4d Progress report. This report serves to document research conducted under a specific cooperative agreement between ARS and the University of Maryland. Additional details of research can be found in the report for the parent project 6645-21000-025-00D, Fundamental mechanisms for genetic alteration of soybean quality and productivity. The objective was to develop soybean varieties with improved oil quality that would perform well in Maryland and similar production environments. Maryland soybean breeding lines with low-saturate oil and/or low-linolenic acid oil, were grown in the 2004 national Quality Traits Tests. Low linolenic acid will give the oil more stability without oil hydrogenation. The lines had yields that were between 63 and 91% of the conventional check varieties. Lines with just the low linolenic acid trait seem to yield better than lines that have just the low saturate trait or that have a combination of the two traits. The first Maryland lines that
have all three of the oil traits- low saturates, mid-oleic acid, and/or low linolenic acid were in multi- location yield tests in 2004. Some of these were selected for further yield testing. Because of the large amount of soybean oil consumed in the USA, lowering intrinsic saturate levels in the oil would significantly decrease the USA consumption of saturated fat (a contributor to coronary heart disease) without dietary change. Mid-oleic low-linolenic soybean oil would provide consumers oil with better flavor in prolonged usage.

4. What were the most significant accomplishments this past year? This report serves to document research conducted under a specific cooperative agreement between ARS and the Department of Natural Science Resource and Landscape Architecture, University of Maryland. Additional details of research can be found in the report for the parent project 6645-21000-025-00D, Fundamental mechanisms for genetic alteration of soybean quality and productivity. Development of mid-oleic, low-linolenic and/or low-saturate soybeans provides food industry and consumers with a potential source of higher- quality, more healthful vegetable oil. Six potential soybean varieties with low-saturate and/or low-linolenic acid seed oil were developed for production in Maryland and similar environments. These soybeans were entered in the 2004 national quality-traits test and are currently being evaluated. Because of the large amount of soybean oil consumed in the US, lowering intrinsic saturate
levels in the oil would significantly decrease the US consumption of saturated fat (a contributor to coronary heart disease) without dietary change. Mid-oleic low-linolenic soybean oil would provide consumers an oil with better flavor in prolonged usage.
