Rusts and drought are the principal yield-limiting factors for wheat production in the Central Anatolian region of Turkey. The aim of the study was to determine resistance sources in a crossing block of drought tolerant lines. Seedling tests involving all three rusts were carried out at CRIFC, Yenimahalle, in 2014. Inoculations were made with local Pgt (avirulent on differentials with Sr24, Sr26, Sr27 and Sr31), Pt (avirulent on differentials with Lr9, Lr19, Lr24 and Lr28) and a local Pst population. Reactions were scored 14 days post-inoculation on 0-4 (LR and SR) or 0-9 (YR) scales. Seventeen (19%) genotypes were resistant to stripe rust, 11 (12%) were resistant to leaf rust, and 17 (19%) were resistant to stripe rust.
