High-Density SNP Linkage Map and QTL Hotspot for Early Maturity in Ridge Gourd

A genetic study of ridge gourd (Luffa acutangula) developed an F₂ population of 147 plants from a cross between lines contrasting in early maturity. Qin Chen published this dataset on figshare in 2026, containing a high-density genetic linkage map with 4,035 bin markers across 13 linkage groups and identifying eight significant QTLs.

Use Cases

• Fine mapping of candidate genes based on the identified 7.03 Mb QTL hotspot interval on chromosome 3.
• Marker-assisted breeding for early maturity traits using the 4,035 representative bin markers.
• Prioritizing candidate genes like Lac03g1231 and Lac03g1281 for functional validation studies.
• Comparative genomics analysis by aligning the constructed linkage map to a reference genome.

Strengths

• High-density genetic map constructed from 4,035 representative bin markers.
• Analysis based on whole-genome resequencing of two parents and 144 F₂ individuals.
• Identifies a major multi-trait QTL hotspot anchored to a specific 7.03 Mb genomic interval.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is specific to a single F₂ population of ridge gourd, limiting generalizability.
