Wheat Stomatal Anatomy and Physiology QTLs from Multi-Environment Field Trials

Field trials across two growing seasons examined stomatal traits in 200 and 50 wheat genotypes under heat stress. The dataset includes measurements of stomatal conductance, anatomical traits like size and density, and grain yield, alongside 62 identified quantitative trait loci. The data was published by Edward Chaplin on figshare in May 2026.

Use Cases

• Identifying genomic regions for heat tolerance based on 62 detected QTLs for stomatal traits.
• Analyzing the decoupling of stomatal anatomical potential from physiological performance under heat stress.
• Studying genotypic variation and heritability in stomatal anatomical traits across wheat cultivars.
• Comparing adaxial and abaxial leaf surface contributions to gas exchange using conductance and density measurements.

Strengths

• Data is derived from multi-environment field trials conducted over two years.
• Includes measurements from 200 genotypes in one season and 50 in another, providing a scale for genetic analysis.
• Identifies 62 putative QTLs, with 21 consistent with previously reported chromosomal regions.

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 an 11.0 MB PDF, which may require extraction to access structured data.
