Title: Innovations by Walter R. Fehr: Advancements in Soybean Genetic Determinants.

Introduction: Walter R. Fehr, located in Ames, Iowa, is a prominent inventor and researcher known for his significant contributions to the field of agriculture, particularly in soybean genetics. With an impressive portfolio of 25 patents, Fehr has been at the forefront of developing novel genetic determinants that enhance the nutritional profile and utility of soybeans.

Latest Patents: His latest innovations focus on two specific areas:

1. **Reduced Linolenic Acid Production in Soybeans**: This patent describes soybeans (Glycine max L. Merr.) that possess a genetic determinant allowing for reduced production of linolenic acid in their vegetable oil. The critical genetic determinant, the homozygous recessive fan3fan3 gene pair, can be created through mutagenesis and is transferable to other soybean lines. The resulting soybean plants express less than 1.3 percent, with a preferred maximum of 1.1 percent, linolenic acid based on the total fatty acid content. This innovation enables the production of vegetable oil suitable for frying applications without the need for hydrogenation.

2. **Elevated Palmitic Acid Production in Soybeans**: In another remarkable achievement, Fehr's patent pertains to enhancing palmitic acid production in soybeans through the homogeneous recessive fap5fap5 gene pair. Once this genetic determinant is established, it can be transferred efficiently across cultivars. The enhanced palmitic acid production can reach levels exceeding 30 to approximately 37 percent by weight based on total fatty acid content. This vegetable oil is particularly beneficial for margarine production without requiring hydrogenation.

Career Highlights: Walter R. Fehr has dedicated much of his career to advancing agricultural sciences, particularly through innovation in soybean genetics. Through his work at Iowa State University Research Foundation, Inc., he has published numerous research papers and has significantly influenced the agricultural industry with his patented technologies.

Collaborations: Throughout his career, Fehr has collaborated with notable individuals such as Earl G. Hammond. These partnerships have fostered innovative research and development, further enhancing the reach and application of his inventions.

Conclusion: Walter R. Fehr's contributions to soybean genetics are invaluable, positioning him as a leading inventor in agricultural innovation. His work not only advances our understanding of genetic determinants in crops but also offers practical solutions for enhancing food products through improved oil profiles in soybeans. His ongoing research and collaboration with other experts continue to pave the way for future advancements.
