Title	Genes for resistance to Russian wheat aphid in PI294994 wheat
Journal	Crop Science
Year	1993
Volume	33
Pages	998-1001

Abstract	Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), is a major economic pest of wheat (Triticum aestivum L. and barley Hordeum vulgare L. in several western U.S states Genetic resistance is an effective strategy for protecting the wheat crop from RWA while minimizing the use of pesticides The study was conducted to determine the number of genes conferring resistance in the seedling and adult growth stages in the wheat line P1294994 and to establish whether greenhouse and field resistances were related. The resistant line PI294994 was crossed with the club wheat cultivars Moro and Hyak. F2 and F3 seedlings and F2 adult plants from the two crosses were artificially infested with RWA and evaluated for their reactions in the greenhouse and field, respectively. Seedling and adult plant reactions indicated that the resistance in the line P1294994 is controlled by two genes. Resistance is conferred by a dominant allele at one locus and by a homozygous recessive allele at the second locus. P1294994 is an effective source of genetic resistance in the field to RWA in the Pacific Northwest.
