Abstract

This study was carried out to evaluate drought tolerance of 12 SWEET CORN hybrids in 2006 at Seed and Plant Improvement Institute in Karaj. Treatments were arranged as a split-plot experiment in randomized complete blocks design with three replications. Main plots included three irrigation levels (Irrigation after 75, 100 and 125 mm evaporation from class A evaporation pan as normal, mild and high stress conditions respectively) and 12 hybrids (KSC403su, Chase, Esquire, Rival, Reveille, Diva, Shimmer, Shaker, PS107, Golda, Royalty and Rana) were assign as subplots. Irrigation regimes and hybrid effects for all of the traits and their interaction effect for 1000 kernels weight and grain YIELD were significant (p£0.01). Increasing DROUGHT STRESS from normal irrigation to mild stress and high stress conditions were resulted in decreasing all the traits significantly. The maximum and minimum grain YIELDs were obtained from PS107 and Rival hybrids (8.35 and 4.86 t/ha respectively). This experiment revealed that delay in irrigation more than 75 mm evaporation decreases the YIELD. It recommended that hybrid PS107 is cultivated where there is enough water for irrigation. In low available irrigation water using of hybrids Rival, Diva and Golda is not recommended.
