Bitter Gourd Genomic Variation Map for 180 Accessions with Horticultural Trait Data

A genomic dataset from whole-genome re-sequencing of 180 bitter gourd (Momordica charantia L.) accessions, identifying approximately 1.78 million high-quality SNPs. The data includes phenotypic measurements for four key horticultural yield traits and results from genome-wide association studies (GWAS) mapping these traits to specific loci. The dataset was authored by Chengcheng Feng and published on figshare in April 2026.

Use Cases

• Conducting population genetics analysis based on the identified ~1.78 million SNPs and five distinct sub-populations.
• Identifying candidate genes for fruit weight, length, and diameter based on the major pleiotropic region on chromosome MC04.
• Investigating haplotype effects on fruit flesh thickness using the described haplotype partitioning results.
• Validating trait-specific loci for single fruit weight on MC08 and fruit flesh thickness on MC09.
• Developing molecular markers for breeding programs based on the GWAS-identified significant loci and haplotype information.

Strengths

• Includes genomic data from 180 diverse bitter gourd accessions with an average sequencing coverage of 33.91×.
• Provides a high-quality variation map with approximately 1.78 million single nucleotide polymorphisms (SNPs).
• Links genomic data to measured phenotypic traits for four key horticultural yield characteristics.
• Identifies specific candidate genes and haplotypes with quantified phenotypic effect sizes (e.g., 20.46%—22.68% increase in single fruit weight).

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 file is a 1.4 MB PDF, which may require extraction or conversion for computational analysis.
