Abstract

In order to select adapted and high yield barley varieties, regional yield trials were carried out using a RCBD design with 24 barley genotypes in Maragheh, Ardebil, Zanjan and with 22 genotypes in all locations Maragheh, Ardebil, Kermanshah, Kordistan, Shirvan and Zanjan. These experiments were conducted with four replications in three years (2001-2004). Simple and combined analyses of variance in all locations were done separately. Fmax Hartely used to assess the homogeneity of the error variance at various, showed that the errors variance were homogeneous. Combined analyses were done once with 22 genotypes in all rejoins then with 24 genotypes in Maragheh, Ardebil, Zanjan stations. The results showed that there were significant differences (P1 %
