Grain yield and its components of 14 hull-less barley genotypes were evaluated in two seasons (2013/2014 and 2014/2015) in five locations (Nubaria, Sakha, Gimmeza, Quntra sharq and Giza) in Egypt. Grain yield ranged from 3.96 to 6.56 t/ha for "L6" and "L3" promising lines. respectively, with grand average of 5.11 t/ha. Giza 135, Giza 136 cultivar
L3and L2 promising line produced highest grain yield and its components. On the other hand, the least genotype "L6" in grain yield was had least values in most yield and its components.
Pooled analysis of variance revealed significant effect of S x L interaction and the seasons had greater effect than location, Results also showed significant G x S x L interaction, this means there were differences in relative performance of genotypes over season-location combinations or in other word there were changes genotype x location effect among seasons.
According to stability parameters (bi, S2d, R2, C.V %) and yield average results revealed that L2, L3, L6 promising lines and Giza 135 and Giza 136 showed average stability with general adaptability. However, L8, Giza 129 and Giza 131 were adapted to high yielding environments. On the other side, L4, LS'" and L 7 promising lines are adapted to low yielding environments
