This study was conducted to investigate the associations between physiological and agronomicaltraits of different bread wheat genotypes in dryland conditions. 20 genotypes (including 18 lines and 2 cultivars) were investigated in one experiment using randomized complete block design with four replicates in dryland conditions during 2006- 2007. Traits measurements were carried out at the anthesis and physiological ripening stages. In this experiment 16 agronomical traits and 10 physiological traits were measured. According to the results of canonical correlation analysis, it can be concluded that selection for agronomical traits including lower height and percentage of leaf dry matter as well as higher percentage of spike and stem dry matter, spike length, 1000- grain weight and yield would result in the selection of effective physiological traits such as, higher chlorophyll content index, leaf area, specific leaf dry weight, relative water content and photosynthetic water use efficiency and lower stomatal conductance under drland conditions.
