Abstract

The objective of this paper is to identify stable and high yielding varieties among 20 Ethiopian Bread wheat (Triticum aestivum L.) genotypes on the basis of experiments conducted during the 2007 and 2008 growing seasons. The additive main effects and multiplicative interaction (ammi) model has been used to estimate G×E interaction and also to identify stable genotypes in environments. Combined anova of G×E indicated the presence of significant interactions, as well as significant differences between genotypes and environments. According to AMMI, model genotypes G11, G10, G5 and G12 are found stable. In graphical display of the biplot, Adet is categorized under high yielding wheat environment as compared to the three relatively low yielding categorized environments (Holeta, Kulumsa and Sinana).
