The aim of this study was to evaluate NS sunflower hybrids on the basis of the results of seed yield, seed oil content and oil yield obtained in a network of small-plot trials in Serbia in 2011. The trial included 9 hybrids and 14 locations. Seed yield, seed oil content and oil yield were significantly different in small-plot trials in the investigated regions of Serbia. The highest average seed yield was produced by Sremac (3.67 t ha-1), Velja (3.62 t ha-1), Duško (3.56 t ha-1) and Novosađanin (3.55 t ha-1). On the location Rimski šančevi the seed yield (4.48 t ha-1) was significantly highest. Average oil content for hybrids grown in 14 locations was 47.25%. Hybrids Baća (50.26%), NS-H-111 (48.91%), Bačvanin (48.70%) and Novosađanin (47.83%) showed the highest average seed oil content. The highest average oil yield was produced by Baća (1.71 t ha-1), Novosađanin (1.70), Velja (1.67 t ha-1), Sremac (1.63 t ha-1) and NS-H-111 (1.63 t ha-1). Locations with the highest oil yield were Rimski šančevi (2.03 t ha-1) and Sombor (1.96 t ha-1). In the four-year trials in Vojvodina, the average seed yield of 9 hybrids was 3.35 t ha-1. Seed yield over general mean was reached by three hybrids (Duško, Sremac and Velja). The highest seed yield was reached by hybrid Duško (3.56 t ha-1). AMMI1 biplot showed that most stable and with high seed and oil yield were the hybrids Duško, Sremac and Baća, and for oil content Baća, Bačvanin and NS-H-111.
