Abstract
Thirty-four European wheat cultivars were classified into eight groups according to their reactions to seven North American races of Puccinia graminis f. sp. tritici. Cultivars of seven groups were crossed with a variety or single gene line having similar rust reactions. These crosses indicated that the resistance of Hybrid 80-3, Stabil, and Vrakuňská (group 1) was conferred by stem rust resistance gene Sr5; Admonter Früh (group 2) carries Sr5 and an unidentified gene; Flevina (group 4) carries Sr11; Erythrospermum 974 (group 5) carries Sr5 and Sr8; Étoile de Choisy (group 6) carries an unidentified gene for moderate resistance to all the races used; and Mironovskaja 808 (group 7) and Belocerkovskaja 198 (group 8) each carry an unidentified gene. The five cultivars in group 3 were not studied genetically but they react like Marquis and may carry Sr7b.
