Genetic mapping of resistance to Diuraphis noxia (Kurdjumov) biotype 2 in wheat (Triticum aestivum L.) accession CI2401

Original language description

The RWA, Diuraphis noxia (Kurdjumov), is a devastating insect pest of wheat (Triticum aestivum L.) and barley (Hordeum vulgare) in the United States and in many parts of the world. The use of D. noxia-resistant cultivars is an economically useful approach for protecting cereals from this aphid. However, there are few genes conferring resistance to the most predominant US biotype (Biotype RWA2). Wheat line CI2401, originating from Tajikistan, has been identified to be resistant to RWA2. An F-2-derived F-3 (F-2:3) segregating population developed from a cross between CI2401 and Glupro (a high quality susceptible wheat cultivar) was used to genetically map the resistance in CI2401. Seedlings from F-2 individuals and F-3 families were infested with RWA2 aphids. Seedling reactions were scored as resistant or susceptible based on the degrees of leaf rolling and chlorosis. The observed segregation ratios in the F-2 and F-3 generations indicate the presence of a major dominant gene controlling
