SNPLDB: High-Resolution Haplotype Map for Cultivated Peanut

A high-resolution haplotype map for cultivated peanut (Arachis hypogaea L.) serves as a foundational resource for genetic studies and breeding. The dataset was constructed from 353 globally representative core accessions and overcomes the limitations of bi-allelic SNP markers by capturing multi-allelic variation. It was authored by Xiurong Zhang and last updated on 2026-05-25.

Use Cases

• Identifying genetic markers for trait selection based on multi-allelic variation.
• Conducting population genetics studies based on a globally representative set of 353 accessions.
• Supporting genomic selection and breeding programs for cultivated peanut.
• Analyzing haplotype diversity and structure within the peanut genome.

Strengths

• Captures multi-allelic variation, overcoming a limitation of standard bi-allelic SNP markers.
• Built from 353 globally representative core accessions, providing a broad genetic sample.
• Released under a permissive CC-BY-4.0 license for wide reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• The 92.1 MB size suggests a relatively small dataset for modern genomics.
