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

A high-density genetic linkage map containing 4,035 representative bin markers across 13 linkage groups was constructed from an F2 population of 147 ridge gourd plants. The dataset, authored by Qin Chen and last updated in May 2026, identifies eight significant QTLs for early-maturity traits, with a major hotspot anchored to a 7.03 Mb interval on chromosome 3.

Use Cases

• Fine-mapping candidate genes based on the identified 7.03 Mb QTL hotspot interval.
• Prioritizing candidate genes like Lac03g1231 and Lac03g1281 for functional validation.
• Designing marker-assisted breeding strategies based on the eight identified QTLs.
• Comparing genetic architecture of maturity traits across cucurbit species using the high-density linkage map.

Strengths

• High-density 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.
• The dataset is very small (5.3 KB), suggesting it contains summary results rather than raw sequence data.
