Investigation of seed storage protein and bread-making quality of triticale

Abstract

The subunit composition of reduced prolamin fractions of winter triticale cultivars of different pedigrees was investigated by means of SDS-PAGE. A comparative analysis of the electrophoregram patterns of triticale cultivars and those of wheat and rye revealed that each cultivar had a unique pattern. Both the glutenin subunits of wheat and the secalin units of rye could be found in triticale cultivars. Whole-grain flour of triticale and wheat was used in baking experiments. The HMW glutenin subunit composition and baking quality of triticale cultivars were in the predicted correlation. Flour from the triticale cultivars could be used in breadmaking by mixing it with up to 30% wheat flour.
