Triticale (×Triticosecale Wittmack) is a synthetic species of the Poaceae family, artificially created more than 100 years ago by crossing of wheat and rye species, mainly Triticum aestivum L. and Secale cereale L. It has been shown that the gene pool of triticale is extremely poor in terms of effective seedling resistance to wheat leaf rust caused by the fungus Puccinia triticina Erikss. Inbred line of rye L371 from the Peterhof’s Genetic Collection was described as resistant to wheat leaf rust. This line as well as a highly susceptible line L393 were used to produce wheat-rye hybrids (ABDR amphihaploids) and amphidiploids (AABBDDRR=2n) for their subsequent testing on resistance to leaf rust and genetic analysis to uncover the number of genes controlling leaf rust resistance. Moreover, the analysis of genetic markers linked to leaf rust resistance genes (Lr genes) was performed to understand the novelty of resistance genes from rye line L371.
