“…Ribeiro et al (2013) reported a new x-type HMW-GS in Portuguese wheat landrace Barbela encoded at the Glu-A1 locus and named it as 1Ax1.1. A little later, this protein was described by Daskalova et al (2016) in three synthetic hexaploid lines (Triticum turgidum ssp. dicoccum/Aegilops tauschii) and their tetraploid wheat parents.…”

Four amphiploid lines (SHW) based on T. monococcum (Tm) and T. boeoticum (Tb) were crossed to T. durum varieties to generate 13 combinations. Field germination and winter survival of hybrid plants in F 2 were assessed. Among all crosses, those with SHW8A-Tb and SHW9A-Tm showed highest field germination but with different degrees of spike fragility. The variation on seed number and weight per main spike was studied in F 4-6 from SHW8A-Tb/Progres and SHW5A-Tb/Severina crosses after individual selection for these traits. Ten lines with durum phenotype from the former and three genotypes with dicoccum plant shape from the latter cross were developed. SDS-PAGE indicated the presence of HMW-GS 1Ax2*+1Aynull subunits in four lines, among which 1Ax2* was inherited from T. boeoticum acc.110 through SHW8A-Tb. Most of the selected genotypes possessed γ-gliadin45, which was relating to good end-use quality. Powdery mildew testing showed that all progenies resulted from the SHW8A-Tb/Progres were susceptible to 12 races of the pathogen, while three lines derived from the SHW5A-Tb/Severina cross behaved differently: G32 expressed resistance to six, G33 to 2, and G34 to 5 races. The selected genotypes from crosses involving SHW with T. boeoticum exhibited good breeding performance compared to tetraploid wheat parents, and might be of breeding interest to further research.

“…The total grains analysed in the beginning were 50. Synthetic hexaploid wheat (SHW) 530 was derived by crossing a tetraploid hybrid (45390/45398) to Aegilops tauschii accession 19088 (Daskalova et al, 2016). This research showed that SHW530 included two lines (530-1 and 530-2), differing only at the Glu-B1 locus, and both had a HMW glutenin pair 4t+10.1t.…”

“…Bibi et al (2012) showed a range of D-genome-encoded subunits of the Elite-II SHW subset along with superior glutenin alleles in the B-genome (1Bx7+1By8, 1Bx6+1By8 and 1Bx13+1By16). In our previous study (Daskalova et al, 2016), five subunits at the Glu-A1 (1.1), 22) and Glu-D t 1 (2+11, 4+10.1) loci were reported in nine synthetic lines (T. dicoccum/Ae. tauschii), which have not been presented in the publications for SHW till now.…”

Pure line selection for the presence of Glu-D1-4t+10.1t in high molecular weight glutenin subunits was applied in a cross between a synthetic hexaploid wheat (SHW) 530-1 (Triticum dicoccum / Aegilops tauschii acc. 19088) (2n = 42, . Grain number and seed weight per plant of selected BC 1 F 5-7 individuals accompanied this high molecular weight subunit pair to create 9 wheat genotypes. They were tested in the field and showed sufficient germination and winter survival with high seed set. Hierarchical cluster analysis divided them in two groups (four in the first, including standard wheat cultivar 'Sadovska ranozreika-4' and six lines in the second cluster). The urea / SDS-PAGE method separated the new lines in two high molecular weight glutenin variants, Glu-A1-2*, Glu-B1-7+8, Glu-D1-4t+10.1t (8 genotypes) and Glu-A1-null, Glu-B1-7+8, Glu-D1-4t+10.1t (1 genotype), displaying equal low molecular weight glutenins. All families expressed two ω-gliadin bands: the gliadin #1 originated from SHW530-1, while #2 was transferred from wheat cultivar 'Albena'. The former one appeared to be the unique gliadin subunit in the genotypes, not expressed in both wheat parents. The incorporated high molecular weight glutenin alleles might serve as new genetic resources for improving the grain quality of modern common wheat.

The article presents the results of research conducted in different soil and climatic conditions of the Middle Volga region on the influence of regulated factors, as well as environmental factors on the production process of plants of various types of spring wheat. The amount of photosynthetically active radiation (PAR) is enough to obtain yields within 12–13 tons of dry biomass or 6–7 tons of grain. Natural precipitation is able to provide 3.82–4.36 t of spring wheat grain from 1 ha, and 4.5–6.3 t/ha by the total influence of solar energy, heat and moisture supply. Natural level of soil fertility without application of organic and mineral fertilizers allows to receive about 2 tons of spring wheat grain from 1 ha. Application of nitrogen in the form of ammoniac water (N-20.5 %) increased the yield in comparison with the use of nitrogen in the form of ammoniac saltpeter: the increase was 0.14 t per 1 ha. In the conditions of grey forest soil in the Predkamye region of the Republic of Tatarstan the optimal norm of sowing of spring wheat Triticum dicoccum Schuebl (spelt) depending on the feeding background was established. Growth of yield at sowing of 6 million seeds per hectare at all levels of nutrition in comparison with sowing rate of 4 million tons per hectare was 0.18 tons per hectare against the natural background, against the estimated background of NRC on 2.0 tons of grain – 0.19 tons and 2.5 tons of grain – 0.24 tons per hectare. The maximum yield increase was received at a combination of a mineral foodstuff with an optimum norm of sowing and has made on a settlement background 2 tons of grain from hectare – 0.20 tons, on 2.5 tons of grain – 0.34 tons from hectare. Thus, the aim of our research was to develop methods of growing high yielding quality grain of different types of wheat adapted to the conditions of forest-steppe in the Volga region.
