Brief Project Summary:

Soybean cyst nematode (SCN) is the most serious pest of soybeans in Kentucky. A survey in 2006 suggested that most of the SCN populations in Kentucky can now reproduce on Plant Introduction (PI) 88788. This PI is the genetic basis of more than ninety percent of the available SCN-resistant soybeans. Sixty percent of the SCN populations tested in Kentucky could reproduce on PI 88788 at high enough to impact seed yields. In other words, many of the SCN-resistant varieties currently grown in Kentucky are not performing up to expectations. SCN damage thresholds used in Kentucky are based on old SCN populations (races 3 and 14) that were effectively controlled by most SCN-resistant varieties....

Information And Results
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.
