Book excerpt: Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), is a widely distributed species in western north America, and a major economic pest of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). The objectives of this study were to : 1) determine the inheritance of seedling and adult plant resistances in a wheat line PI 294994 ; 2) establish whether greenhouse and field resistances were related ; 3) determine the effect of RWA infestation on the dry matter, grain yield, and harvest index in the crosses Moro/PI 294994 and Hyak/PI 294994 ; 4) determine whether there was a difference in the three traits between different genotypes due to RWA infestation ; and, 5) assess the degree of protection genetic resistance provided in the two crosses. The club wheat cultivars 'Moro' and 4Hyak' were crossed with PI 294994. Progenies from these two crosses were artificially infested with RWA in the field and the crosses were compared for their dry matter, grain yield, and harvest index. Plant reactions of F2 seedlings, F2 adult plants, and F3 seedlings indicated that both seedling and adult plant resistances are controlled by two genes with dominant and recessive mode of inheritance and that plant reactions in the field were the same as those in the greenhouse. Comparison of mean values of dry matter, grain yield, and harvest index showed that the three traits were affected by RWA infestation and genotype in both crosses. Resistant genotypes and noninfested population were comparable with respect to the three traits in Moro/PI 294994 but they were not in Hyak/PI 294994.
