One bread wheat flour(Rezgary) and one durum wheat flour(Cham 5) with two barley flours were prepared in the laboratory using locally made disc mills, also a commercial bread flour and naked barley flours were used in this study, blends of wheat flour and barley flour were prepared at different ration. Khalouf flour (KH) was studied before and after blending it with naked barley. The rheological properties were studied using Farinograph and Alveograph, the fermentation gassing power and specific loaf volume were carried out and finally the baking tests were conducted for all flour samples. Fermentation measure and baking tests were carried out with and without TGase. Good correlation was found between water absorption and (r=0.850 P<0.01) gassing power after five hours fermentation. Increasing dough stability and softening by addition of barley flour. The specific loaf volume (SLV) of bread decreased with the addition of barley flour and was more pronounced with white barley. The alveograph data for KH flour and its blends showed a high negative correlation of P/L with specific loaf volume (SLV) (r= -0.981 P
