A collection of 7 landraces of Palestinian durum wheat was screened for resistance to leaf rust (Puccinia triticina) under controlled conditions. Latent period was more pronounced in adult plants than in seedlings and within adult plants the latency period was higher in flag leaf. In sixth leaf stage, all lines except White Dibeyah had a relative latency period greater than Meridiano and similar to Akabozu. Black Dibeyah had a latency period superior to Akabozu (partially resistant check). Black Dibeyah, Kahatat and Akabozu had a higher percentage of early abortion without host cell abortions (EA-) than the susceptible control in seedling stage. In the sixth leaf stage, only line Black Dibeyah had a higher % EA- than the rest. In flag leaf stage lines, Black Hiteyah, Yellow Hiteyah, Black Dibeyah, Kahatat and Akabozu had a higher percentage of early aborted colonies than Meridiano. These lines may be useful additional sources of partial resistance to leaf rust and they might be used in breeding programs.
