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

Jianming Hu published data on genomic regions associated with stripe rust resistance in wheat. The dataset includes results from BSA-seq and QTL mapping using a 120K SNP array, identifying a key QTL on chromosome 3A explaining 20.10%–25.21% of phenotypic variance. The data was last updated on 2026-04-22.

Use Cases

• Identifying candidate genes for stripe rust resistance based on annotated genomic intervals.
• Assessing the additive effect of pyramiding resistance QTLs based on the described phenotypic variance analysis.
• Developing molecular markers for breeding based on the delimited interval flanked by dCAPS markers.

Strengths

• The QTL QYr.cib-3AS was consistently detected across environments, explaining 20.10%–25.21% of phenotypic variance.
• The pyramiding of QYr.cib-3AS with YrT14 increased stripe rust resistance by 77.20% relative to lines lacking both.
• The candidate interval contains 48 high-confidence annotated genes, with two identified as key candidates.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 16.0 KB, indicating limited scope.
