Sp75: 10,074 SNPs Across 243 Spinach Lines for Downy Mildew Resistance

A genome-wide association study (GWAS) dataset for downy mildew resistance in spinach. It contains 10,074 single nucleotide polymorphisms (SNPs) genotyped across 243 spinach lines. The dataset was authored by Ainong Shi and last updated on April 19, 2026.

Use Cases

• Identify genetic markers for downy mildew resistance based on SNP data.
• Perform association mapping to link genomic regions with disease resistance traits.
• Conduct population genetics analysis on the 243 spinach lines.
• Validate or compare SNP-based breeding strategies for crop improvement.

Strengths

• Contains 10,074 SNPs, providing a dense marker set for analysis.
• Genotyped across 243 lines, offering a substantial sample for population-level studies.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse.

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 bias inherent to the specific spinach lines and genotyping platform used.
