“…The influence of the wheat genepool originating from the Saratov region on the wheat breeding program in Northern Kazakhstan was described in the genetic polymorphism of Gli alleles in papers published a relatively long time ago (Sozinov, Metakovsky & Koval, 1986; Metakovsky et al, 1988). However, among Kazakh wheat cultivars with elite quality of grain, only the allele Gli-A2 q had the highest frequency of distribution, indicating for a possible genetic association with high grain quality (Dobrotvorskaya et al, 2009).…”

Background Spring bread wheat (Triticum aestivum L.) represents the main cereal crop in Northern Kazakhstan. The quality of wheat grain and flour strongly depends on the structure of gluten, comprised of gliadin and glutenin proteins. Electrophoresis spectra of gliadins are not altered by environmental conditions or plant growth, are easily reproducible and very useful for wheat germplasm identification in addition to DNA markers. Genetic polymorphism of two Gli loci encoding gliadins can be used for selection of preferable genotypes of wheat with high grain quality. Methods Polyacrylamide gel electrophoresis was used to analyse genetic diversity of gliadins in a germplasm collection of spring bread wheat from Northern Kazakhstan. Results The highest frequencies of gliadin alleles were found as follows, in Gli1: -A1f (39.3%), -B1e (71.9%), and -D1a (41.0%); and in Gli-2: -A2q (17.8%), -B2t (13.5%), and -D2q (20.4%). The combination of these alleles in a single genotype may be associated with higher quality of grain as well as better adaptation to the dry environment of Northern Kazakhstan; preferable for wheat breeding in locations with similar conditions.

The progressive study determined the gliadin 'profile' and genetic diversity based on allelic variations of gliadin-coding loci in spring soft wheat (Triticum aestivum L.) selection from Russian and Kazakh origins. A total of 139 samples obtained from a spring soft wheat collection consisting of 62 from Russia and 77 from Kazakhstan were studied. As a result of electrophoretic analysis in Russian wheat, the share of monomorphic gliadin cultivars was 63% and polymorphic was 37%. However, in the Kazakh wheat collection, the share of polymorphic gliadin cultivars was 26%. The alleles were mostly found among the Russian cultivars, i.e., Gli-А1f (46.9%), Gli-В1е (43.7%), Gli-В1b (30.8%), Gli-D1а (61.0%), Gli-А2l (17.0%), Gli-А2m (16.9%), Gli-В2o (16.1%), and Gli-D2q (19.8%). In wheat genotypes collected from Kazakhstan, the following alleles dominated, i.e., Gli-А1f (47.4%), Gli-В1е (72.0%), Gli-D1а (61.7%), Gli-А2l (25.3%), Gli-А2s (16.2%), Gli-В2r (25.7%), and Gli-D2a (40.3%). The study compiled the so-called 'ideal' electrophoretic spectrum of gliadin for several countries to visualize the 'portrait' of wheat, created based on common blocks of gliadin identified by the researchers at different times. It assumed that cultivars close to the 'ideal' spectrum in gliadin alleles should have a complex of economically valuable features. For example, the spectrum of Russian wheat consists of the blocks of components controlled by alleles, i.e., f, e, a, q, o, e. As for the Kazakh wheat, its 'ideal' spectrum (f, e, a, l, r, a) coincides with the spectrum of Russian wheat at the loci Gli-1, as Russian cultivars were often taken as parental genotypes by the Kazakhstan breeders.

“…Gli-A2q allele, which has a high percentage of occurrence in Akmola and Pavlodar regions -18.7 and 30.0 %, respectively, is of interest. It turned out that it is associated with the qualitative characteristics of grain, which are characteristic of strong cultivars of wheat (Dobrotvorskaya et al, 2009). On the other hand, it has been established that wheat genotypes with Gli-A2q allele have a long stem and low productivity (Khrunov et al, 2011).…”

The study of genetic resources using prolamin polymorphism in wheat cultivars from countries with different climatic conditions makes it possible to identify and trace the preference for the selection of the alleles of gliadine-coding loci characteristic of specific conditions. The aim of the study was to determine the “gliadin profile” of the collection of common wheat (Triticum aestivum L.) from breeding centers in Russia and Kazakhstan by studying the genetic diversity of allelic variants of gliadin-coding loci. Intrapopulation (μ ± Sμ) and genetic (H) diversity, the proportion of rare alleles (h ± Sh), identity criterion (I) and genetic similarity (r) of common wheat from eight breeding centers in Russia and Kazakhstan have been calculated. It has been ascertained that the samples of common wheat bred in Kostanay region (Karabalyk Agricultural Experimental Station, Kazakhstan) and Chelyabinsk region (Chelyabinsk Research Institute of Agriculture, Russia) had the highest intrapopulation diversity of gliadin alleles. The proportion of rare alleles (h) at Gli-B1 and Gli-D1 loci was the highest in the wheat cultivars bred by the Federal Center of Agriculture Research of the South-East Region (Saratov region, Russia), which is explained by a high frequency of occurrence of Gli-B1e (86 %) and Gli-D1a (89.9 %) alleles. Based on identity criterion (I), the studied samples of common wheat from different regions of Kazakhstan and Russia have differences in gliadincoding loci. The highest value of I = 619.0 was found when comparing wheat samples originated from Kostanay and Saratov regions, and the lowest I = 114.4, for wheat cultivars from Tyumen and Chelyabinsk regions. Some region-specific gliadin alleles in wheat samples have been identified. A combination of Gli-A1f, Gli-B1e and Gli-Da alleles has been identified in the majority of wheat samples from Kazakhstan and Russia. Alleles (Gli-A1f, Gli-A1i, Gli-A1m, Gli-A1o, Gli-B1e, Gli-D1a, Gli-D1f, Gli-A2q, Gli-B2o, and Gli-D2a) turned out to be characteristic and were found with varying frequency in wheat cultivars in eight regions of Russia and Kazakhstan. The highest intravarietal polymorphism (51.1 %) was observed in wheat cultivars bred in Omsk region (Russia) and the lowest (16.6 %), in Pavlodar region (Kazakhstan). On the basis of the allele frequencies, a “gliadin profile” of wheat from various regions and breeding institutions of Russia and Kazakhstan was compiled, which can be used for the selection of parent pairs in the breeding process, the control of cultivars during reproduction, as well as for assessing varietal purity.
