The genotypes were sown in two normal and moisture stress after mid-booting growth stage, conditions-using randomized complete block design with three replications in each moisture regimes. Agro-morphological traits including plant height, spike no. m-2, grain spike-1, grain weight spike-1, 1000 grain weight, grain yield, biological yield and harvest index were measured and recorded. A significant and positive correlation was observed between grain yield and grain weight spike-1 under both conditions. Triticale cultivars performed superior than wheat cultivars under both moisture conditions. Considering the grain yield potential, Alamos 83, Lasko, Moreno, and Zorro cultivars were ranked as the superior group of drought tolerant genotypes. Nevertheless, Moreno was identified as a triticale cultivar that could be grown under both normal and moisture stress conditions with high grain yield.
