Evaluation of NS sunflower hybrids in small-plot trials via hybrid × location interaction

Abstract

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.

Cilj rada bio je da se ocene NS hibridi suncokreta na osnovu rezultata koje su ostvarili za prinos semena, sadržaja ulja u semenu i prinosa ulja u mreži mikro-ogleda u Srbiji tokom 2011. godine. Ispitivano je 9 hibrida na 14 lokaliteta. Prinos semena, sadržaj ulja u semenu i prinos ulja su se značajno razlikovali u mreži mikro-ogleda u ispitivanim regionima Srbije. Najveći prosečan prinos semena ostvarili su hibridi Sremac (3,67 t ha-1), Velja (3,62 t ha-1), Duško (3,56 t ha-1) i Novosađanin (3,55 t ha-1). Na lokalitetu Rimski šančevi postignut je značajno najveći prinos semena (4,48 t ha-1). Prosečan sadržaj ulja za 9 hibrida, gajenih na 14 lokaliteta iznosio je 47,25%. Najveći prosečan sadržaj ulja u semenu ostvarili su hibridi Baća (50,26%), NS-H-111 (48,91%), Bačvanin (48,70%) i Novosađanin (47,83%). Prosečan prinos ulja u Srbiji iznosio je 1,63 t ha-1. Najveći prosečan prinos ulja imali su hibridi Baća (1,71 t ha-1), Novosađanin (1,70 t ha-1), Velja (1,67 t ha-1), Sremac (1,63 t ha-1) i NS-H-111 (1,63 t ha-1). Lokaliteti sa najvećim prinosom ulja su bili Rimski šančevi (2,03 t ha-1) i Sombor (1,96 t ha-1). Na osnovu rezultata četvorogodišnjih ispitivanja u regionu Vojvodine, opšti prosek prinosa 9 hibrida iznosio je 3,35 t ha-1. Prinos semena iznad opšteg proseka postigli su hibridi Duško, Sremac i Velja, pri čemu je hibrid Duško imao najveći prinos (3,56 t ha-1). Kao najstabilniji hibridi za prinos semena i prinos ulja na ispitivanim lokalitetima, na osnovu AMMI1 biplota, pokazali su se Duško, Sremac i Baća, a za sadržaj ulja Baća, Bačvanin i NS-H-111.
