In the present research, we aimed to detect and evaluate the level of long terminal repeat (LTR) retrotransposons (WIS2, Wilma, Daniela, and Wham) intraspecific variability and intron polymorphism for beta-amylase (BAMY) genes in 37 winter and 25 spring triticale cultivars coming from European countries and the USA and 5 Finnish rye cultivars. The triticale and rye genotypes differ significantly with respect to the patterns of the four explored LTR retrotransposons. A neighbour-joining dendrogram has separated all triticale and rye cultivars into three principal clusters: all winter triticale, all spring triticale and all rye cultivars. We have proved that retrotransposon-based markers can be used for differentiation of triticale and rye cultivars.
