ENHANCING RESISTANCE TO ROOT ROT PATHOGENS OF SOYBEAN
Crop Production and Pest Control Research
Project Number: 3602-21220-011-00
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.
