title: [Genetic differentiation of common wheat cultivars using multiple alleles of gliadin-coding loci].
abstract: The alleles ofgliadin-coding loci have been identified in 105 spring common wheat cultivars bred in Omsk and Saratov by polyacrylamide gel electrophoresis. It has been shown that 49% of the Omsk cultivars and 40% of the Saratov cultivars are heterogeneous, i.e., composed of several biotypes that differ in alleles of the gliadin-coding loci. A total of 278 genotypes have been determined (170 in the Saratov cultivars and 112 in the Omsk cultivars); in these two groups of cultivars, four genotypes are identical. Due to this heterogeneity, the cultivars bred in Omsk and Saratov can be differentiated in a statistically significant manner despite their close kinship, which allows them to be ascribed an accession to a particular breeding center based on the gliadin pattern and the number or frequency of biotypes, as well as to determine its species affiliation with a 95% probability. Close relations prevent 5% of the Saratov cultivars and 4.4% of the Omsk cultivars from being distinguished within populations, since they have identical alleles of gliadin-coding loci.
