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

Chengcheng Feng published a dataset on figshare in April 2026 containing whole-genome re-sequencing data for 180 bitter gourd accessions. The data includes approximately 1.78 million high-quality SNPs and phenotypic measurements for four key horticultural yield traits. This resource was created to uncover the genetic basis of traits like fruit weight and length.

Use Cases

• Conducting genome-wide association studies (GWAS) based on the ~1.78 million SNPs and trait phenotypes
• Analyzing population structure and genetic diversity across the five identified sub-populations
• Identifying candidate genes and haplotypes for fruit-related traits like weight, length, and diameter
• Investigating pleiotropic genetic regions, such as the one on chromosome MC04 associated with multiple traits

Strengths

• Includes whole-genome re-sequencing data for a diverse panel of 180 bitter gourd accessions
• Provides an average sequencing coverage of 33.91×, which suggests high data depth
• Identifies approximately 1.78 million high-quality single nucleotide polymorphisms (SNPs)
• Links genomic data to measured phenotypes for four key horticultural yield 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 file is a PDF (1.5 MB), which may not be in an immediately machine-readable format for analysis
