Final Report

Brief Project Summary:

One of the most destructive pathogens of soybean in the US, and especially Ohio, is Phytophthora sojae, a soil-borne oomycete that causes seed, root and stem rot. The proposed research aims to identify soybean genes involved in partial (quantitative) resistance to P. sojae. Unlike other types of resistance, partial resistance is expected to be durable, to be effective against all races of P. sojae, and to prevent rapid pathogen evolution. The ideal package of resistance to P. sojae includes high levels of partial resistance in combination genes for race-specific resistance to P. sojae (Rps genes); however, selection for this combination is difficult. Breeding for resistance to P. sojae would...

Information And Results

Project Deliverables

Provide genes and genetic regions for Phytophthora resistance that can be immediately utilized by public and industry breeders.
Provide a model for similar studies that may be conducted for resistance to other pathogens of significance to soybean in Ohio.

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.
