Brief Project Summary:

Soybean cyst nematode (SCN) is a destructive pathogen of soybean. Use of SCN-resistant cultivars is the main method to manage the nematode, and it has been practiced in Minnesota for about two decades depending on regions and individual farms. The SCN resistance in most current commercial cultivars is from the germplasm line PI 88788, only a few from Peking and PI 437654. Use of resistant cultivars will place a selection pressure on the nematode and result in SCN populations that can eventually overcome the resistance. The selection pressure of SCN-resistance on SCN populations may differ in different sources of resistance.

Information And Results
Project Deliverables

1. Knowledge of the occurrence and extent of SCN infestation, and frequencies of various HG Types and their distributions in Minnesota.
2. Improved understanding of the effect of different sequences of SCN-resistance sources on dynamics of SCN population densities and their virulence phenotypes (HG Types).

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.
