Spring wheat nursery accessions, including 18 spring wheat lines derived in CIMMYT, Mexico, and 12 spring wheat cultivars bred in Poland, along with cultivars Frontana and Sumai 3 as resistant controls, were examined for resistance to leaf rust under field conditions. Multipathotype tests with 16 different pathogen isolates were performed for postulation of Lr genes in Polish cultivars. Besides, STS markers for resistance genes Lr1, Lr9, Lr10, Lr24, Lr28, Lr37 were analysed in the studied cultivars and lines with Thatcher near-isogenic lines as positive controls. All Polish cultivars appeared to be susceptible to leaf rust. Ten of the CIMMYT nursery lines (IPG-SW: #7, 11, 14, 21, 22, 23, 27, 29, 30, 32) and cv. Frontana were resistant in the same environment and can be sources of resistance genes. Marker for the Lr10 gene was identified in 6 accessions (IPG-SW #14, 22, 23, 29, 30, 32) exhibiting resistance to leaf rust, whereas markers for Lr1 and Lr28 genes were observed in all the examined accessions. STS markers for Lr9, Lr24 and Lr37 genes were not identified in the investigated accessions.
