Soybean Saline-Alkaline Stress Tolerance GWAS for 198 Accessions

A study by Ming Yuan evaluated saline-alkaline stress tolerance in a core panel of 198 soybean accessions at the germination stage, focusing on four germination-related traits. Whole-genome resequencing generated 385,087 high-quality SNPs, and a genome-wide association study identified 428 candidate genes. The dataset, last updated in May 2026, provides a theoretical foundation for breeding saline-alkaline tolerant soybean cultivars.

Use Cases

• Identify candidate genes for saline-alkaline stress tolerance based on GWAS results and SNP data.
• Analyze genetic diversity for stress adaptability based on phenotypic variation among 198 soybean accessions.
• Validate previously reported salinity tolerance genes like GmLecRlk and GmERF34 using the provided genomic data.
• Characterize superior haplotypes associated with improved tolerance, such as those for Glyma.07G004400 and Glyma.15G022000.

Strengths

• Phenotypic evaluation of 198 soybean accessions provides a substantial sample for genetic diversity analysis.
• Genomic data includes 385,087 high-quality single nucleotide polymorphisms (SNPs) for association mapping.
• The study successfully validated two previously reported salinity tolerance-related genes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (707.1 KB), suggesting it may contain summary results or a document rather than raw genomic data tables.
• Row count is unknown, which may limit suitability assessment for large-scale computational analysis.
