Quick Guide to Soybean Varieties for Iowa with Peking SCN Resistance

By Dr. Greg Tylka 

A recent ICM News article summarized the updated list of soybean cyst nematode-resistant soybean varieties for Iowa, available online here. The publication contains information on 866 SCN-resistant soybean varieties and 5 blends available for use in Iowa for 2024. The list includes 87 varieties with Peking SCN resistance. Varieties with Peking SCN resistance can provide better SCN control and increased yields in fields where varieties with PI 88788 resistance were grown for decades. The tables below provide a quick look of varieties with Peking SCN resistance.

Consult the ISU Extension publication here for information about the herbicide resistance and iron deficiency chlorosis tolerance of the varieties.

The information above and in the ISU Extension publication was provided by the seed companies offering the varieties for sale. Variety availability changes from year to year, so an annually updated list is most helpful.
