The objective of this study was to determine relationships between stomatal conductance and yield components. Field trials were conducted at Field Crops Department Research Area, Agricultural Faculty, University of Cukurova during the 2000-2001 growing season in a completely randomized blocks design with three replications. The measurements of stomatal conductance (g(s)) were made at three stages (early milk, late milk and early dough maturity). Stomatal conductance showed statistically differences among genotypes. Genotypes showed differences for all agronomical traits assessed. Stomatal conductance had positive correlations with grain yield, grain numbers per spike, spike yield, and spike length at early stage. Results are discussed in terms of the possibilities of g(s) to be a criteria in wheat breeding at Cukurova Region.
