Genomic Variation and Trait Associations for 180 Bitter Gourd Accessions

180 bitter gourd accessions were whole-genome re-sequenced, generating an average coverage of 33.91× and identifying ~1.78 million high-quality SNPs. The dataset, authored by Chengcheng Feng and last updated in April 2026, includes phenotypic data for four key horticultural yield traits and results from genome-wide association studies (GWAS).

Use Cases

• Conducting population structure analysis based on the identified ~1.78 million SNPs.
• Performing genome-wide association studies (GWAS) for fruit weight, length, diameter, and flesh thickness.
• Identifying candidate genes and haplotypes for marker-assisted selection based on the reported significant loci.
• Analyzing linkage disequilibrium decay patterns across the five identified sub-populations.

Strengths

• Includes whole-genome re-sequencing data for a diverse panel of 180 bitter gourd accessions.
• Provides an average sequencing coverage of 33.91× and ~1.78 million high-quality SNPs.
• Contains phenotypic measurements for four key horticultural yield traits linked to genomic data.
• Identifies specific candidate genes and haplotypes with quantified effects on fruit traits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is a PDF, which may require extraction for computational analysis.
