Abstract

The present investigation was carried out to assess the phenotypic stability of grain yield and its contributing characters under eight different environmental conditions for 12 barley genotypes. Grain yield in different locations shows that Sakha and Gimmeza locations produced the highest grain yield (5.84 and 5.56) t/ha respectively. According to stability parameters (bi, S2d, R2i)   and average yield results revealed that L9, L10 promising lines and Giza 128 cultivar showed average stability with general adaptability. However, L1 and L8 were adapted to high yielding environments. On the other side, L2, L5 and L3 promising lines were adapted to low yielding environments.
