e0“The Russian wheat aphid (RWA, Diuraphis noxia Kurdjumov) is a global pest of wheat ( Triticum aestivum L.)”
e1“All plant genotypes that were RWA resistant expressed strong resistance to leaf chlorosis and leaf roll after RWA1 feeding. Results were similar for RWA2 except for the Dn4 genotype, which was equally susceptible as Yuma”

Other claims from this paper (8)
- Intervention effect Resistant wheat genotypes except Dn4 expressed strong resistance to leaf chlorosis and leaf roll after RWA2 feeding.
- Intervention effect Dn4 wheat was equally susceptible to RWA2 as the susceptible Yuma.
- Intervention effect RWA1 and RWA2 feeding reduced plant height by 50% in susceptible Yuma and Dn626580 wheat.
- Intervention effect RWA2 feeding reduced plant height and leaf growth by 50% in susceptible Dn4 wheat.
- Intervention effect Reductions in plant height and leaf growth under RWA2 feeding were below 23% in Dn7, Dn10 and Dn2414.
- Intervention effect Dn10 wheat showed strong resistance to RWA1 and RWA2 feeding damage comparable with Dn7 and Dn2414.
- Intervention effect Dn10 wheat showed less reduction in plant height under RWA1 and RWA2 feeding than Dn2401 and Dn626580.
- Recommendation The authors describe Dn10 as a potentially valuable gene for wheat breeding programs.
