼日尔和塞内加尔各60个品种）的数据。叶斑病的发病率及严重程度由Louis K Prom、Mame Penda Sarr、Cyril Diatta、Coumba Fall和Clint Magill收集。疾病发病率以感染叶斑病的一行植株数除以该行总植株数，再乘以100计算。严重程度采用0至11的量表，其中中点值分别为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=95.5，11=100，该量表由Prom等人在2023年所描述。该数据集被用于进行全基因组关联研究，以识别与叶斑病发病率相关的单核苷酸多态性。
