Abstract :This study aimed to evaluate the performance of some bread wheat varieties in different environments, and to reveal the relationships between some physiological parameters and yield and yield components. Three bread wheat varieties, insert ignore into journalissuearticles values(Namely, Basribey 95, Alibey, and Kaşifbey 95);, were used as plant materials. Field experiments were conducted during the 2009-2010 and 2010-2011 growing seasons in Aydın and Menemen locations. The experimental layout was a RCBD with three replications at each location and year. In the study, canopy temperature depression insert ignore into journalissuearticles values(CTD);, chlorophyll content insert ignore into journalissuearticles values(CC);, stomatal conductance insert ignore into journalissuearticles values(SC);, grain yield insert ignore into journalissuearticles values(GY);, plant height insert ignore into journalissuearticles values(PH);, spike number per square meter insert ignore into journalissuearticles values(S/m2);, thousand kernel weight insert ignore into journalissuearticles values(TKW);, test weight insert ignore into journalissuearticles values(TW);, grain number per spike insert ignore into journalissuearticles values(G/S);, single spike yield insert ignore into journalissuearticles values(SSY);, number of days to heading insert ignore into journalissuearticles values(DHE);, were examined. CTD in ZGS 65 had a decisive role in gaining high grain yield. Also, CC in ZGS 65 and ZGS 71 might be defined as an important physiological traits. On the other hand, the contribution of the SC parameter determined in ZGS 55, ZGS 65 and ZGS 71 to the yield depends on the environment. Those parameters could be selection criteria for high-yield wheat breeding due to positive and significant correlations with grain yield. And also SC and CC parameters might be used in yield estimation on wheat.
