Two-year multi-environment trial which included 26 locations evenly distributed in sunflower growing area in Serbia, was used as a source of data, for the estimation of adaptability for 25 NS commercial sunflower hybrids, based on grain yield and oil yield. GGE biplot, graphically displays genotype main effect and genotype-by-environment interaction effect, simplifying visual evaluation of genotypes and environments. ANOVA showed the most important influence of location factor on the magnificence of grain yield and oil yield, which legitimate the use of the SREG model in the analysis of the environment-centered data. Biplot polygon view analyses showed different mega-environments in sunflower growing area in Serbia, generally and specifically adaptable hybrids, hybrids average performance and stability, discriminating and representative test locations. Rimski Sancevi and Kikinda formed mega-environment based on the analyses of oil yield through single years. Combined analysis for grain yield in both years showed that Aleksa Santic, Backa Topola, Kula Vitovnica and Pozarevac formed mega-environment. Combined analysis for oil yield in both years showed that Kragujevac, Kula Vitovnica and Pozarevac formed mega-environment.
