DuPont identifies molecular markers that improve soy productivity

DuPont business Pioneer Hi-Bred announced that it has identified and incorporated new proprietary molecular markers into its soy research programme.


The new markers, which are non-transgenic and are not subject to additional regulatory approvals, enhance the company's ability to bring to market soy resistant to three common destructive soy pests -- Asian Soybean Rust, soy aphids and frogeye leaf spot.


If left untreated, Asian Soybean Rust, soy aphids and frogeye leaf spot can cause significant damage and yield loss to soy.


The molecular markers will help to boost soy yields by 40 percent within the next 10 years, according to William S. Niebur, vice president of 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," Niebur said.


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.
