Summary

Key Findings

  • 758,496 CNVs detected genome-wide across 11 chromosomes in 219 bottle gourd accessions
  • Cohort of 80 landraces and 139 F2 populations capturing broad genetic diversity
  • Dominant deletion bias with a ~21:1 deletion-to-duplication ratio across all chromosomes
  • Overlapping CNVs merged into 9,248 non-redundant CNVRs — a compact structural variation map
  • CNVR type proportions mirror raw CNV ratios, confirming robustness of the merging strategy
