Abstrakt
The ‘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.
