Twenty six wheat genotypes were evaluated for their levels of adult plant resistance to leaf rust at two different locations i.e. Shibin El-Kom and Itay El-Baroud during two successive growing seasons, i.e., 2011/12 and 2012/13. The wheat varieties Sids 12, Sids 13, Misr 1 and Misr 2, Shandweel 1, Beni Sweif 4 and Beni Sweif 5 have race-specific resistance. While, the wheat genotypes Lr 34, Giza 165, Giza 168, Sakha 8, Sakha 94, Sakha 95, Gemmeiza 5, Gemmeiza 7, Gemmeiza 9, Gemmeiza 10, Gemmeiza 11 and Sohag 3 showed high levels of slow rusting resistance. On the other hand, the other tested varieties were highly susceptible or fast rusting ones i.e. Giza 160, Giza 163, Giza 164, Sakha 69, Sakha 93, Sids 1 and Giza 139. These varieties showed higher values of final rust severity (%) and AUDPC compared to the other varieties under the same field conditions. SSR marker i.e. cslv34b allele (150 bp) for Lr 34 was used to confirm the presence of the adult plant resistance gene Lr 34 in the tested genotypes.
