Allelic Variation of Glu-A1 and Glu-B1 Genes in Winter Durum Wheat and Its Effect on Quality Parameters

Winter durum wheat is a relatively young crop that is highly adaptable due to its winter type of growth habit. The priority of breeding and genetic improvement of winter durum wheat is to improve grain quality and pasta quality, largely determined by the glutenin storage proteins. In the present study, a collection of 76 accessions of winter durum wheat from P.P. Lukyanenko National Grain Centre was studied. The allelic state of high-molecular-weight glutenin genes, and , using PCR markers and SDS-PAGE was identified and grain and pasta quality traits were assessed in a two-year field experiment. The positive effect of the allele and a negative effect of on the gluten index were shown. It was found that and have a positive effect on the quality and quantity of protein and gluten, while the + genotypes were closest to the high-quality category in protein-associated quality traits.
