Wild Bilberry Phenolic Compounds and GWAS Results

A 2026 study identified 24 phenolic compounds in wild bilberry (Vaccinium meridionale Swartz) across 118 genotypes, ripe fruit, and leaf samples using RP-UHPLC-DAD and ESI-QTOF-MS/MS. Genome-wide association studies using 16,709 SNPs across 69 genotypes revealed 40 significant QTNs associated with seven compounds. The dataset, authored by Carlos-Eduardo Narváez-Cuenca, provides molecular targets for breeding programs.

Use Cases

• Identify genetic markers for phenolic compound biosynthesis based on GWAS results with 40 QTNs.
• Compare phenolic profiles between fruit and leaf tissues based on quantified compound abundances.
• Analyze the genetic architecture of flavonoid regulators like MYB transcription factors based on candidate gene associations.
• Assess the nutritional potential of wild bilberry genotypes based on quantified anthocyanin and nonanthocyanin compounds.

Strengths

• Quantified concentrations for 24 identified phenolic compounds, with specific ranges provided for major constituents.
• Genetic analysis based on 16,709 high-quality SNPs across 69 genotypes, identifying 40 significant QTNs.
• Includes data from multiple sample types: a control ripe fruit, 118 genotypes, green leaves, and purple leaves.

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 243.7 KB size suggests a limited scope, likely containing summary or aggregated results rather than raw measurements.
