چکیده مقاله:
To evaluate moisture-stress tolerance in reproductive growth stages in five triticale (Alamos۸۳, Lasko, Moreno, Prego, and Zorro), one bread wheat (Roshan) and one durum wheat (Osta-Gata) cultivars, two field experiments were conducted in ۲۰۰۵-۰۶ cropping season at Research Farm, Isfahan University of Technology, Lavarak, Njafabad, Iran. 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-۲, grain spike-۱, grain weight spike-۱, ۱۰۰۰ 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-۱ under both conditions. Triticale cultivars performed superior than wheat cultivars under both moisture conditions. Considering the grain yield potential, Alamos ۸۳, 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.
