Final Project Results

We have seed from 326 recombinant inbred lines from Dwight x LG11-3187 and 350 recombinant inbred lines from Dwight x LG11-12313. In our previous yield testing LG11-3187 (F6 Dwight (4) x PI 441001) yielded 7.6 bu/a acre more than Dwight and was 6 days later in maturity than Dwight. LG11-12313 (F3 Dwight (5) x PI 441001) yielded 3.6 bu/a more than Dwight and was 1 day later in maturity. These yield mapping populations are ready for yield testing in 2016 and the results from that research will indicate the genetic introgressions from G. tomentella to soybean that has caused these very large yield increases.

We completed the third year of field data collection for the 800 recombinant inbred lines derived from crossing PI 483916 and PI 479752 with Williams 82. We have also completed the genotyping by sequencing for all 880 lines. Seed samples were harvested from the 2015 plots for classification and analysis.

The 416 experimental lines derived from wild soybean that we selected based on observations on over 1,700 plant rows in 2014 were evaluated in 2015 at two locations. We collected data on maturity, lodging, height and yield.
