Soybean Pod Number QTL Mapping from Recombinant Inbred Line Population

A recombinant inbred line population derived from a cross between an improved soybean cultivar and wild soybean was used for multi-environment phenotypic evaluation of pod number. Quantitative trait locus mapping identified 16 QTLs associated with pod number, with two candidate genes (Glyma.10G206300 and Glyma.10G207500) proposed as regulators. The dataset was authored by Yajun Xiong and last updated on 2026-06-03.

Use Cases

• Validate QTL regions for pod number based on linkage analysis and GWAS results described in the study
• Investigate candidate gene functions (Glyma.10G206300, Glyma.10G207500) related to flower number and flowering time
• Compare genetic architecture of pod number between cultivated and wild soybean accessions
• Design molecular markers for marker-assisted selection in soybean breeding programs

Strengths

• Identifies 16 QTLs associated with pod number, providing specific genetic targets
• Integrates phenotypic data from multi-environment trials with genotypic data from linkage and association mapping
• Proposes two specific candidate genes with functional annotations for further study
• Published under a permissive CC-BY-4.0 license for reuse

Limitations

• Dataset is very small (29.2 KB), indicating limited scope or summary-level data
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for statistical modeling
