Abstract
Karyotype analysis of hexaploid triticale cultivar 'Rosner' (2n = 42 = AABBRR) revealed that its chromosome complement consists of five satellited, five median, nine submedian, and two subterminal chromosomes. In addition to Rosner, the karyotype of the F1 hybrid (2n = 28 = ABRR) obtained from the cross between Rosner and rye cultivar 'Prolific' was analysed. Since in the ABRR hybrid only the chromosomes of the R genome were present in pairs, it was possible to classify the chromosomes of rye separately from the single chromosomes of the A and B genomes of wheat. From the idiogram constructed from these studies it was demonstrated that the rye chromosomes of the Rosner karyotype were the longest of the entire haploid complement; three of these were satellited, two were median, and two were submedian in structure.Keywords
