180 Bitter Gourd Accessions Re-sequenced for Horticultural Trait Genetics

180 bitter gourd accessions were whole-genome re-sequenced at an average 33.91× coverage, identifying ~1.78 million SNPs. Chengcheng Feng published this genomic variation map in 2026, linking key fruit yield traits to specific loci and haplotypes through GWAS. The data provides a foundational resource for molecular breeding programs.

Use Cases

• Conducting population genetics analysis based on the delineation of 180 accessions into five sub-populations
• Identifying candidate genes for fruit weight, length, and diameter based on the major pleiotropic region on chromosome MC04
• Performing haplotype analysis to uncover hidden phenotypic effects, such as the link between specific haplotypes and fruit flesh thickness
• Mapping trait-specific loci for single fruit weight on MC08 and fruit flesh thickness on MC09

Strengths

• Contains ~1.78 million high-quality SNPs identified from whole-genome re-sequencing
• Based on a diverse panel of 180 bitter gourd accessions with an average sequencing coverage of 33.91×
• Phenotypic data for four key horticultural yield traits is integrated with genomic data

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 format is PDF, which may require extraction for computational analysis
