Abstract

Forty barley lines were evaluated for genotype x environment their interaction with 8 different environments and phenotypic stability for grain yield and its components (spike length, spikelets /spike, spikes/ plant, kernels/spike and 1000-kernel weight). The 8 different environments were the combination between four location; Ras Suds, Maryout, El-Maghara and Siwa and two growing seasons; 2013/2014 and 2014/2015. The results revealed highly significant mean squares due to differences among barley lines, environments and their interactions for all studied traits, indicating that barley lines differed in their response to the changes in environments. The two environments; E5 and E6 (El-Maghara location during the two seasons) produced higher mean values for grain yield and its components than other studied environments. Moreover, the two lines; 37 and 40 were the best lines for grain yield and most its components across different environments. Results of phenotypic stability indicated that the two lines; 32 and 34 were considered as the most desirable and stable for grain yield / plant and its components under a wide range of environments.
