Four wheat cultivars and their F-1 hybrids, at full diallel design, were sown timely and late to represent non-stress and stress conditions. The objectives of this study were to (1) investigate gas exchange (A(n),g(s), C-i, A(n)/C-i), canopy temperature depression (CTD), chlorophyll content measured by SPAD-502 chlorophyll meter (SPAD, soil plant analysis development) and certain agronomic traits, (2) to determine the relationships among all traits, and (3) to obtain genetic information on physiological traits via diallel analysis. Gas exchange at the medium milk development stage and SPAD measurements at the heading and late milk development stages were made on flag leaf. CTD was measured at medium milk development at three different times of day: late morning, noon and early afternoon.
