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

Table 1_The pyramiding of QYr.cib-3AS and YrT14 enhances wheat resistance to stripe rust.docx contains data from a study identifying quantitative trait loci for stripe rust resistance in wheat. The dataset, authored by Jianming Hu and last updated on 2026-04-22, includes results from BSA-seq and QTL mapping using a 120K SNP array. It reports a QTL on chromosome 3A explaining 20.10%–25.21% of phenotypic variance and a 77.20% increase in resistance from pyramiding two loci.

Use Cases

• Identifying candidate genes for stripe rust resistance based on annotated high-confidence genes in the candidate interval.
• Validating marker-assisted selection strategies using the delimited interval flanked by dCAPS-78 and dCAPS-83.
• Analyzing the additive effects of pyramiding resistance loci based on the reported 77.20% increase in resistance.
• Studying genomic collinearity in wheat resistance regions as suggested by the candidate interval analysis.

Strengths

• Quantitative results are provided, including a QTL explaining 20.10%–25.21% of phenotypic variance with LOD scores of 2.57–3.58.
• The study reports a specific, measurable effect: a 77.20% increase in resistance from pyramiding two loci.
• Candidate genes are narrowed down to 48 high-confidence annotations, with two key candidates suggested.

Limitations

• The dataset is very small (15.5 KB), suggesting it is likely a summary table rather than raw genomic data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical analysis.
