摘要：
In order to investigate the effects of the waterlogging periods on wheat grain yield and yield components among cultivars, a research was conducted in center of agricultural research in Ahwaz, using a treatment method of split-plot based on randomized complete block design (RCBD), with three replications. This research was based on two factors such as wheat varieties (Chamran, Virinak, S-80-18, S-78-11) and waterlogging periods (WL) (0, 10 and 20 days). The results showed that in terms of kernel yield and yield components, there were significant differences between cultivars and different periods of WL. With affected by WL, S-80-18 had maximum kernel yield (3.15 t/ha) than other cultivars. The kernel yield was decreased by WL upto 1.78% per day. Among wheat yield components, number of spikes per acre indicated maximum damage from WL.
