Molecular markers boost soybean productivityDuPont business Pioneer Hi-Bred today announced it has identified and incorporated new proprietary molecular markers into its soybean research program. The new markers help boost the yields of soybeans resistant to three common destructive soybean pests--Asian Soybean Rust, soybean aphids and frogeye leaf spot. "These molecular markers will help us boost soybean yields by 40 percent within the next 10 years," said William S. Niebur, vice president, DuPont Crop Genetics Research and Development. "These markers are part of our industry leading Accelerated Yield Technology (AYT) that harnesses the power of our germplasm collection, strong bioassays, computing power and molecular breeding tools to drive genetic gain at unprecedented rates." "The addition of these novel markers to our soybean product development approach will build and extend our number one brand position in soybeans," Niebur said. Pioneer soybean breeders are using these new technologies to bring better products to its customers as quickly as possible. The markers are non-transgenic and are not subject to additional regulatory approvals. Pioneer is seeking patent protection on resulting improved soybean varieties, as well as the tools and techniques used to develop them. Molecular markers act as genetic road signs, indicating where scientists should look on a segment of DNA for genes related to a specific trait. Once molecular markers are identified, researchers can use DNA analysis early in product development to screen for the presence of these specific traits. This ability to screen complements extensive trait-specific field testing, for complex traits, driving greater success in research programs.
