Faba Bean QTL Maps for Morphology, Yield, and Disease Resistance

59 stable quantitative trait loci (QTLs) for faba bean were identified using high-density linkage maps from two recombinant inbred line populations. The maps, comprising 2,043 and 3,903 SNPs, were anchored to a reference genome to refine intervals and prioritize candidate genes like transcription factors and signaling proteins. This dataset, authored by Lorena Barea and last updated in April 2026, provides a genomic framework for marker-assisted breeding.

Use Cases

• Prioritizing candidate genes for marker-assisted selection based on overlapping genomic regions identified in the study.
• Conducting colocalization analyses of QTLs for morphology, yield, and biotic resistance traits.
• Validating previously reported QTL and GWAS data by projecting findings onto a physical reference genome.
• Investigating potential pleiotropic effects linking yield components with disease resistance traits.

Strengths

• Dataset is derived from two high-density linkage maps with 2,043 and 3,903 SNPs, providing improved resolution over previous studies.
• QTL detection was supported by high heritability and coherent phenotypic correlations across multiple environments and years.
• Integration with a reference genome refined 16 overlapping genomic regions containing between 2 and 596 genes for cross-validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• The dataset is small (157.2 KB), indicating a limited scope focused on summary QTL and gene mapping results rather than raw phenotypic or genotypic data.
