Wheat Salt Tolerance Phenotyping Data from Multi-Gradient Experiment

120 wheat varieties were evaluated under four NaCl concentrations, measuring traits like plant height, root length, germination rate, and salt tolerance index. Jia-nan Huang published this dataset on figshare in April 2026, providing phenotypic rankings validated by physiological and molecular analyses. The dataset likely contains statistical results from ANOVA, correlation, PCA, clustering, and TOPSIS analyses.

Use Cases

• Ranking wheat varieties for salt tolerance based on the calculated Salt Tolerance Index (STI)
• Analyzing genotype-environment interactions based on phenotypic measurements across four salinity levels
• Identifying phenotypic groupings for breeding programs using multivariate analysis results like PCA and hierarchical clustering
• Correlating physiological markers like K+/Na+ ratios and antioxidant activity with growth traits under stress

Strengths

• Data covers 120 wheat varieties, providing a moderate sample size for comparative analysis
• Experiments were conducted under four distinct NaCl concentrations (0, 50, 100, and 150 mM) with two independent replicates
• Analysis includes multiple statistical methods (ANOVA, correlation, PCA, clustering, TOPSIS) and subsequent physiological/molecular validation

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 very small (11.3 KB), suggesting it may contain summary results rather than raw measurements
