Brief Project Summary:

Phytophthora sojae continue to plague parts of the North Central region, primarily due to adaptions by this pathogen to the current resistance genes that are in today's cultivars. New sources of Rps genes have been identified, but their introgression into high yielding elite lines has been slow primarily due to the "wild" nature of the sources of resistance. Also, the levels of partial resistance have "eroded" over the past decade due to the introduction of novel traits. As a result where P. sojae is a problem, late season development of Phytophthora stem rot is becoming more common. Late season stand loss, contributes substantially more to yield loss, since plants can not compensate...

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.
