Spinach Bolting GWAS and Genomic Prediction with 16,563 SNPs

A 2026 study by Hanan Alkabkabi provides genomic data on bolting timing in spinach. The dataset includes results from a genome-wide association study (GWAS) of 295 USDA spinach accessions, identifying seven significant loci and candidate genes. It also contains genomic prediction accuracy results for molecular breeding applications.

Use Cases

• Identify candidate genes for bolting time based on the seven significant GWAS loci mentioned in the description.
• Assess genomic prediction accuracy for molecular breeding using the rrBLUP model results.
• Validate SNP markers for breeding programs based on the set of six prioritized GWAS-derived SNPs (m6).

Strengths

• Includes 16,563 high-quality SNPs derived from whole-genome resequencing.
• GWAS analysis identified a major-effect locus on chromosome 6 explaining 21.18% of phenotypic variance.
• Dataset is licensed under CC-BY-4.0, facilitating open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
