Wild Bilberry Phenolic Compounds and Genetic Associations

24 phenolic compounds were identified in wild bilberry (Vaccinium meridionale Swartz) fruit and leaves using RP-UHPLC-DAD and ESI-QTOF-MS/MS. The dataset includes concentration ranges for compounds like chlorogenic acid (223.5–2539.8 mg/100g DW) and results from a GWAS using 16,709 SNPs across 69 genotypes, revealing 40 QTNs. Authored by Carlos-Eduardo Narváez-Cuenca and last updated in June 2026, this work provides molecular targets for breeding programs.

Use Cases

• Identify genetic markers for phenolic compound biosynthesis based on 40 significant QTNs.
• Compare phenolic profiles between fruit and leaf tissues based on quantified compound abundances.
• Investigate the role of candidate genes like MYB transcription factors in flavonoid pathways.
• Assess the nutritional potential of different Vaccinium meridionale genotypes based on compound concentration ranges.

Strengths

• Quantified concentration ranges for 24 specific phenolic compounds, such as chlorogenic acid and cyanidin-3-O-galactoside.
• GWAS analysis conducted using 16,709 high-quality SNPs across 69 genotypes, identifying 40 significant QTNs.
• Analytical methods include RP-UHPLC-DAD and ESI-QTOF-MS/MS, suggesting detailed compound identification.

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 109.3 KB size indicates a limited scope, likely containing summary statistics rather than raw observations.
