Fifteen NS maize hybrids of FAO 300-700 maturity groups were evaluated in strip trials (plot size 1,120 square meter) at 30 locations in Serbia. In all locations including all production regions, the most yielding hybrid was NS 6030 with average yield of 10.9 t/ha. The additive Main Effects and Multiplicative Interaction (AMMI) and the sites regression (SREG) models were used to study basic structure of genotype x environment interactions and the possible existence of different mega-environments in Serbian maize growing regions in 2009. The results of the 15 hybrids x 10 locations for grain yield in maize showed by biplot technique indicate several specific location-hybrid deviations (the AMMI biplot), and possible existence of at least one mega-environment (the GGE biplot).
