2008 Annual Report
Objective: Develop sub 3% linolenic acid soybean lines in three different maturity backgrounds.
The report details progress on a project initiated in March 2008. The project is intended to determine the quality of soybean lines developed with unique genetics to produce low linolenic acid in the seed oil, an industry desired trait. Since the linolenic acid component is unstable, it was historically removed by chemical hydrogenation, which introduced trans fats to the oil. By classical genetics methods, the linolenic acid component can be reduced to below 3% of the oil fraction and therefore eliminate the need for chemical hydrogenation and create trans-fat free soybean oil. This project will develop sub 3% linolenic acid soybean lines that can be used in breeding programs as a basis for developing elite varieties in many maturity groups encompassing the majority of the soybean growing regions in the United States. The project is based on making new combinations of different genes that produce the low linolenic acid phenotype. The donor and acceptor soybean lines have been chosen for the project and are ready to be cross-hybridized to initiate the research. Molecular marker assays have been developed which allow the selection of the desired progeny plants.
