Folia Pomer. Univ. Technol. Stetin., Agric., Aliment., Pisc., Zootech. 309 (29), 123–132.2081-1284https://hdl.handle.net/20.500.12539/1092The ‘pontin’ translocation was obtained as a result of the recombination of segment from Thinopyrum ponticum with Lr19 gene, carrying resistance to leaf rust caused by Puccinia triticina, with chromosome segment of Thinopyrum intermedium, that contains Bdv2 gene that determines tolerance to Barley Yellow Dwarf Virus. Translocation ‘pontin’ is attractive for improvement of modern cultivars of common wheat (Triticum aestivum L.). The aim of the study was optimization of the set of molecular markers for selection of Polish breeding lines carrying ‘pontin’ translocation. We found that testing with AG15 and SCS265/253 markers is sufficient for tracing of the presence of ‘pontin’ translocation introduced from lines ER6, ER20, ER21, ER35 and IK33. As a result of the screening of over 1200 genotypes in 5 loci, lines carrying ‘pontin’ translocation were identified in materials from Choryń and Strzelce. The optimized system of selection is significant for cumulating resistance genes in selected genotypes.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskardza brunatnaselekcja wspomagana markeramiTriticum aestivumleaf rustmarker assisted selection,Triticum aestivumDyscyplina::Nauki rolniczeArticle2300-5378
