Variability of some physico-chemical characteristics of wheat cultivars grown under arid and semiarid Mediterranean conditions

Variability in some physicochemical characteristics of 22 durum wheat (Trit icum turgidum L. var. durum) cultivars was investigated. The experiments we re carried out under rainfed conditions at an arid (Jordan University of Sc ience and Technology [JUST]) and a semiarid (Maru) location in northern Jor dan. Statistical analysis revealed significant differences among the cultiv ars for each characteristic. Location X cultivar interaction was significan t for all characteristics except for SDS-SED. Results showed that the semia rid growing location (Maru) proved to be favorable for production of durum wheat higher in gluten, amylose, amylopectin, and milling yield.
