Alleles at the Gli-A3 locus in groups of ukrainian winter common wheat cultivars of different origin

Aim. The aim of the study was to analyze diversity and frequencies alleles at minor gliadin locus Gli-A3 in groups common winter wheat cultivars developed different breeding institutions Ukraine periods time. Methods. Acid polyacrylamide gel electrophoresis gliadins carried out. To identify allele cultivar Myronivska storichna, segregation a sample F2 seeds from crossing with Bezosta 1 analyzed. Results. Alleles were identified 511 Ukrainian cultivars. In addition a-d, new Gli-A3e encoding two omega-gliadins storichna. b predominate total group Differences composition revealed between some A significant reduction frequency Gli-A3b detected for Plant Breeding Genetics Institute (PBGI) V. Ya. Yuryev Production (IPP) released after 2010. Conclusions. predominant are similar Central Forest-Steppe breeding. An increase noted PBGI (the Steppe) IPP Eastern Forest-Steppe) cultivars, which may indicate its adaptive value under conditions an average annual temperature these zones.
