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.
