Abstract
Twenty-one European wheat varieties from the World Wheat Assortment in Prague-Ruzynĕ (Czechoslovakia) that were resistant to leaf rust were tested with Canadian leaf rust races 1, 5, 9, 11, 15, 30, 58, and 126. The patterns of rust reaction and genetic studies on representative varieties suggest that the varieties Belocerkovskaja 198, Bezostaja 1, Mironovskaja 264, Mironovskaja 808, Osetinskaja 3, Rannaja 12, Skorospelka 3b, Fertödi 293, and Sládkovičovo K 1004 have gene Lr3, the variety Halle 9H39 has gene Lr1, the varieties Erythrospermum 142, 953, and 974 I.Z.R. have genes Lr1 and Lr3, and the variety Etoile de Choisy gene Lr16. The other varieties tested (Flevina, Sambo, Stabil, Uhčetice 22/IV, and 22/V) have reactions that are different from any of those of the single gene lines tested. The varieties Weique and Salzmünder Bartweizen were resistant to all races tested.
