 DES MOINES, Iowa , Jan. 10 /PRNewswire/ -- Pioneer Hi-Bred International (NASDAQ-NMS: PHBY) has been issued a patent for a sunflower with a maternally-inherited trait that reduces the level of saturated fatty acid in sunflower oil. This discovery allows plant breeders to reduce saturated fatty acids in any sunflower hybrid, including those already rich in unsaturated fats, thus further lowering the saturated fats in sunflower oil to produce healthier vegetable oils.
 Steve Shein, Sunflower Research Director for Pioneer stated, "Sunflower oil typically has more than 10 percent saturated fatty acids. New hybrids made with the low-sat trait may contain less than 6 percent total saturated fatty acids. This makes sunflower oil competitive with other healthy oils such as canola oil."
 The four primary fatty acids in sunflower oil are palmitic, stearic, oleic, and linoleic. Palmitic and stearic belong to the saturated-fat family. Reducing their levels decreases the amount of saturated-fat in the end product.
 The patented trait in the low-sat sunflower works to reduce the level of stearic acid in the final product, sunflower oil. Plant breeders at Pioneer have successfully reduced this level of stearic acid in the oils to less than 0.6 percent, with the additional result, of increasing the levels of unsaturated fatty acids, such as oleic acid. In fact, several Pioneer sunflower hybrids have been produced with oleic acid content well over ninety percent. Even in standard lines incorporating the trait, the linoleic acid content in the oil has been boosted to over 75 percent as the stearic acid levels have been reduced.
 Pioneer has grown hybrids with the low-sat trait on small acreages to determine the oil quality that can be expected from farm level productions. A limited quantity of oil has been produced for evaluation by Pioneer's Specialty Plant Products Division and is available for product testing by contacting Dr. Nick Frey, Oils Product Development Manager for Pioneer, tel. 515-254-2737, fax. 515-254-2744.
 The patent is part of Pioneer's overall plan to increase the value of crops for farmers by addressing the needs of the food and plant- derived chemical processing industries. Pioneer believes that the patented low-sat trait is important to the entire sunflower industry and is interested in developing business relationships that realize its potential. Inquiries about Pioneer's patent for low-sat sunflower should be directed to Dr. Tom Heaton, Sunflower Business Director for Pioneer, tel. 916-666-1084, fax. 916-666-1737.
