Abstract: Genes for resistance to leaf rust(Lr) in twenty-four important wheat cultivars from six wheat breeding institutes or companies were analyzed using fourteen isolates of Puccinia triticina. Six Lr genes:Lr1,Lr3,Lr13,Lr23,Lr26,Lr30 of the fourty-four tested genes were postulated as present in nineteen wheat cultivars, either alone or in combinations. Of them, Lr1,Lr3,Lr26 were the main genes for resistance to leaf rust of the tested materials. Adult plant resistance of twenty-four wheat cultivars was identified with five Puccinia triticina pathotypes in the field. Two cultivars displayed good resistance at adult stage and three cultivars with the heterogeneous response and twelve cultivars with slow-rusting resistance.
