QYr.cib-3AS and YrT14: Wheat Stripe Rust Resistance QTL Data

Two genomic regions associated with stripe rust resistance in wheat were identified using BSA-seq and QTL mapping with a 120K SNP array. The QTL QYr.cib-3AS on chromosome 3A explained 20.10%–25.21% of phenotypic variance and was delimited to a specific interval containing 48 high-confidence genes. This dataset, authored by Jianming Hu and last updated in April 2026, provides a foundation for cloning resistance genes and developing elite wheat cultivars.

Use Cases

• Prioritize candidate genes for stripe rust resistance based on the 48 annotated genes in the QTL interval.
• Design molecular markers for breeding programs using the delimited interval flanked by dCAPS-78 and dCAPS-83.
• Study the additive effect of pyramiding resistance genes based on the reported 77.20% increase in resistance.
• Validate QTL mapping results in different wheat genetic backgrounds using the identified SNP array data.

Strengths

• The QTL QYr.cib-3AS was consistently detected across environments with a reported LOD score range of 2.57–3.58.
• The candidate interval is precisely delimited and contains 48 high-confidence annotated genes.
• The dataset quantifies the additive effect of gene pyramiding, showing a 77.20% increase in resistance.

Limitations

• The dataset is very small at 15.6 KB, suggesting limited raw data or a summary document.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
