Drought stress as the most important abiotic stress plays an important role in the yield reduction of crop plants worldwide. For improvement of complex traits such as yield possessing low heritability, indirect selection is applied using other traits viz morph-physiological traits. This study was conducted to evaluate the effect of water stress on the agronomic and morphological traits of 169 recombinant inbred lines (RILs) in wheat (Triticum aestivum L .), using two separate lattice design (drought and control) at Research Farm of Isfahan University of Technology in 2011-2012. Two moisture regimes of 70 and 130 mm evaporation from evaporation pan ltr" Key words: Recombinant Inbred Lines, Yield components, Drought stress, Grain yield,
