Summary

The aim of this investigation was to study the effect of GE-interactions of grain yield of bread wheat using the additive main effects and multiplicative interaction (AMMI) model. Twenty-four genotypes of bread wheat were sown at 13 locations for 3 growing seasons (2006/2007, 2007/2008 and 2008/2009). The results showed that main effects due to E, G, and GE interaction were found to be significant (P<0.01). The GGE Biplot analysis distinguished genotypes with wide and specific adaptation to environments with high and low genotype discrimination ability. There was two groups of sits, first one included the locations of Hama, Raqqa, Homs, Ghab, and Kameshli, second group included Jellin, Kefer Sandel, Yahmoul, Izraa, Tel Hadya and Harran. Der Elzour and Tel Ter, each one has different effect on the genotypes. The sites Jellin, Izraa, AlGhab were found as optimum locations for testing the genotypes, in addition a group of genotypes surpassed in productivity with genetic stability have been distinguished like Bohouth6 and Douma48114 Results showed the possibility of improvement the selection of bread wheat genotypes by applying AMMI model and GGE Biplot methodology in multi- Environment trails.
