Stem rust (Puccinia graminis f.sp tritici) is a severe widespread disease of wheat in Egypt. The present investigation is concerned with the evaluation of fifteen wheat cultivars for slow rusting at seedling and adult stages. The obtained results indicated that, Beni-Sweif-4, Beni-Sweif-6 and Misr-1 wheat cultivars proved to be highly resistant which exhibited the longest incubation period and latent period at seedling stage under greenhouse conditions. While, Sids-12 and Giza-168 cultivars proved to be resistant which showed intermediate incubation as well as latent periods as indicated by the lowest No. of pustules/cm2 and pustule size. The cultivars Gemmeiza-10, Genuneiz-7, Sids-13 and Gemmeiza-11 showed intermediate incubation and latent periods and exhibited moderate resistant reaction (infection type 2), intermediate No. of pustules/cm² and pustule size. On contrast, Sids-6 showed the shortest incubation and latent periods and the highest susceptible reaction. At adult stage, Gemmeiza-11, Sids-13 and Beni-Sweif-5 proved to be highly resistant cultivars during the two tested seasons (2009-2010 and 2011-2012).
