Brief Project Summary:

Host resistance is the most effective and economical means to manage SCN. There are many soybean cultivars with resistance derived from PI 88788 available to Wisconsin growers. The ability of SCN populations to develop on a resistant variety, or virulence, is characterized using the Hg-Type system. To date, SCN populations from 182 farms in Wisconsin have been characterized for Hg Type and most of them are able to develop on PI 88788, Peking, or both sources of resistance. The majority of SCN populations able to develop on PI 88788 and Peking have a Female Index less than 30, indicating that cultivars with these sources of resistance are a valuable management strategy. The goal of this...

Information And Results
Project Deliverables

1. Knowledge of SCN Hg types in Wisconsin.
2. Updated management recommendations for avoiding and responding to SCN virulence shifts.
3. Educational materials about Hg Type and the virulence of SCN populations on resistant soybean cultivars in Wisconsin.

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.
