Abstract: Leaf (Puccinia triticina; Pt) and stem (Puccinia graminis tritici; Pgt) rust are important constraints to wheat production. The leaf and stem rust resistance in the Brazilian wheat varieties ?Toropi? and ?BRS194? was evaluated using a ?Toropi/BRS194? doubled-haploid (DH) population. Parents evaluated at the seedling stage with Pt race MCJ-HN displayed infection type (IT) = ;1 for ?BRS194? and IT = 3 for ?Toropi?. The DH progeny fit a 1R:1S ratio, indicating a single Lr gene in ?BRS194? was effective against race MCJ-HN. Adult plant testing with isolate 18-96-1 CCDS found that ?BRS194? displayed an IT = 3 and ?Toropi? IT = 1?, with segregating progeny consistent for multigenic adult plant resistance in ?Toropi?. The parents and DH progeny were screened for the 1BL.1RS translocation (Sr31) with marker PE061, with ?Toropi? negative and ?BRS194? positive for the presence of Sr31. ?BRS194? was also tested against Pgt races MCCF, QTHJ, RHTS, RTHJ, TMRT, TPMK, and TTKSK at the seedling stage. BRS194 was resistant to all Pgt races, and an IT = 0 to TTKSK suggested the presence of Sr36. The presence of Sr36 in ?BRS194? was supported by the molecular marker STM773-2 (+) and ?Arthur 71? (Sr36 carrier) in its pedigree. Most resistant lines carried the Sr36-associated allele of STM773-2, while a few did not, indicating the presence of a second gene conferring resistance to TTKSK. Seedling resistance to Pgt in ?Toropi? was effective against races RHTS, MCCF, QTHJ, and RTHJ, postulated to be Sr9e. The variety ?BRS194? has effective rust-resistance genes that can be used in wheat-breeding programmes. Résumé: La rouille des feuilles (Puccinia triticina; Pt) et la rouille noire des céréales (Puccinia graminis tritici; Pgt) sont d?importants obstacles à la production de blé. La résistance à la rouille des feuilles et à la rouille noire chez les variétés brésiliennes de blé ?Toropi? et ?BRS194? a été évaluée avec une population dihaploïde (DH) ?Toropi/BRS194?. Les parents évalués au stade de plantule avec la race MCJ-HN de Pt ont affiché le type d?infection (TI) 1 pour ?BRS194? et 3 pour ?Toropi?. La progéniture DH est conforme à un ratio 1R:1S, ce qui indique qu?un seul gène Lr chez ?BRS194? était efficace contre la race MCJ-HN. Les tests effectués chez les plants adultes avec l?isolat 18-96-1 CCDS ont montré que ?BRS194? affichait un IT = 3 et ?Toropi?, un IT = 1?, avec une progéniture ségréguée cohérente avec une résistance multigénique des plants adultes chez ?Toropi?. Les parents et la progéniture DH ont été criblés pour la translocation 1BL.1RS (Sr31) avec le marqueur PE061, ?Toropi? ne possédant pas le gène Sr31 et ?BRS194? le possédant. ?BRS194? a également été testé avec les races MCCF, QTHJ, RHTS, RTHJ, TMRT, TPMK et TTKSK de Pgt au stade de plantule. ?BRS194? était résistant à toutes les races de Pgt, et un TI = 1 relatif à TTKSK a suggéré la présence du gène Sr36. Cette présence a été soutenue par le marqueur moléculaire STM773-2 (+) et ?Arthur 71? (porteur du Sr36) dans sa descendance. La plupart des lignées résistantes portaient l?allèle associé à Sr36 de STM773-2, tandis que quelques-unes, pas, indiquant la présence d?un second gène conférant la résistance à TTKSK. La résistance des plantules à Pgt chez ?Toropi? était efficace contre les races RHTS, MCCF, QTHJ et RTHJ, présumée émanant de Sr9e. La variété ?BRS194? possède des gènes de résistance efficaces contre la rouille qui peuvent être utilisés dans les programmes de sélection du blé.
