Genomic and Phenotypic Data for 180 Bitter Gourd Accessions

Chengcheng Feng's dataset provides whole-genome re-sequencing data for 180 bitter gourd accessions, published on figshare in April 2026. It includes approximately 1.78 million high-quality SNPs and phenotypic measurements for four key horticultural yield traits. The data was used for population structure analysis and genome-wide association studies to identify genetic loci linked to fruit traits.

Use Cases

• Conducting genome-wide association studies based on the ~1.78 million SNPs and four measured fruit traits
• Analyzing population structure and genetic diversity across the five identified sub-populations
• Investigating haplotype effects on fruit weight, length, and diameter using the candidate genes on chromosome MC04
• Identifying trait-specific genetic markers for fruit flesh thickness using loci on chromosome MC09

Strengths

• Includes genomic data for a diverse panel of 180 bitter gourd accessions
• Provides an average sequencing coverage of 33.91×, which is substantial for variant calling
• Identifies approximately 1.78 million high-quality single nucleotide polymorphisms (SNPs)
• Links genomic data to four key phenotypic traits: single fruit weight, fruit length, fruit diameter, and fruit flesh thickness

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 small (162.5 KB), suggesting it may contain summary or processed results rather than raw sequencing reads
