Canada Western Red Spring (CWRS) wheat lines (Pasqua*2/ND643) containing the high protein genes of Triticum turgidum var. dicoccoides were derived from a cross between cv. Pasqua and the line ND643, which served as the source of the high protein T.t. dicoccoides genes. Polymerized Chain Reaction (PCR) based DNA test indicated that 50% of the progeny lines carried specific T.t. dicoccoides genes. Wheat lines were grown over a three year period at five test locations. Wheat lines containing the T.t. dicoccoldes high protein genes averaged 0.7–1.0% higher in grain and flour protein content compared to lines without the high protein genes. Absolute amounts of monomeric and polymeric protein increased proportionally with the increase in flour protein content. The proportion of monomeric and polymeric protein was independent of the test location and of the presence of the T.t. dicoccoides genes. Location affected grain and flour protein content and all measured quality parameters, whereas the major effect of the T.t. dicoccoides genes was on grain and flour protein content. The dough rheological and baking characteristics of wheat lines with the T.t. dicoccoides high protein genes were equivalent to CWRS wheat.
