Interpretive Summary: In recent years American consumers have become concerned with reducing the saturated fat content of their diet. Studies have indicated that high levels of saturated fat consumption are correlated with increased risk of coronary heart disease. The sunflower Research Unit in Fargo, ND, has therefore undertaken a project to reduce the percent of saturated fatty acids in sunflower oil. Two sunflower lines, RP13 and RP35, with reduced saturated fatty acids were developed from selections of a cross between HA 89 and PI 250542, a sunflower line identified from the National Plant Germplasm Collection as having variability in palmitic acid composition. During the past three years six additional cycles of selections were made, and the resulting compositions were decreased even further than reported in 1998. The saturated fatty acid content of RP13 was 7.61%, and that of RP35 was 7.70%, compared to a range of 10.49% to 14.51% for several control lines.
