Ammi Analysis of Yield Performance and Stability of Finger Millet Genotypes Across Different Environments

Abstract

3 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 ) and lowest (1452 kg ha ) grain yield 11
