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

A 16.3 KB dataset from figshare, last updated on 2026-04-22, documents genomic regions associated with stripe rust resistance in wheat. Author Jianming Hu identified a quantitative trait locus (QTL) on chromosome 3A, QYr.cib-3AS, explaining 20.10%–25.21% of phenotypic variance. The data supports marker-assisted breeding by detailing candidate genes and the enhanced resistance from pyramiding QYr.cib-3AS with YrT14.

Use Cases

• Identifying candidate genes for stripe rust resistance based on annotated high-confidence genes in the QTL interval.
• Evaluating the additive effect of pyramiding resistance QTLs based on the described 77.20% increase in resistance.
• Designing molecular markers for breeding programs based on the delimited interval flanked by dCAPS-78 and dCAPS-83.
• Prioritizing genes for functional validation using integrated transcriptome and sequence variation analysis.

Strengths

• Quantitative trait locus (QTL) QYr.cib-3AS was consistently detected across environments with a reported LOD score range of 2.57–3.58.
• The dataset provides a specific phenotypic variance explanation range of 20.10%–25.21% for the identified QTL.
• Pyramiding analysis shows a concrete 77.20% increase in resistance relative to lines lacking both QTLs.
• Candidate interval is annotated with 48 high-confidence genes, narrowing the search for underlying resistance genes.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 16.3 KB, indicating limited scope, likely a summary table rather than raw genomic data.
