“…Winter durum wheat in Central and Eastern Europe is sown in autumn and gains access to more moisture accumulated in the soil due to autumn and winter precipitation [ 16 ]; it undergoes the stages of grain setting to grain filling under less stressed hydrothermal conditions, thus the yield potential is higher than that of spring wheat [ 17 , 18 ]. To improve the competitiveness of winter durum wheat relative to spring wheat, breeding centres in southern Russia are actively performing breeding for quality [ 19 , 20 , 21 , 22 ]. Commercially successful wheat cultivars have been developed by the P.P.…”

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.

The climate is changing towards aridity. “Drought resistance” has become the most important factor. By using genetic coadaptation phenomena, it has been possible to increase the potential grain yield under these conditions up to 10,7 t/ha. This is due to significant growth of the crop yield index (from 36 to 40%). It continued increase in the case of droughts is limited by the biological yield. Using the phenomenon of transgression this problem can be solved with simultaneous obtaining the genotypes with increased top weight by reducing the coefficient of water consumption in the synthesis of metabolites. Along with this value, the photosynthesis intensity is of vital importance. It is determined by such factor as the yield to leaf area ratio. When assessing the heat and drought resistance of genotype, the following marker is used: weight of grain per plant or area. The freezing resistance issue is solved by using the transgressive selection with the sources of this specification. It usually dominates in the case of gene interaction. Despite the warming phenomena, the freezing resistance is also considered. The temperature at the tillering zone depth (-18℃) is used as the core indicator. Two methods are implemented namely: transgressions when attracting the high-yielding medium winter-hardy forms in hybridization and generation of genotypes equal to the high winter-hardy parent plant, with the use of the local frost-resistance material as one of the parent plants.

Introduction and methodology. The value of the initial material is primarily determined by the tasks of modern breeding process, collection material playing an important role in it. The purpose of the current study was to estimate the initial material of winter durum wheat according to their yield structure elements in the south of the Rostov region. The objects of research were 159 winter durum wheat samples among which there were 69 of domestic breeding and 90 of foreign one.Results. The study has shown that in 2019–2020 grain productivity of the collection samples ranged from 227.9 g/m2 to 735.9 g/m2. All studied samples were divided into three groups according to the trait ‘productive stand’ (number of productive stems per 1 m2). There were 17.6% of samples with a small value of the trait (201–400 pcs./m2); with a mean value of the trait (401–600 pcs./m2) there were 72.3% of samples and with a large value of the trait (601–800 pcs./m2) there were 10.1% of samples. According to the trait ‘plant height’ more than a half of the samples (57.0%) belonged to the ‘semi-dwarf’ group (61–85 cm). Large part (70%) of winter durum wheat samples formed ‘length of head’ in the range of 6.5–7.5 cm. In 2019–2020, number of spikelets per head ranged from 17 pcs. up to 24 pcs. The trait ‘kernel weight per head’ of the studied collection samples varied from 0.77 g to 2.08 g, all the samples had different kernel sizes. The trait ‘number of kernels per head’ varied from 22 pcs. (the variety ‘Novinka 4’) up to 51 pcs. (the sample ‘1015/16’). The trait ‘1000-kernel weight’ in the trial ranged from 23.9 g to 49.0 g, the standard variety had 34.1 g. The productivity of the collection samples was formed due to 1000-kernel weight and kernel weight per head, the correlation coefficients for these productivity elements being r = 0.45 ± 0.07; r = 0.35 ± 0.07.
