Prediction of flour breadmaking quality was verified using DNA markers in seven genotypes of winter wheat (T. aestivum L., 2n = 6x = 42, AABBDD) of different quality classes, four genotypes of triticale (× Triticosecale Wittmack, 2n = 6x = 42, AABBRR), and selected progenies of triticale Presto with the T1R.1D(5+10)-2 translocation. DNA isolated from fresh leaves (the stage of the first true leaf) was used to detect the Glu D1 5+10 allele based on the SPLAT protocol according to D’Ovidio and Anderson (1994). The presence of the Glu D1 5+10 allele was verified using a product of 450 bp size. It was detected in the wheat genotypes Athlet, Brea, Bruneta, Iris, Lívia, Mona, Sida, and in all analysed progenies derived from the Presto triticale sample with the T1R.1D(5+10)-2 translocation. Effects are discussed of other loci on the final breadmaking quality in the wheat varieties Athlet, Lívia, and Mona with Glu D1 5+10 and a lower grain breadmaking quality.
