Information And Results
Project Deliverables

- We will know if the individual gene confers resistance to all three SCN isolates.
- We will be able to develop six homozygous lines for six combinations of three PSS30 and two GmDS1 gene fusions with three and two promoters, respectively (Table 1).
- We will learn if the two genes together can improve SCN and SDS resistance significantly among the homozygous transgenic Williams 82 lines as compared to their respective parental lines containing single genes (either PSS30 or GmDS1).
- A combination of PSS30 and GmDS1 genes is expected to be used in commercial soybean lines carrying rgh1-b or other SCN resistance genes as well as SDS resistance genes.

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.
