摘要：
The physical and chemical characteristics of five Syrian durum wheat cultivars grown under varying environmental conditions were investigated. Two cultivars were grown under irrigated conditions whilst two were grown under rainfed conditions in five different locations. A known cultivar (Sham-1) was grown alongside the samples in all locations as a control. Test weight, 1000-kernel weight, the degree of vitreousness, protein content, starch content, amylose content and starch pasting properties were determined for the samples. The effect of the environmental factors and their interaction (site x irrigation) showed that the irrigation factor was more responsible for physical quality variations than the site factor (for instance, site variation of the irrigated conditions was responsible for 61% of the total quality variation and 34% of total quality variations in the rainfed conditions). Starch composition was influenced more by site variations than irrigation, whereas cultivar factor mainly influenced starch quantity, chemical composition and pasting properties (for instance, variations were mostly affected by cultivar (63%) more than site (15%) in the irrigated lands). The interaction of cultivar and site demonstrated significant effects on the degree of vitreousness, amylose content and starch pasting properties.
