The environmental stresses are most common in Algeria. Drought, cold and hot weather are often present. These production constraints are abiotic, they are combined together more aggravating the loss in crop yields, especially durum. Indeed, a study was conducted under different agro-ecological conditions in the 2010/11 year. The approach adopted has been characterized by integration across experiment and pedoclimatic zoned. To do this, tests were conducted at the three zones and followed up from the installation the plant to harvest. The observations concern the effects of environmental constraints on yield and traits associated; with measurements, it is focused on morpho-phenological characteristics of the vegetation, soil moisture and physicochemical properties of the soil. A substantial variation in yield were observed between zones can be explained by the significance soil tillage, crop rotation the characteristics of each zone.

Results confirm particularly that correlations between yield and associated characters exist and that various genotypes respond differently with the environments. Improved genotypes and precocious ensure the best yield. The early stage of heading is a trait often sought in Mediterranean areas, since it allows them to avoid the terminal water deficit or deficiency. The study confirmed the existence of significant correlations entered yield and it is components of and that genotypes responded differently depending on the environment to which they are subjected.
