DArTSeq Markers for Sorghum and Wide Crosses (sorghum x maize) from East and Southern Africa

This dataset contains DArTSeq marker data generated from 177 sorghum (<i>Sorghum bicolor</i>) accessions collected from diverse sources across East and Southern Africa. The accessions include landraces, breeding lines, commercial varieties, and novel wide crosses (sorghum x maize). Genotyping-by-sequencing was performed using Diversity Arrays Technology (DArT), yielding 30,030 SilicoDArT markers and 15,220 DArTseq SNP markers. The SNP marker dataset, which is provided here, had high call rate, reproducibility, and a mean polymorphic information content. This high-quality marker data enables in-depth analysis of genetic diversity, population structure, and relationships among sorghum germplasm in the region. The dataset can support various applications in sorghum genetics research, including germplasm characterization, association studies, and marker-assisted breeding. By making this data openly available, we aim to facilitate collaborative research and accelerate genetic improvement of this important crop for food security in Africa.
