Abstract
Sunflower oil is a major important vegetable oil because it is widely used in human nutrition and in many industrial
productions depends on fatty acid composition. Field studies were conducted during in two years on the same soil to
investigate changes of climate induced oil fatty acid composition of a traditional sunflower, and to obtain correlations among
oil fatty acids. Seed oil content and twelve fatty acid percentages of sunflower oil were analyzed. Variations for years were
significant for seed oil content and palmitic acid (C16:0), oleic (C18:1), linoleic (C18:2), linolenic (C18:3), miristic (C14:0)
and eicosenoic acids (C20:1). Higher temperatures during seed development in 2010 resulted with 68.38 % increasing in
oleic content of the traditional sunflower hybrid. The highest negative correlations (r= -0.99) were noted between oleic and
linoleic acids.
