Abstract only
The aim of this study was to determine the reactions of wheat cultivars and advanced lines from Turkey to Pgt race Ug99 and derivatives. A total of 1,800 winter and 600 spring wheat genotypes, some of which were resistant also to local Turkish Pst and Pgt populations, were tested at KARI, Kenya, in main season trials between 2006 and 2011. Winter wheat entries were vernalized in pots for 6 weeks at +40C prior to transplanting as hill plots in the field. Spring wheat entries were planted directly as twin 70 cm rows. Stem rust responses were scored twice each season for both severity and reaction type, which were converted to coefficients of infection (CI). CI levels <20 were accepted as resistant. Overall, 99 winter and 55 spring wheat genotypes were resistant to Ug99. These genotypes can be used as resistant germplasm for breeding activities.
