Research Project: ENHANCING RESISTANCE TO ROOT ROT PATHOGENS OF SOYBEAN Project Number: 3602-21220-011-00
Project Type: Appropriated

Start Date: Jun 05, 2007
End Date: Apr 22, 2012

Objective 1: Identify predominant races of Phytophthora sojae and assess the effectiveness of soybean resistance genes for incorporation into improved germplasm. Objective 2: Determine variability in virulence patterns of new and established Phytophthora sojae races. Objective 3: Establish and maintain isolates of Phytophthora sojae races as a resource for soybean germplasm enhancement and race identification of new field isolates. Objective 4: Determine the influence of crop management practices on soybean root diseases.

Use standard pathological techniques to determine virulence and frequency of Phytophthora sojae races; cooperate with other soybean researchers to determine predominent P. sojae races in the North Central region, and utilize established tillage and rotation plots with a history of Phytophthora root rot and/or sudden death syndrome to enhance development of disease control strategies as they relate to crop management practices.
