Selection of durum wheat genotypes with wide adaptability across various environments is important before
recommending them to reach a high rate of genotype adoption. Multi-environment grain yield trials of 20
durum wheat genotypes were conducted at five locations of Iran (Gachsaran, Gonbad, Moghan, Ilam and
Khorram abad) over four years (2009-2013). Combined ANOVA of yield data of the 20 environments revealed
highly significant differences among genotypes and environments as well as significant GE interaction
indicated differential performance of genotypes over test environments. Results of F Ratio indicated that only
five interaction principal components (IPCs) were significant at the 0.01 probability level. Also, the GE
interaction is comprised of 29.7% noise and 70.03% signal. According to these distinct numbers of significant
axes, fourteen AMMI stability parameters were computed. Finally according to the most of type 1 of AMMI
parameters (EV1, AMGE1, SIPC1 and D1), genotypes G8, G17 and G11; based on the type 2 of AMMI
parameters and ASV, genotypes G4, G5, G10, G11 and G17; due to type 3 of AMMI parameters and MASV,
genotypes G8, G10 and G12 were detected as the most stable genotypes. Considering all of the AMMI stability
parameters, genotypes G8, G10, G11, G12 and G17 following to genotypes G7 and G9 were the most stable
genotypes. The best recommended genotypes according to the present study are G10 with 3470 kg ha-1 grain
yield for Gachsaran and Khorramabad, G12 with 3343 kg ha-1 grain yield for Ilam and G10 and G12 for
Moghan and Gonbad regions wich had high mean yield and were most stable for related mega-environments.
