The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), poses a serious threat to wheat ( Triticum aestivum L.) production in many parts of the world. This research was initiated to evaluate wheat accessions for detection of resistance to the RWA. Over 12,000 wheat cultivars and plant introductions (PIs) from the USDA‐ARS National Small Grains Collection were evaluated for reaction to RWA feeding damage. Twenty‐nine PIs from Iran, Afghanistan, and the former Soviet Union, of various agronomic backgrounds were identified as having moderate to high levels of RWA resistance. This information is useful to wheat breeders searching for sources of resistance to the RWA to incorporate into their breeding programmes.
