Axiom®Vitis22K SNP Array: Grapevine Genotyping Data for 144 Genotypes

10,314 robust polymorphic markers and 13 curated variants from a 22K SNP array designed for grapevine genetics. The data was generated by genotyping 144 genotypes from two diversity panels to validate the array. Laura Costantini published this dataset on figshare under a CC-BY-4.0 license, with a last update in March 2026.

Use Cases

• Assessing genetic diversity and population structure based on genome-wide SNP markers.
• Validating candidate SNPs associated with traits like flower sex type, seed content, berry color, and taste.
• Implementing marker-assisted selection in grapevine breeding programs using the identified polymorphic markers.
• Studying genetic relationships between cultivated Vitis vinifera and wild Vitis species from the described diversity panels.

Strengths

• Contains 10,314 robust polymorphic markers validated across 144 genotypes.
• Integrates SNPs from multiple sources, including a prior 18K chip, literature-derived trait associations, and novel resequencing data from 12 samples across seven species.
• Data is published under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is relatively small at 9.1 MB, which may limit the scope of some analyses.
