SNPs for GWAS on Dietary Fiber in Colombian Agraz (Vaccinium Meridionale)

16,709 high-quality SNPs from 69 genotypes of Colombian agraz (Vaccinium meridionale) were used in a genome-wide association study. The dataset underpins research identifying 24 QTLs associated with dietary fiber content across 15 chromosomes. It was authored by Ginna Patricia Velasco Anacona and last updated in June 2026.

Use Cases

• Conducting GWAS for dietary fiber traits based on the 16,709 SNP markers
• Identifying candidate genes for marker-assisted selection based on the 24 QTLs mentioned
• Studying the polygenic architecture of fruit quality traits in wild Vaccinium species
• Validating associations for specific biosynthetic pathways like glycosyltransferase activity

Strengths

• Contains 16,709 high-quality SNPs, providing a dense genetic marker set.
• Links phenotypic data for total, insoluble, and soluble dietary fiber from 119 genotypes.
• Identified 24 QTLs across 15 chromosomes, offering specific genetic targets.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the SNP data is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Colombian agraz study population.
