Production of considerable part of wheat is in rainfed conditions. Hence, identification and selection of suitable breeding methods and using of proper and applying selection criteria to introduce drought tolerant varieties are very important. Selection efficiency for a trait is related to its heritability and kind of involved genes actions. Additive gene effects have the important role in heritability of traits. Therefore, to evaluate inheritance of proline content in leaves, an experiment was conducted with 50 F2:3 lines with parents (total 52 lines) in randomized complete block design with three replications. Results of experiment showed that proline content in leaves has additive gene effects and relatively high narrow- sense heritability. Therefore, for this trait relatively high genetic gain from selection can be expected and recommended for breeding of wheat populations to drought tolerance.
