Phenolic Compounds and GWAS Results for 118 Wild Bilberry Genotypes

A dataset of 24 anthocyanin and nonanthocyanin phenolic compounds identified in wild bilberry (Vaccinium meridionale Swartz) fruit and leaf samples from 118 genotypes. The data includes compound concentrations and results from a genome-wide association study (GWAS) using 16,709 SNPs across 69 genotypes, identifying 40 quantitative trait nucleotides. The dataset was created by Carlos-Eduardo Narváez-Cuenca and last updated in June 2026.

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 concentrations.
• Investigate candidate genes like MYB transcription factors linked to flavonoid biosynthesis.
• Analyze the variation of major compounds like chlorogenic acid across a population of 118 genotypes.

Strengths

• Identifies 24 specific phenolic compounds with concentration ranges provided (e.g., chlorogenic acid 223.5–2539.8 mg/100g DW).
• GWAS analysis is based on 16,709 high-quality SNPs across 69 genotypes.
• Analysis includes multiple sample types: control ripe fruit, 118 genotypes, green leaves, and purple leaves.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is small (41.5 KB), indicating limited scope and likely a summary or results table rather than raw experimental data.

Collection Method

Compounds were identified using reversed-phase ultrahigh-performance liquid chromatography with diode array detection (RP-UHPLC-DAD) and RP-UHPLC with electrospray ionization, quadrupole-time-of-flight tandem mass spectrometry (ESI-QTOF-MS/MS).
