Abstract/Summary

Field studies were conducted to determine the antixenotic resistance against the peach-potato aphid, Myzus persicae (Sulzer) in different potato cultivars i.e. Cardinal, Ultimus and Desiree. These cultivars were studied in the paired tests as Cardinal vs. Desiree and Cardinal vs. Desiree for antixenosis (systemic insecticide-based test). In Desiree vs. Ultimus, no significant difference was found for the preference of M. persicae, while in case of Cardinal vs. Desiree, there was a significant preference for Desiree. Cardinal clearly showed antixenosis to M. persicae.
