Genotype X Environment Interaction by AMMI and GGE-Biplot Stability Analysis in Grain Yield for Soybean [(Glycine Max L.) Merrill] in Ethiopia

Abstract

Soybean (Glycine max L. Merrill), popularly and often called “miracle bean” as it is extraordinarily rich in protein (~40%) and oil (~20%). It is the world's foremost provider of high-quality protein and edible oil for both human food and animal feed; in addition, it can improve soil fertility through its capability to fix atmospheric nitrogen (Morsy et al., 1990). It contains well balanced 40% protein (Lysin rich) and 20 % oil enriched with essential fatty acids.
