Management of the soybean cyst nematode (SCN) remains a challenge for profitable soybean production in spite of widespread availability of SCN-resistant soybean cultivars. This is mainly due to the selection of SCN-virulent populations by the resistant cultivars. After a number of years of using SCN-resistant cultivars, SCN populations in most fields in Minnesota have changed to the types that can overcome resistance in the current commercial cultivars. For effective long-term SCN management, an integrated program with multiple strategies is needed. While new SCN-resistance genes will be highly useful for future SCN management, using SCN-tolerant soybean cultivars has promising potential...
Identification of SCN-resistance- and SCN-tolerance genes.
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.
