Brief Project Summary:

The occurrence of the Dectes (soybean stem borer), Dectes texanus, is increasing in much of Kansas, however, the reason for this expansion is not known. This continuing project is investigating factors that may be attributed to the availability of alternate hosts, winter survival and other environmental factors.

The research team was first to demonstrate that resistance to D. texanus damage is heritable and can be selected for individual soybean plants. The genes involved in resistance from soybean PI 165673 are being mapped using QTL (quantitative trait loci). DNA from all F2 derived - F3 plants are being used to identify molecular markers linked to the resistance genes.

Final Project Results

Results of experiments in 2011 and 2012 conducted by Lina Aguirre, a M.S. student, indicate that several genes control resistance in PI165673. For D. texanus, preliminary results suggest that adult colonization patterns vary between fields and through time.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
