META-R: Statistical Analysis for Multi-Environment Plant Breeding Trials

META-R is a set of R programs for statistical analysis of plant breeding trials. It calculates BLUEs, BLUPs, genetic correlations, and broad-sense heritability, and can generate boxplots and histograms. The software was authored by Gregorio Alvarado and includes a graphical Java interface for user interaction.

Use Cases

• Calculate Best Linear Unbiased Estimators (BLUEs) for genotype performance across locations.
• Estimate Best Linear Unbiased Predictors (BLUPs) for genetic merit of breeding lines.
• Compute genetic correlations among trial locations or between measured traits.
• Estimate broad-sense heritability for traits measured in breeding trials.
• Generate visual summaries like boxplots and histograms for trial data analysis.

Strengths

• Software performs a specific suite of statistical analyses relevant to plant breeding.
• Includes a graphical Java interface to facilitate user interaction with the analysis programs.

Limitations

• The dataset's specific row count, column structure, and file formats are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
