Soybean Pod Number QTLs Identified via Linkage and GWAS Analysis

A 20.5 KB Excel file contains quantitative trait loci (QTL) mapping results for pod number in soybean. The data was generated by author Yajun Xiong from a recombinant inbred line population derived from a cross between cultivated and wild soybean, with analysis last updated on 2026-06-03. It includes 16 identified QTLs and two candidate genes (Glyma.10G206300 and Glyma.10G207500) linked to traits like flower number and flowering time.

Use Cases

• Identifying major-effect QTL regions for pod number based on overlapping genomic intervals from linkage analysis and GWAS.
• Investigating candidate gene functions (bHLH transcription factor and ARM-repeat protein) for traits influencing soybean yield.
• Comparing QTL detection methods (linkage analysis vs. EMMAX-based GWAS) for the same phenotypic trait in a multi-environment study.

Strengths

• Identifies 16 specific QTLs associated with pod number, providing concrete genetic targets.
• Integrates phenotypic data from a recombinant inbred line population evaluated in multiple environments.
• Points to two specific candidate genes (Glyma.10G206300 and Glyma.10G207500) with proposed functional annotations.

Limitations

• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (20.5 KB), indicating limited scope, likely containing summary results rather than raw data.
