Abstract High molecular weight glutenin subunits (HMW-GS) of wheat are important factors in the determination of bread-making quality. They are responsible for elasticity and polymer formation of wheat dough. In the present study, 43 winter and 40 spring common wheat (Triticum aestivum L.) cultivars originated from Estonia, Belarus, Finland, Denmark, France, Germany, the Great Britain, Latvia, Lithuania, the Netherlands, Norway, Poland, Russia, Sweden, and New Zealand were characterised for Glu-A1 and Glu-D1 allelic composition using PCR method. Analyses were conducted with one DNA marker for identification of Glu-D1 allele encoding subunit Dx5, three DNA markers for Glu-A1 Ax1, Ax2* and AxNull subunits. It was determined that 32 (74.4%) winter and 35 (83.3%) spring cultivars had allele Glu-D1d, and 23 (53.5%) winter and 33 (78.6%) spring — Glu-A1a or Glu-A1b alleles, which have positive effect on dough properties. Polymorphism at Glu-A1 locus was detected in 15 cultivars, and 9 cultivars were polymorphic for locus Glu-D1. The obtained results were compared with published SDS-PAGE data. Complete or partial agreements were found for 78.1% of Glu-A1 and 70.6% of Glu-D1 alleles. Rapid and accurate identification of wheat Glu-1 alleles by molecular markers can be used for selection of wheat genotypes with good bread-making potential.
