Sorghum Salt Tolerance Scores for 100 Accessions Under Stress

A 2026 study by Hong-jin Wang evaluated germination and early growth responses in 100 sorghum accessions under control and 150 mM NaCl conditions. Multiple indices were used to develop a numeric salt tolerance score (STS), minimizing baseline growth effects. Multivariate approaches, including PCA, cluster analysis, and machine learning, were employed to assess salt tolerance.

Use Cases

• Ranking sorghum accessions for salt tolerance based on the numeric STS score.
• Analyzing correlations between physiological traits (e.g., sodium accumulation, K+/Na+ ratios) and germination performance.
• Training machine learning models to predict salt tolerance from multivariate germination trait data.
• Identifying candidate genes (e.g., SbNHXLP, SbHKT1;4) associated with ion homeostasis in tolerant accessions.

Strengths

• Includes data from 100 sorghum accessions.
• Tests germination under a specific 150 mM NaCl stress condition.
• Employs multivariate analysis including PCA, cluster analysis, and machine learning.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is stored as a DOCX file (749.4 KB), which likely contains textual tables rather than a structured data format.
