Abstract

Wheat stern rust surveys gave evidence to the presence of nine and sixteen physiologic races in 2005 and 2006 growing season, respectively. In the first season, race 34 was the predominant (S1.980/0) followed by race 11 (25.25%). Two-hundred and two virulence phenotypes were detected among these races. The most effective resistance genes were Sr 26, 29, 11, 3.1, 35, and 9e. In the second season, race 15 was the predominant (27.26%) followed by race 11 (24.230/0). Sixty-six virulence phenotypes were detected under these races. 5r26 was the most effective gene. Most of these genes were postulated to be present, either alone or in combinations, in the genotypes tested.
