Brief Project Summary:

Soybean root and stem rot caused by the soil-borne oomycete pathogen Phytophthora sojae is one of the most destructive diseases of soybean. In the past decades, a few genes/alleles conferring resistance to Phytophthora sojae (designated as Rps genes) were used to develop resistance soybean cultivars - an economical and effective approach to protecting soybean from this disease. However, the resistance contributed by individual Rps gene is non-durable and usually effective only for approximately 10 years due to the rapid variation of P. sojae races. A promising strategy for breeding more durable resistance is to stack multiple, broad spectrum, resistance genes in single cultivars.

Information And Results
Final Project Results

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.
