Haplotyping and Admixture Results for 390 Saccharum Accessions and Related Genera

Simon Rio from CIRAD Harvested Collection published this dataset on 2026-06-06. It contains haplotype presence-absence data for 390 sugarcane accessions and related genera, genotyped for over 3.8 million haplotypes. The data includes genome-wide admixture proportions for six ancestral groups and local ancestry dosages for 117 cultivars.

Use Cases

• Study population structure and ancestry based on admixture proportions for six ancestral groups
• Analyze haplotype diversity and presence-absence patterns across 390 accessions
• Investigate local ancestry patterns in cultivars using dosage data for 80K markers
• Compare genomic diversity between Saccharum species and related genera like Miscanthus and Erianthus

Strengths

• Includes data for a large diversity panel of 390 accessions
• Provides haplotype presence-absence information for over 3.8 million haplotypes
• Contains admixture analysis results for six defined ancestral groups

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
