Ridge Gourd QTL Hotspot: High-Density Linkage Map and Early-Maturity Traits

A high-density genetic linkage map for ridge gourd (Luffa acutangula) contains 4,035 bin markers across 13 linkage groups. It was constructed from whole-genome resequencing of 144 F₂ individuals and identifies eight significant QTLs, including a major multi-trait hotspot on LG3. The dataset was authored by Qin Chen and last updated on May 28, 2026.

Use Cases

• Identifying candidate genes for early maturity based on the annotated 136 genes within the 7.03 Mb hotspot interval.
• Conducting comparative genomics studies using the high-density linkage map containing 4,035 representative bin markers.
• Supporting marker-assisted breeding programs for ridge gourd by leveraging the eight significant QTLs identified.
• Performing fine-mapping and functional validation studies guided by the prioritized candidate genes Lac03g1231 and Lac03g1281.

Strengths

• The genetic map is high-density, containing 4,035 representative bin markers.
• QTL analysis is based on phenotypic evaluation of six traits across a population of 147 F₂ plants.
• A major multi-trait QTL hotspot is 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 for certain analyses.
• The dataset is very small (6.3 KB), suggesting it contains summary or key results rather than raw sequencing data.
