It was shown that some Snn loci may play a role in foliar disease progression under SNB infection in multiple field environments (Friesen et al., 2009) while other studies indicated known NE-Snn interactions were either inconsistent or not associated with QTL in controlling disease development in different environments when inoculated with single or a mixture of isolates (Ruud and Lillemo, 2018; Czembor et al., 2019; Ruud et al., 2019; Francki et al., 2020; Lin et al., 2020). Here, SNN is linked to infection.
