In order to evaluate the effect of heat stress on Sugars of commercial wheat cultivars, an experiment was conducted during 2017-2018 in a randomized complete block design with three replications under two conditions, normal sowing (6 November) and late sowing (5 January) on 6 wheat genotypes in the experimental field of Shahid Chamran University of Ahvaz. The metabolic traits including glucose, fructose, sucrose, raffinose, stachyose were evaluated. Also, cultivar in sowing date interaction showed significant difference for glucose, fructose, sucrose, raffinose and stachyose (P≤0.05). Mehregan, pishtaz and Kauz, show stability of metabolic
