Identification of Gliadin-and Glutenin Coding Loci in Grains of Durum Landraces and Breeding Varieties

One of the genetic markers used for the study and identification of plant genetic polimorfism is blocks of allelic components of Gliadin- and Glutenincoding Loci, which control the synthesis of reserve proteins. Protein markers such as gliadin- and glutenincoding loci controlling synthesis of reserve proteins are inherited from generation to generation as a genetically determined trait, regardless of soil-climatic and cultivation conditions and therefore can be used in the analysis of genetic diversity to assess polymorphism level and to accelerate breeding process as well. In the presented work allele component blocks of six unlinked gliadin loci - Gli1A, Gli1B, Gli6A, Gli6B and 2 glutenin loci - Glu1A and Glu1B were identified in grains of landraces and breeding varieties of durum wheat (T.durum Desf.).
