For this purpose, ten bread wheat genotypes were grown in randomized complete block design with 3 replications under rainfall conditions in the experimental field of GAP International Agricultural Research and Training Center during the 2012-2013 growing season. The most high yielding varieties in this study, Pehlivan, Kate A-1, Cemre and Anapo, were observed as standing out in terms of flag leaf chlorophyll content (SPAD value), flag leaf ash ratio, leaf area index and grain filling period . The correlation analyses of the study showed positive and significant correlations between chlorophyll content of flag leaf at heading stage with chlorophyll content at flowering stage, between chlorophyll content of flag leaf at flowering and heading stages with chlorophyll content of flag leaf at milk stage and between grain filling rate with leaf area index, In addition, positive and significant correlations were identified between flag leaf ash ratio and NDVI reading prior to heading time with grain yield CR - Araus, J.L., Amaro, T., Casadesus, J., Asbati, A. & Nachit, M.M. 1998.
