Abstract
Twelve pathotypes of Puccinia striiformis from rusted samples collected during 2004/2005. These races were designated as 2 E0, 2E22, 6E0, 6E18, 150E82, 198E150, 198E156, 6E148, 6E150, 38E134, 230E134 and 229E223. Races 2E0, 6E0 and 2E22 were the most frequency ones. Most of the races exhibited high level of virulence on the local cultivars at seedling stage. The isogenic lines carrying Yr 6, Yr 7, Yr 8, Yr 9, Yr 12, Yr 18 and Yr A are considered to be susceptible at both seedling and adult stages. On the other hand, the isogenic lines carrying Yr 1, Yr 5, Yr 15, Yr 17, Yr 27 and Yr sp exhibited high level of resistance at both seedling and adult stages with the exception of Sids-7 and Sids-9 cultivars most of the Egyptian cultivars are considered to be resistant at adult stage. The resistant line can be used as sources of resistance in the breeding program to yellow rust in Egypt.
