Brief Project Summary:

Phytophthora sojae is a variable pathogen with over 55 races reported. Surveys conducted over 10 years ago found 6 races and 6 additional pathotypes in soybean fields in Arkansas. Resistance is conferred by a number of race specific RPS genes and non-specific resistance may also be present. The numerous resistance genes for Phytophthora root and stem rot and highly variable pathogen make screening for resistance to current races of the pathogen critical.

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.
