摘要: In Puccinia triticina, slow-rusting resistance (SRR) is a slow process of infection in the field; thus, it important to generate varieties resistant wheat leaf rust. To do so, forms inheritance and management must be identified. determine components rust (P. triticina Eriks.) leaf, seedlings 20 flour (Triticum aestivum L.) genotypes were evaluated growing chamber using P. physiological race MCJ/SP. Dormant period, size number pustules measured. The Kakatsi, Tarachi F2000, Kuruku, Jupateco+Lr34-Sr2, Oaxaca local race, Rayon F89 exhibited longer dormant period. Kuruku Kakatsi had smaller fewer per cm 2 . It concluded that genotype with high level this type can identified by measuring any SRR during seedling stage.
