This study was carried out to investigate variation in grain yield and some quality traits of 12 bread wheat cultivars grown in zinc-deficient soil under rainfed conditions. Zinc fertilization was applied at the rate of 23 kg Zn ha-1, as ZnSO4.7H2O. Zinc application resulted in significant increase in grain yield and thousand kernel weight on average of 184 and 17% respectively, while resulting in grain protein and gluten content (3.5%) decreases. Correlation analysis indicated that, with zinc application, grain yield and protein content, thousand kernels weight and protein content had negative significant relationship, whereas protein content and gluten content had positive significant relationship.
