Sever coldness causes damage to the wheat and affect its growth and yield, thereby this experiment was conducted in controlled conditions to investigate freezing tolerance of 29 wheat genotypes. Acclimation treatments (in two levels: acclimation and non-acclimation) were considered in the main plot and combination of temperature (0, -4, -8, -12, -16 ◦C) and genotypes as sub plot. Survival percentage, dry weight and plant height were measured four weeks after freezing in the glasshouse. All these traits were affected significantly by freezing treatments (P
