Drought is one of the most important constrains to crop production worldwide. Attempts to develop new cereal with high yield potential and stability have been conducted and triticale is the only successful case.In this study 9 doubled haploid (DH) and 9 corresponding F 7 lines as well as two bread wheat cultivars (Roshan and Kavir)were evaluated at research farm of College of Agriculture, Isfahan University of Technology located at Lavark-Najaf Abad in 2008. A randomized complete block design with 3 replications was used in each of two environmental conditions of irrigation after 70 and 130 mm evaporation from a Key words Triticale, doubled haploid, moisture stress, drought stress tolerance index, STI index.
