Environmental stability in hybrid maize using the AMMI model in the ecuadorian coast

The objective of this study was to evaluate the adaptability, and yield stability of seed in 27 varieties of hybrid maize using the AMMI (additive main-effects and multiplicative interaction) model. The trials were performed in three types of environments on the Ecua- dorian coastline during the dry season of 2012. We conducted a combined analysis of variance and an analysis of consistency of the areas. Finally, we conducted the additive main-effects and multiplicative interaction analysis of the yield variable. The environment, hybrid and the hybrid-environment interaction accounted for 13.74, 43.78 and 15.50% of total sum of squares, respectively. The main component of the AMMI model had a significant (P<0,001) value, accounting for 82.11% of the sum of squares of the interaction. The selected triple hybrids H11 and H15 showed high yield and stability for all three environments. The most efficient environment for dis- crimination of hybrids was the Santa Ana area. The AMMI model proved useful for identifying hybrid maize varieties that were highly productive and stable.
