Abstract
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, Glu-A1 and Glu-B1, 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 Glu-A1a allele and a negative effect of Glu-A1c on the gluten index were shown. It was found that Glu-B1al and Glu-B1f have a positive effect on the quality and quantity of protein and gluten, while the Glu-A1c + Glu-B1al genotypes were closest to the high-quality category in protein-associated quality traits.
