The distribution of alleles at the Lr34 locus associated with leaf rust resistance has been studied in soft winter wheat (Triticum aestivum L.) cultivars developed in Ukraine. To determine the allelic state of the Lr34 locus, codominant molecular marker cssfr5 has been used. Cultivars with the revealed Lr34(+) and Lr34(-) alleles have been identified as potentially resistant or susceptible, respectively. A collection of 81 cultivars from the main breeding centers of Ukraine has been examined; the Lr34(+) allele has been revealed in 44% of the tested cultivars. The obtained results have been compared with general data on the leaf rust resistance of wheat cultivars from different countries.
