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

Table 2_The pyramiding of QYr.cib-3AS and YrT14 enhances wheat resistance to stripe rust.docx contains data from a study identifying quantitative trait loci (QTL) for stripe rust resistance in wheat. The dataset was authored by Jianming Hu and last updated on 2026-04-22. It includes results from BSA-seq and QTL mapping using a 120K SNP array, detailing a major QTL on chromosome 3A and its pyramiding effect with another resistance locus.

Use Cases

• Identifying candidate genes for stripe rust resistance based on annotated high-confidence genes in the QTL interval.
• Assessing the additive effect of pyramiding resistance loci (QYr.cib-3AS with YrT14) on phenotypic variance.
• Designing markers for assisted breeding using the delimited interval flanked by dCAPS-78 and dCAPS-83.
• Validating QTL mapping results across different environments based on reported LOD scores and phenotypic variance explained.

Strengths

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

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (19.2 KB), indicating limited scope, likely a single summary table.
