Abstract: 

Intermediate-late and early tropical highland maize hybrids, were evaluated in two seperate experiments. Each experiment included 11 hybrids and one adapted commercial hybrids, KSC 647(medium maturity), using randomized complete block design with 3 replications and carried out in 4 locations of Iran (Karaj, Gorgan, Darab and Dezful) in 2002 cropping season. Results indicated that these type of hybrids performed better adaptation for synchronized pollen shedding and silk emergence in Darab and Dezful. These germplasm were not useful for Gorgan and Karaj, where they produced low yield due mainly to high anthesis-silking interval (ASI). Although, these hybrids are not suitable to be used directly, it would possible to use them as a knew genetic resources, especially for incorporating tolerance to early season low temperature, as they are originated from highlands.
