| Comments | A line of hexaploid winter triticale Presto with an engineered rye chromosome 1R Valdy. Chromosome Valdy has an intercalary insert of 1DL in its long arm that introduces wheat locus Glu-D1 encoding high molecular weight glutenin subunits 5+10, replacing a corresponding rye segment with secalin locus Sec-3. On the short arm chromosome Valdy carries translocation WR-4 that introduces a segment of wheat chromosome 1DS with the Gli-D1 and Glu-D3 loci present. Sec-1 locus of rye remains. This translocated chromosome 1R improves breadmaking quality of triticale by up to 25%, depending on the background [2965]. |
