WAMI Panel: 153 Spring Wheat Genotypes Under Heat Stress in Iran, 2020-2022

Field trial data from the 2020–2021 and 2021–2022 growing seasons at the Isfahan University of Technology research farm in Iran. The dataset evaluates 153 elite spring wheat genotypes from the Wheat Association Mapping Initiative (WAMI) panel and three controls under simulated terminal heat stress conditions. Author Vahid Rezaei published the data on figshare under a CC-BY-4.0 license.

Use Cases

• Identify heat-tolerant wheat genotypes based on stress tolerance indices (STI, MP, YSI, HSI) described in the study.
• Analyze the impact of heat stress on phenological traits like days to flowering, anthesis, and maturity.
• Model the relationship between grain yield loss under heat stress and stable flour-quality traits such as the Zeleny index.
• Rank genotypes for breeding programs based on combined yield potential and heat resilience, as demonstrated for lines 029, 123, 104, 067, and 139.

Strengths

• Data covers two full growing seasons (2020–2021 and 2021–2022) for temporal replication.
• Includes 153 elite genotypes plus three controls, providing considerable genotypic variability.
• Measures multiple agronomic (e.g., grain yield, grain-filling period) and quality traits (e.g., Zeleny index) under two sowing conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to a single research farm in Iran, which may reflect geographic bias.
