Bitter Gourd Genomic Variation Map for 180 Accessions

A 2026 study by Chengcheng Feng presents whole-genome re-sequencing data for 180 bitter gourd accessions. The dataset includes approximately 1.78 million high-quality SNPs and phenotypic measurements for four key horticultural yield traits. It serves as a foundational genomic resource for molecular breeding programs.

Use Cases

• Conducting genome-wide association studies (GWAS) based on the identified ~1.78 million SNPs and phenotypic data
• Analyzing population structure and genetic diversity across the five identified sub-populations
• Identifying candidate genes and haplotypes for traits like fruit weight, length, and diameter based on the reported significant loci
• Validating genetic markers for fruit flesh thickness using the haplotype partitioning results

Strengths

• Includes a substantial number of genetic variants, with ~1.78 million high-quality SNPs identified
• Covers a diverse panel of 180 bitter gourd accessions, providing a broad genetic base
• Links genomic data to four key measured horticultural traits, enabling genotype-phenotype association
• Identifies specific candidate genes and haplotypes with quantified phenotypic effects (e.g., 20.46%—22.68% increase in 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 is presented in a PDF format (1.4 MB), which may require extraction for computational analysis
