Genetic Parameters and Selection Gain in 34 Tropical Wheat F2 Populations

Tropical wheat breeding data from a study estimating genetic parameters and selection gain via Bayesian inference. The dataset includes grain yield per plot for 34 F2 populations, with heritability estimated at 0.51 and a genetic gain of 7.80% for selected populations. The research was authored by Henrique Caletti Mezzomo and is available via Open Access.

Use Cases

• Estimating heritability and genetic gain based on grain yield data from F2 populations.
• Comparing the performance of different wheat populations against control cultivars.
• Applying Bayesian inference methods to model genetic parameters in plant breeding trials.
• Identifying promising parental lines for future wheat cultivar development.

Strengths

• Includes specific genetic parameter estimates: heritability (h2) of 0.51.
• Reports a concrete genetic gain figure of 7.80% for selected populations.
• Identifies five specific promising wheat populations by name.
• Data is derived from a defined experimental scope: 34 F2 populations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect the specific experimental bias inherent to the single study described.
