The Russian wheat aphid, Diuraphis noxia, is a serious pest of wheat in South Africa. The use of D. noxia resistant cultivars may reduce the impact of this pest on cereal production, at the same time reducing environmental risks and minimizing control costs. The objective of the study was to determine the inheritance of D. noxia resistance present in the lines OSU ID 2808 (Triticum aestivum) and Aus 22498 (Triticum aestivum vavilovii) in order to ensure their judicious use in a backcross breeding programme. Resistant lines OSU ID 2808 and Aus 22498 were crossed with the susceptible cultivar Tugela after being screened with D. noxia. Resistance reactions of the F1, F2 plants and individual F2-plant derived F3 families indicated that the resistance in both genotypes is controlled by single dominant genes. It is unknown whether these genes are the same or not.
