Brief Summary of Minutes of Annual Meeting

Short-term outcomes: Improved use of soybean varieties resistant to the soybean cyst nematode (SCN) resulting in higher yields and decreased population densities of SCN. More unbiased information on SCN resistant varieties and soybean yield in relation to SCN population density is available. Data on H. glycines virulence phenotypes across the region were shared. Outputs: Publications as reported in the "Publications" section. Michigan presented a reference handbook for growers, Soybean Cyst Nematode (SCN) Managementby D. Brown-Rytlewski, G. Bird, F. Warner and K. Barnett, was presented to the committee for discussion. The Michigan publication was submitted as part of the NC1035 project objective to develop decision-support data bases for management of SCN for the grower community Activities: Objective One: Virulence profiles for SCN populations were conducted in Illinois, Indiana, Minnesota, Ontario, Tennessee, and Wisconsin. Host resistance for managing SCN was evaluated in Ontario, Kansas, Tennessee, Michigan, Minnesota, Illinois, and Iowa. Funding for this activity was obtained from the Tennessee Soybean Promotion Board and Ontario Soybean Board. Selection pressure imposed by continuous planting of SCN-resistant varieties was studied in Arkansas, Kansas, and Wisconsin. The impact of soil disturbance and tillage on SCN was determined in Indiana, Minnesota, Tennessee, and Vermont. Soil amendments for the management of SCN were evaluated in Ontario and Minnesota. The interaction of SCN with other pests and pathogens was studies in Illinois, Indiana, Iowa, Minnesota, Ontario, and Wisconsin. Alternative host studies were conducted in Indiana and Ontario. Community structure studies were conducted in Michigan, Vermont, and Tennessee. Rotations of soybean cultivars derived from different sources of resistance were compared. Objective Two: Surveys for SCN to identify candidate fields for Tier II activities were conducted in Illinois, Michigan, Minnesota, Nebraska, North Dakota, Ontario, and Wisconsin. Field results from candidate fields for Tier II activities were compared. Funding for this objective was secured for Minnesota and Vermont. A two year multi-state experiment on soil suppressiveness was conducted. Objective Three: An SOP for screening resistant lines to SCN was developed. Lists of SCN-resistant varieties available commercially were compiled by Iowa, Illinois, Ontario, and Tennessee and provided to soybean producers. Milestones: Data on corn nematodes was presented to corn pathologists to further cooperation between the two groups. An extensive dataset consisting of 3 years of observations on SCN resistance reactions among commercial soybean cultivars and the diversity of SCN virulence phenotypes has been compiled for the North Central Region. The prevalence of SCN populations that are virulent on PI 88788, the most common source of resistance, has been documented.
