Abstract

This paper presents the results of 17 new OS-hybrid combinations of sunflower during three years (2009-2011) on two locations (Nova Gradiška and Osijek) aiming to determine the variability of oil content and fatty acid composition of the oil in different environments. There were statistically significant differences in oil content and fatty acid composition between years, locations and hybrids. The average oil content was 48.74%, the content of palmitic acid (C16:0) 5.626%, stearic (C18:0) 3.682%, oleic (C18:1), 24.741% and linoleic (C18:2) 64.447%. On both locations, the highest oil content was in 2011 (50.97%), oleic acid (27.379%) in 2009, and in 2010 the highest content of linoleic acid (66.153%). Statistically significant higher oil content, palmitic and linoleic acids were achieved on Nova Gradiška location. Statistically significant higher content of oleic acid (25.820%) was achieved on Osijek location. Palmitic, stearic, and linoleic acids were in statistically high significant medium strong to strong positive correlation with oil content, and oleic acid in a strong negative correlation (-0.660**). The ratio of oleic and linoleic acid was statistically significant in high negative correlation (-0.974**).
