This study aimed to determine the common ancestry of the Egyptian population of Pst races and effective/ineffective resistance genes. Materials and Methods: Rusted wheat samples collected across Egyptian provinces were processed for race analysis. Single uredinial isolates of Pst were inoculated to 8 day-old seedlings of a core set of the World/European differential hosts and Avocet near-isogenic lines corresponding to 14 stripe rust resistance genes (Yr), i.e., Yr1, Yr2, Yr3, Yr4, Yr6, Yr7, Yr8, Yr9, Yr10, Yr17, Yr25, Yr27, Yr32 and Yr Sp. Results: Virulence phenotyping revealed the common ancestry of the current population of Pst belonging to three races i.e., Triticale aggressive (virulence to Yr2, Yr6, Yr7, Yr8, Yr10 ), PstS3 (virulence to Yr2, Yr6, Yr7, Yr8, Yr25 ) and PstS2 (virulence to Yr2, Yr6, Yr7, Yr8, Yr9, Yr25, Yr27 ). The effective genes for Triticale aggressive race were Yr1, Yr3, Yr4, Yr9, Yr17, Yr25, Yr27, Yr32, YrSp, while effective genes for PstS2 race were Yr1, Yr3, Yr4, Yr10, Yr17, Yr32, YrSp and for the race PstS3 were Yr1, Yr3, Yr4, Yr9, Yr10, Yr17, Yr27, Yr32, Yr Sp. Conclusion: The Triticale aggressive race was first detected in Egypt, while the Warrior race was not found. Resistant genes for the three detected races should be considered in breeding programmes.]]>Singh, R.P., H.M. William, J. Huerta-Espino and G.
