Pengembangan aplikasi AMMI dengan antarmuka ramah pengguna menggunakan R

Abstract

AMMI (Additive Main Effect Multiplicative Interaction) model for interactions in two-way table provide the major mean for studying stability and adaptability through genotype × environment interaction (GEI). This study aimed to build a “user friendly” program to analyze AMMI called AMMIR (Additive Main Effect Multiplicative Interaction in R). The data used in this study was from “Konsorsium Padi Nasional” research and “Balai Penelitian Kacang- kacangan dan Umbi-umbian (Balitkabi) Departemen Pertanian RI” research. AMMIR performed a good result compare to other programs such as SAS, IrriStat and GenStat. The result showed that output AMMIR such as biplot and analysis of variance are exactly the same as the other programs.
