High-Density SNP Markers for Tropical Maize Inbred Lines

11,203 high-quality SNP markers were retained from an initial set of 31,316 after stringent quality control. The dataset, created by Worknesh Gebre and last updated in May 2026, provides genome-wide coverage for tropical highland maize germplasm. It includes genotype calls and positional information for downstream genetic analyses.

Use Cases

• Assess genetic diversity among tropical maize inbred lines based on the filtered SNP markers.
• Infer population structure within tropical highland maize germplasm using the dense genome-wide coverage.
• Perform linkage disequilibrium (LD) analysis to understand genetic associations.
• Conduct analysis of molecular variance (AMOVA) to partition genetic variation.
• Support genome-wide association studies (GWAS) for trait mapping in maize breeding programs.

Strengths

• 11,203 high-quality SNP markers retained after stringent filtering.
• Filtering criteria are explicitly stated, including MAF ≥ 0.05 and missing data ≤ 30%.
• Dataset provides dense genome-wide coverage for downstream analyses.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or source bias inherent to the specific tropical maize germplasm studied.
