Wheat Yield Trait SNP Associations from a 768-Variety GWAS Panel

544 SNP loci significantly associated with yield-related traits in common wheat, identified through a genome-wide association study. The data is based on a panel of 768 wheat varieties evaluated over two years (2024-2025) in Tai'an, using 49,768 high-quality SNPs. Author Mengyao Li published the dataset on figshare under a CC-BY-4.0 license in 2026.

Use Cases

• Identify candidate genes for wheat yield improvement based on SNP-trait associations.
• Analyze pleiotropic effects of genetic loci based on associations with multiple traits.
• Compare genetic architecture of yield traits between primitive landraces and modern cultivars.
• Select SNP markers for molecular breeding programs based on stable associations detected across years.

Strengths

• Data is derived from a panel of 768 wheat varieties, providing a substantial genetic diversity.
• Association analysis identified 544 significant SNP loci, with 49 consistently detected across two consecutive years.
• Genotyping used 49,768 high-quality SNPs covering 82.73% of the wheat genome.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's 218.8 KB size suggests it is a summary table, not the raw genotype-phenotype data.
