Hind Nouar, Hamenna Bouzerzour, LeilaHaddad, Abdelkader Menad, Tahar Hazmoune and Hocine Zerargui; Genotype xEnvironment Interaction Assessment in Durum Wheat (Triticum durumDesf) using AMMI and GGE Models ABSTRACT Development of varieties with high yield potential coupled with wide adaptability is an important plant breedingobjective. The presence of genotype by environment interaction plays a crucial role in determining theperformance of genetic materials, tested at different locations and in different years. This study was undertaken toassess yield performance, stability and adaptability of twelve durum wheat genotypes evaluated over five environments. There was highly significant genotype-environment interaction. The use of the additive model as well as the joint regression proved to be inefficient in the interpretation of results compared to AMMI analysis of variance which explained90.80% of the sum of square of the interaction. This analysis indicated that cultivar Waha exhibited a wide adaptation across all test-sites, while the GGE biplot analysis indicated that the five test-locations represented 3sub-regions where Mrb3, Boussalem and Badre were the winners.
