AGD-R: Statistical Analysis Programs for Diallel Mating Designs in Genetics

AGD-R is a set of R programs for statistical analysis of genetic experiments, created by Francisco Rodríguez. It performs calculations for Diallel, Line by Tester, and North Carolina mating designs to assess genetic and environmental contributions to quantitative traits. The software includes a graphical Java interface for user input and analysis selection.

Use Cases

• Assessing genetic versus environmental variance in observed traits based on the description of diallel designs.
• Determining the number of major genetic factors for a quantitative trait based on the described biometrical genetics objective.
• Analyzing data from specific experimental designs like North Carolina or Line by Tester based on the listed analysis capabilities.

Strengths

• Software is designed for a specific, well-established family of genetic experimental designs (Diallel, Line by Tester, North Carolina).
• Includes a graphical Java interface to facilitate user interaction with the analysis programs.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
