1a.Objectives (from AD-416)
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.
1b.Approach (from AD-416)
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.
Studies were established and substantial progress in collecting the FY2007 year-1 data for this new project has been met, however important late season field data are currently not completed.
Additional details about the research can be found in the final report for the previous project, 3602-21220-009-00D, also entitled "Enhancing Resistance to Root Rot Pathogens of Soybean"
