A total of ten food barley varieties were evaluated to study their adaptability and yield performance and the combined analysis showed significant differences (p<0.001). Varieties HB-1966 and EH-1493 showed promising results and preferred among the tested varieties. The combined over locations’ grain yield of the varieties ranged from 1589 to 2689 Kg ha-1, while the range was from 1589 to 4713 Kg ha-1. This shows that how big the effect of the environment is on the yield of the varieties. The highest grain yield was recorded for HB-1966 followed by EH-1493, where the lowest yield was recorded for Harbu variety. The principal component analysis of the varieties studied showed that the first two PCAs accounted for 85.17% of the total variability in grain yield. Genotypes 2, 5 and 7 are located near the concentric circle and are likely to be stable among the varieties studied.
