Greetings, 

I don't work much with SCN more. In the process of getting a presentation for Winter Crops Day at Waseca and Rochester, I wanted to find out how many SCN resistant soybean varieties containing the Peking source were available for MN. 

I looked through seed catalogues and the web and found that unfortunately there is no easy way to search on SCN resistance source. The table below shows the varieties I found. 

  • None were maturities adapted to Northern MN. 

  • Some of these may be the same variety with different labels. 

  • Few had been screened for level of resistance by the UMN (see 2019 variety trials) for those that have. 

  • Herbicide trait of the variety is added because a mistake in herbicide application would be... dramatic.

This might save someone else some time. I doubt that this is a complete list but I can always add varieties if I learn of more.
