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

A genetic linkage map contains 4,035 bin markers across 13 linkage groups for ridge gourd (Luffa acutangula). The dataset results from whole-genome resequencing of two parental lines and 144 F₂ individuals, identifying eight significant QTLs clustered on LG3. It was authored by Qin Chen and last updated on 2026-05-28.

Use Cases

• Marker-assisted breeding for early maturity based on identified QTLs
• Fine mapping of candidate genes based on the anchored 7.03 Mb interval on chromosome 3
• Comparative genomics in cucurbits based on the high-density genetic map
• Prioritizing candidate genes for functional validation based on the annotated Lac03g1231 and Lac03g1281

Strengths

• The high-density genetic map contains 4,035 representative bin markers
• QTL analysis identified eight significant loci, with a major multi-trait hotspot anchored to a 7.03 Mb interval
• The dataset is derived from whole-genome resequencing of two parents and 144 F₂ individuals

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is very small at 6.1 KB, indicating limited scope
