Abstract: Barley, an important cereal crop in Afghanistan, has low productivity. To identify high yielding and stable genotypes, an evaluation of nine barley inbred lines and a national check was conducted for yield and its stability at 6 diverse environments in Afghanistan. Experiments were designed to determine genotype (G) × environment (E) interaction (GEI) effect on grain yield using AMMI model and to identify the high yielding and stable barley genotypes. The main effect of G and GEI were highly significant (P<0.01) on grain yield. The E, G, and GEI accounted for 75.0%, 7.5% and 8.2% of variation in grain yield. Based on the AMMI stability parameters, line G9 was the most stable lines across environments with above average grain yield and will be recommended as a candidate for the consideration of the Varietal Release Committee in Afghanistan.
