Conventional sunflower oil is regarded as a healthy oil by consumers around the world. Its main characteristics are a fatty acid profile rich in polyunsaturated linoleic acid, a moderate to high content of alpha-tocopherol, with high vitamin E activity, and a moderate to high content of phytosterols, which play an important role in reducing blood cholesterol and subsequently the risk of coronary heart disease. Notwithstanding these properties, sunflower breeders have been extraordinarily successful in developing new traits that either confer improved nutritional and technological properties to the oil for conventional uses or have opened up new applications for sunflower oil. Most of the genetic modifications of sunflower oil quality have affected the fatty acid and tocopherols profiles. New traits such as mid and high oleic acid content, both low saturated and high saturated fatty acid content, and different combinations of increased levels of beta-, gamma-, and delta-tocopherol have been developed. Some of them such as mid and high oleic acid content are playing an important role in the market, particularly in the US, where the industry has completely shifted to mid oleic acid sunflower oil. Others such as the combination of high stearic acid and high oleic acid, particularly well suited for the industry of margarines and spreads, and the combination of low saturate and mid or high oleic acid, with enhanced nutritional properties, are close to the commercial level. Germplasm with enhanced vitamin E (alpha-tocopherol) content has recently being developed and breeding research on phytosterols, just started, will probably throw a new set of traits in coming years. Despite most of the novel oil quality traits are qualitatively inherited, the integration of several traits in a breeding program requires strong support of molecular tools. There have been important advances in recent years in mapping and tagging genes underlying modified oil quality traits as well as identifying their role in the biosynthetic pathway through candidate gene approaches. However, a deeper understanding of the genetic and molecular bases of these traits is required, particularly in relation to the generalized presence of modifying genes affecting their expression.
