Abstract

Puccinia triticina, the wheat leaf (brown) rust agent, cause major yield losses in winter-facultative. A feasable approach to control the diesase is the use of slow rusting in cultivars. We evaluated 76 winter-facultative wheat cultivars from different countries, 40 Thatcher leaf rust isolines, and one susceptible check, Sabalan. Since slow rusting acquires the prediction of Lr genes in the greenhouse and an effective screening of cultivars against the leaf rust under field epidemy, all cultivars were tested accordingly. Various Lr genes such as Lr1 (in 7 cultivars ), Lr3 (in 15), Lr9 (in 5), Lr10 (in 10), Lr13 (in 8), Lr14a (in 8), Lr16 (in 7), Lr17 (in 2), Lr23 (in 9), Lr24 (in 3), Lr26 (in 17), Lr27(1), Lr31 (in 1) and a larger slow rusting variation were determined. Genes we determined and those from other genetic pools could most likely increase the resistance in winter-facultative cultivars and decrease yield and quality losses because of leaf rust.

Keywords: AUDPC, gene postulation, leaf rust, slow rusting, winter-facultative wheat cultivars.
