The distribution of alleles at the Lr34 locus associated with leaf rust resistance among winter common wheat (Triticum aestivum L.) cultivars of Ukrainian breeding was studied. Co-dominant molecular-genetic marker cssfr5 was used for detection of the allelic condition of the Lr34 locus. The cultivars with detected allele Lr34(+) were identified as potentially "resistant" and the cultivars in which detected allele Lr34(-) were identified as potentially "susceptible". The collection of the cultivars (81 ones), created in the main plant breeding centers of Ukraine was analyzed. The allele Lr34(+) was identified in 44% cultivars. Results were compared with the data about the distribution of the Lr34(+) in cultivars created in different countries.
