Outcomes of breeding triticale aiming at the improvement of bread-making characteristics of grain for making food products from yeast-leavened dough are presented. The breeding programme is based on the employment of triticale donors with translocations of chromosome 1R, to which the segments of wheat chromosome 1D were transferred. These translocations of chromosome 1R carry the glutenin allele Glu-D1d encoding HMW subunits 5+10. This allele positively affects bread-making quality. The donors of chromosome 1R translocations were provided by A. J. Lukaszewski (Univ. of California, USA). Two-year data on grain quality in selected triticale lines from 2007 and 2008 harvests are given. Most grain quality parameters in these lines are close to those of winter wheat classified into B category (bread quality). Prospects of breeding triticale for bread-making quality are discussed.
