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. Our material will be available to public and private breeding programs and seed producers with limited or no restrictions.

Project Objectives

1. Develop and release soybean varieties/germplasm with improved seed yield under dryland and irrigated production; seed composition (high oil and protein and oleic acid); resistance to: Cyst Nematode (SCN) and Sudden Death Syndrome (SDS).
2. Incorporate transgenic events into elite breeding lines.
3. Characterize stress tolerance and improve selection efficiency in soybean.
4. Characterize the virulence diversity in Kansas populations of soybean cyst nematode.

Project Deliverables

Progress of Work

The 2014 field crosses were harvested and all non-GMO progeny produced from these crosses have been sent to our winter nursery for generation advance. We continue the conversion and increase of one high yielding elite conventional line into a RR1 cultivar. We completed evaluations of over 2000 experimental K-lines and another 350 experimental lines from other states in over 10,000 replicated yield trials. Productivity and precision of the 2014 trials was above average. Our most advanced material performed well in the Uniform Testing program in 2014 and will be entered into additional tests in 2015. One hundred nineteen entries from the Kansas Soybean Variety Performance Test (KSVPT) were evaluated in replicated greenhouse trials for their reaction to two SCN populations that vary in virulence to the common resistance source PI 88788. Most entries (~60%) were moderately resistant, with fewer than 5% of entries displaying a high level of resistance. Field evaluations from 2011 through 2014 continue to characterize the relationships between spectral reflectance, seed yield, drought stress and other physiological traits, and develop molecular markers associated with important reflectance measurements. In an effort to apply remote sensing to breeding for drought and heat stress, we collected 100,000 spectral and canopy temperature (CT) observations on 1400 genotypes grown at 8 locations in 6000 plots in 2014.
