Brief Project Summary:

The project enables NDSU to continue developing glyphosate-resistant soybean cultivars. There are glyphosate-resistant experimental lines in the NDSU breeding program being tested in a range of maturities from a 1.0 to a 00.7. New experimental lines are developed each year. This project will significantly reduce seed costs to soybean growers. Cultivars developed at NDSU are not patented. The cost savings for growers that purchase glyphosate-resistant cultivars developed by NDSU will occur the second and subsequent years after the initial purchase of the seed. The seed of new experimental lines will be increased in Chile each winter to speed the development and release.

Key Benefactors:

Research Conducted
Glyphosate-resistant experimental lines have been developed by the NDSU Soybean Breeding Project. Crosses were initiated in the summer of 2010 and new crosses have been initiated in every subsequent year. As part of the continuing process of developing new lines, 1310 new experimental glyphosate-resistant lines were evaluated for yield in replicated plots in 2018. Seed of one advanced experimental line, ND15-22873GT, was increased in Chile, S.A. during the 2018-2019 winter season. ND15-22873GT has a 0.7 relative maturity, is tolerant to iron-deficiency chlorosis and has similar yield to commercial check varieties. Each year there is the potential of releasing high-yielding new glyphosate-resistant cultivars that were developed by NDSU.
Why the research is important to ND soybean growers
Growers would like to purchase glyphosate-resistant soybean varieties and be able to save their own seed for planting the next year. This would reduce their input costs and could be especially beneficial for fields that have limited yield potential. These varieties need to be high-yielding, lodging-resistant, tolerant to iron-deficiency chlorosis (IDC), and have good disease and pest resistance. Soybean varieties are protected by a patent on the glyphosate-resistant gene (construct) and often protected by a second patent on the variety. Monsanto has provided a website to explain these issues (http://www.soybeans.com/patent.aspx). The purpose of this research is to provide superior glyphosate-resistant varieties that have been developed by North Dakota State University (NDSU). At this time, two glyphosate-resistant soybean varieties that have been developed by NDSU are available to growers.

Final findings of the research
ND17009GT is a 00.9 maturity and ND18008GT is a 00.8 maturity variety and both are glyphosate-resistant. ND15-22873GT is an experimental line that was pre-released with a 0.7 maturity and is glyphosate-resistant. ND15-22873GT has been approved for pre-release and seed is being increased during the 2019 growing season. The decision to release ND15-22873GT will be made in January, 2020.

Benefits/Recommendations to North Dakota soybean farmers and industry
The benefit to the North Dakota soybean industry is reduced cost of soybean seed for varieties that are glyphosate-resistant. Farmers can save their own seed of ND17009GT, but cannot save their own seed of ND18008GT. When soybean growers can save their own seed of glyphosate-resistant soybean varieties, this reduces their input costs. They can then plant this seed without paying a technology fee.

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.
