Triticale (X Triticosecale Wittmack) is a hybrid crop combining the high quality of wheat and the abiotic tolerance of rye. In this study, its physicochemical quality and processing-related characteristics were analyzed by cultivars and grain-processing types (whole grain, flour, and bran). The milling yield of eight Korean triticale cultivars was in the range of 57.4～66.9%, which was lower than that of Saekeumkang wheat (73.3%). Significant differences in the general nutritional components were observed by cultivars and grain-processing types (P<0.0001). The average crude protein and crude lipid contents were high in descending order of bran, whole grain and flour. Five band pattern groups identified by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis confirmed the genetic differences of high-molecular-weight glutenin profiling. The higher protein content in the triticale flour resulted in a higher level of gluten content, and affected the SDS-sedimentation values and dough strength measured on a farinograph. The total dietary fiber contents in the whole grains of some cultivars of Choyoung, Joseong, and Shinjoseong were higher (>14%) than others. Domestic triticale needs extensive research beyond the scope of traditional use on its potential as a new source of industrial raw material.
