Interaction between hybrids and locations for oil content and oil yield in sunflower

Abstract

The aim of this study was to assess the effects of hybrids and locations, as their interaction, on oil content and oil yield of sunflower in a network of small-plot trials in Vojvodina and central Serbia in 2007. 20 sunflower hybrids and 16 locations were included in the experiment. Hybrids Somborac, Bačvanin, Baća, Branko, Šumadinac and NS-H-111, were stable for oil content. Hybrid Somborac was the most stable and had also highest mean value for oil content. The most stable oil content was found in hybrids realized at locations L6 (Sombor), L8 (Kikinda), L12 (Neštin), L2 (Kula), and in central Serbia L15 (Negotin). Šumadinac, with highest mean value for oil yield was the most stable. The hybrids Somborac, Branko and Oliva with mean values over average value for oil yield showed also high stability. Locations L8 (Kula) and L1 (Rimski Šančevi) showed lowest interaction for oil yield. Graphical presentation of AMMI1 in the form of biplot could facilitate the choice of stable hybrids and locations for desired characters in sunflower. .

Cilj rada je bio da se ispita interakcija između hibrida i lokaliteta za sadržaj i prinos ulja suncokreta u mikroogledima izvedenim u toku 2007. godine na teritoriji Vojvodine i centralne Srbije. U istraživanje je bilo uključeno 20 hibrida i 16 lokaliteta. Interakcija je prikazana pomoću AMMI1 biplota. Hibridi Somborac, Bačvanin, Baća, Branko, Šumadinac i NS-H-111, pokazali su stabilno ponašanje u pogledu sadržaja ulja u semenu. Hibrid Somborac bio je najstabilniji, a imao je i najveću prosečnu vrednost za sadržaj ulja. Najstabilniji sadržaj ulja hibridi su ostvarili na lokalitetima L6 (Sombor), L8 (Kikinda), L12 (Neštin), L2 (Kula), a u centralnoj Srbiji L15 (Negotin). Šumadinac, sa najvećom prosečnom vrednošću za prinos ulja, bio je i najstabilniji. Visoku stabilnost pokazali su i hibridi Somborac, Branko i Oliva, koji su imali veću srednju vrednost u odnosu na opšti prosek. Lokaliteti L8 (Kula) i L1 (Rimski Šančevi) su bili sa najmanjom interakcijom za prinos ulja. Grafički prikaz (AMMI1 biplot) omogućava izbor stabilnih hibrida i lokaliteta za poželjne osobine suncokreta. .
