Project Summary

This program will develop new soybean germplasm with superior traits or unique combinations of traits. This will help increase the competitiveness of U.S. soybean producers. Superior genetics represent the foundation for increasing yield and protecting yield from pests and pathogens. We will focus on the development of Kansas adapted germplasm in conventional (non-gmo) backgrounds to minimize intellectual property rights issues. Some conventional lines will be developed with STS herbicide resistance. The genetic material will be available to public and private breeding programs and seed producers with limited or no restrictions.

During the summer of 2013, experimental lines in maturity groups III-V will be tested at six breeding nurseries located throughout Kansas. They established a Soybean Sudden Death Syndrome/Soybean Cyst Nematode (SCN) site at two northeast Kansas locations and a "drought" location in central Kansas. These sites will continue to be used in cooperative studies with the University of Missouri, the University of Georgia and the USDA at Stoneville, MS to screen for drought resistance. Plans are underway to develop the technology for high-throughput phenotyping for seed yield and drought tolerance in field trials. They are preparing to collect remote sensing data on the soybean breeding plots using both ground and aerial equipment this season.

Project Objectives

1.Develop and release soybean varieties/germplasm with improved genetic traits.
2. Incorporate transgenic events into elite breeding lines.
3. Refine methods to determine the genetics of Dectes stem bore resistance in soybean PI 165673.
4. Characterize stress tolerance and improve selection efficiency in soybean.
5. Characterize the virulence diversity in Kansas populations of soybean cyst nematode.
6. Develop best management practices for fungal disease control in soybean, with special consideration for seedling disease, season-long charcoal rot control, early and mid-season leaf disease control, and late foliar, pod, and stem disease control.

Progress of Work

Final Project Results

Information on resistance levels of commercial soybean cultivars to Kansas populations of SCN provides growers with info necessary to increase profitability of soybean production in SCN-infested environments. Characterization of SCN virulence patterns and results of research on resistance-based management practices and durability of resistance sources is being used to improve management recommendations. Knowledge of the prevalence of SCN and HG Types in Kansas is guiding soybean breeding efforts and providing soybean producers with information vital to variety selection. Current information on the efficacy of nematode control products is disseminated at grower meetings and field days to improve decision-making knowledge. Effects of high temperature stress on soybean were published at scientific conferences and published in peer reviewed publications.
