ammistability: Genotype Stability Parameters from AMMI Analysis

A computational package for calculating stability parameters from Additive Main Effects and Multiplicative Interaction (AMMI) analysis. It implements methods such as Modified AMMI Stability Value (MASV), AMMI Stability Index (ASI), and Annicchiarico's D Parameter (DA), and computes a Simultaneous Selection Index for Yield and Stability. The package was authored by B. C. Ajay and is hosted on the paperswithcode platform.

Use Cases

• Selecting stable crop genotypes based on computed stability parameters like MASV and ASI.
• Analyzing genotype-by-environment interaction patterns using AMMI-derived metrics such as SIPC and AMGE.
• Ranking genotypes for simultaneous yield and stability performance using the integrated Simultaneous Selection Index.

Strengths

• Implements a wide range of established stability parameters, including MASV, ASI, and DZ.
• Provides a unified method for calculating a Simultaneous Selection Index for Yield and Stability.
• Includes a vignette with citations for the implemented methods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
