Garlic DNA Fingerprinting System Based on 13 Core SNP Markers

77 garlic accessions were sequenced using reduced-representation genome sequencing to develop a DNA fingerprinting system. A total of 26,701,817 raw SNPs were detected and filtered down to 13 high-quality core markers, which could distinguish 73 out of the 77 accessions. The dataset, authored by Qingqing Yang and last updated in 2026, provides a basis for germplasm identification and molecular breeding.

Use Cases

• Garlic germplasm identification based on SNP-based DNA fingerprinting.
• Variety protection and purity assessment using the 13 core SNP markers.
• Molecular breeding program design leveraging the genotyping results from 77 accessions.
• Population genetics analysis using metrics like minor allele frequency and expected heterozygosity.

Strengths

• Data is derived from reduced-representation genome sequencing of 77 garlic accessions.
• A final set of 13 high-quality core SNP markers was validated for discriminatory power.
• The study reports specific genetic metrics, including an average minor allele frequency of 0.235 and polymorphism information content of 0.227.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 1.1 MB, which may limit the scope of analysis.
