Project Summary

Soybean cyst nematode (SCN) is a persistent threat to growers throughout Minnesota. Fields infested with SCN are more susceptible to other disease, pest, and environmental stresses. Moreover, some parts of Minnesota have seen a breakdown in varietal resistance, with the appearance of new SCN races capable of overcoming the widely grown 88788 source of resistance. With this in mind, our overall objective is to advance the development of SCN-resistant soybean varieties as well as provide accurate and unbiased sources of information on the resistance of commercial soybean varieties. Our specific aims are to: 1) Enhance the efficiency and efficacy of breeding for SCN resistance through the deployment of DNA markers linked to major genes conferring SCN resistance; 2) Advance new sources of SCN resistance and expand the use of these new sources for crossing in the breeding program; 3) Conduct SCN bioassays on commercial varieties entering the 2019 UMN Variety Trials and publish the results through the MN Ag Experiment Station.
