Genomic Re-sequencing of 180 Bitter Gourd Accessions with Horticultural Trait Data

A 2026 study by Chengcheng Feng presents whole-genome re-sequencing data for a diverse panel of 180 bitter gourd accessions. The data includes approximately 1.78 million high-quality SNPs and phenotypic measurements for four key yield-related traits, supporting genome-wide association studies. This foundational resource is intended to accelerate molecular breeding programs for this cucurbit crop.

Use Cases

• Conducting population genetics analysis based on the identified ~1.78 million SNPs and five delineated sub-populations.
• Performing genome-wide association studies for fruit weight, length, diameter, and flesh thickness based on the phenotyped panel.
• Identifying candidate genes and haplotypes for marker-assisted selection, based on loci like those on chromosomes MC04, MC08, and MC09.
• Investigating linkage disequilibrium decay patterns across different genetic subgroups of bitter gourd.

Strengths

• Includes genomic data for 180 diverse accessions with an average sequencing coverage of 33.91×.
• Identifies approximately 1.78 million high-quality single nucleotide polymorphisms (SNPs).
• Phenotypic data is provided for four key horticultural traits: single fruit weight, fruit length, fruit diameter, and fruit flesh thickness.
• Analysis reveals specific candidate genes and haplotypes with quantified phenotypic effects, such as a 20-22% 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 file is a 1.4 MB PDF, which may require extraction and conversion for computational analysis.
