AGG Barley: Genotypes for 27,242 Barley Genetic Resources

27,242 barley Plant Genetic Resources from the Australian Grains Genebank were genotyped using the Illumina Infinium Wheat Barley 40K v1.1 BeadChip. The dataset, authored by the Australian Grains Genebank, provides genotype data in multiple formats including raw and imputed VCF files. It was last updated on May 1, 2026.

Use Cases

• Conducting genome-wide association studies (GWAS) based on the 40K marker panel.
• Performing population structure analysis based on the genotype data for 27,242 accessions.
• Imputing missing genotype calls for downstream analysis based on the provided filled-in VCF files.
• Anchoring genetic markers to a reference genome for comparative genomics based on the genome-anchored VCF files.

Strengths

• Contains genotype data for 27,242 barley accessions, providing a substantial sample size.
• Funded by a $30M strategic partnership, indicating a significant resource investment.
• Data is provided in multiple processed formats (e.g., raw, unique, imputed) for different analytical needs.

Limitations

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