Abstract
The experiment was conducted with objectives of determining the effect of genotype, environment and their interaction for grain yield and to identify the most stable finger millet genotypes in northwestern Ethiopia. Nine finger millet genotypes were grown at six sites in northwestern Ethiopia. The experiment was laid down in RCBD with three replications. The combined ANOVA for grain yield revealed highly significant (P<0.01) for genotypes, environments and their interactions. This indicated that the environments were diverse and variability among the genotypes. The significant interaction showed the genotypes respond differently across the different environments. The mean grain yield value of genotypes averaged over environments indicated that Wama and Padet had the highest (2001 kg ha 1) and lowest (1452 kg ha 1) grain yield respectively. The mean grain yield ranged from 926 kg ha 1 for Sanja to 2329 kg ha 1 for Delgi. In AMMI analysis, AMMI I biplot showed Adet and Delgi were favorable environments; Sanja and Chilga were unfavorable environments while Finoteselam and Merawi were average environments. Within genotypes, Wama, Tadesse, Gute and ACC#203572 have higher average mean yields. In AMMI 2 biplot, Delgi and Finoteselam are the most discriminating environments, while Degu, ACC#203572, Tadesse, Gute and BRC-029-1 are the most responsive genotypes. The best genotype with respect to sites Delgi and Sanja were genotype Gute; for Finoteselam were Boneya and ACC#203572; for Adet and Chilga were Degu and Wama, while genotypes Wama and BRC-029-1 were well fit for Merawi
