Abstract Creating of populations with wide genotypic diversity is the basis of successful selection of promising lines. This can be achieved by involving breeding material from various ecological and geographical origins, as well as interspecific hybrids, in crossing. 14 spring common wheat (Triticum aestivum L.) varieties of CIMMYT breeding (Mexico) were researched to identify the genetic sources of economically important features. A number of these varieties proved to be the sources of adaptability to biotic and abiotic stresses and high grain quality. The yield properties of the Mexican varieties in the central Russia were at or below the standard – the ‘Zlata ’ wheat variety.

The work presents the results of the research into studying technological qualities of the grain of spring common wheat, variety Siberian Alliance, depending on the soil tillage system in grain-fallow crop rotation. The research was conducted in the northern forest-steppe of Kuznetsk Depression in the experimental plot established in 1974, in a fourcourse grain-fallow crop rotation (fallow – wheat – peas – pure barley and barley intercropped with melilot). Various soil tillage systems were applied: deep moldboard, deep combined, minimum combined, minimum moldboard. The study of grain quality took place on crops of spring common wheat by three preceding crops on bare fallow and greenmanured fallow with rape and melilot. The soil of the experimental plot was characterized as leached chernozem, medium-textured, medium humus, heavy-loam. The humus content in an arable layer was 8.2%. Crops of spring common wheat were sown with all types of soil tillage systems by the multifunction tillage and sowing machine Tom’5.1. Optimum conditions for obtaining grain of spring common wheat of high quality were formed on green-manured fallow with intercropping of melilot and rape by moldboard and minimum combined soil tillage. On average, the mass of 1000 grains amounted to 37.0-37.4 g, in 2017 – 41.0 g, natural weight – 725-751 g/l, hardness – 80-81%, content of crude gluten – 32-33%, mass fraction of protein – 15.2-15.3%. Positive correlations between indices of grain quality, r = 0,40700,6594 were established. According to the State Standard Specification P 52554-2006, cultivar of common spring wheat Siberian Alliance confirms its belonging to the strong wheat type by the quality indices obtained.

AbstractThis study was conducted to evaluate the variability of salt tolerance potentials among nine wheat genotypes representing wild and cultivated species namely Triticum turgidum subsp. durum, Triticum aestivum and Aegilops geniculata. Ionomic and photosynthetic traits were used for the screening of the studied samples when faced with four salinity levels of NaCl (0, 50, 100 and 150 mM) under green house conditions at the seedling stage. The investigated genotypes exhibited different levels of salt stress tolerance. Ionomic and photosynthetic traits underline the distinctiveness of the common wheat varieties which highlighted particular performances under salt stress conditions and showed higher tolerance potentials among the studied genotypes. Interestingly, the Vaga variety showed more ability to maintain higher K+/Na+ ratios and Pq coefficients compared with the control conditions and stable Fv/F0 and Fv/Fm ratios. Stable behaviour was exhibited by wild Aegilops accessions while durum wheat varieties have been shown to be more sensitive to salt stress. Further investigations were required for the common wheat variety Vaga, which could be useful for successful breeding and biotechnological improvement strategies concerning wheat species.

Gliadin Alleles

Using vertical electrophoresis, a set of 22 biotypes heterogeneous according to their gliadin alleles as well as their low-molecular-weight (LMW) and high-molecular-weight (HMW) glutenin subunits were identified in 10 winter wheat varieties registered in the Czech Republic. The effects of individual biotypes and their specific allelic compositions on 16 grain quality parameters were investigated. Inter-varietal differences in particular quality parameters (Zeleny sedimentation, farinograph water absorption, several values of the solvent retention capacity test) were significantly greater than the differences detected among biotypes of each variety. Special attention was given to the LMW glutenin subunits and gliadin alleles and to mutual interactions responsible for significant differences in the tested grain parameters. The results revealed at least one case of significant differences in grain quality parameters among biotypes of eight heterogeneous wheat varieties. This work unambiguously indicates that the high prevalence of wheat biotype(s) with significantly poorer values in some grain parameters can also decrease the expected technological quality of the original wheat variety. In particular, multi-line wheat varieties carrying alleles Glu-B1 (6+8) and Glu-B1 (7+9) or Glu-B3j and Glu-B3g can indicate the possibility of some significant changes in grain quality parameters.

In this article, the reaction of winter wheat varieties to fertilizers in irrigated soils in the varietal-soil-fertilizer system was studied and a feeding system was developed and recommended for each soil-climatic conditions and varieties. Appropriate fertilizer standards have been developed for each wheat variety, which have increased the germination, weeding, accumulation, tuberization, spike formation, dry mass accumulation, grain quality, and yield structure and yield of winter wheat. N250P200K200 kg/ha was obtained from Polovchanka variety of winter wheat at the rate of N250P200K200 kg/ha used in irrigated brown meadow soils, while in typical irrigated gray soils the yield of winter wheat was higher than N250P200K200 kg/ha of pure wheat with N250P200K200 kg/ha. Grain yield was 80.18 tons/ha from Tanya variety, 76.38 tons/ha from Krasnodar-99 variety and 82.32 tons/ha from Polovchanka variety under N200P150K150 kg/ha. Under the influence of the same optimal fertilizer standards, the growth and development of winter wheat, nutrient accumulation, and grain yield and grain quality are improved, and the efficiency of fertilizers is increased.

Research on improving winter common wheat varieties in the context of combining high yield and grain quality is relevant. The research aimed to evaluate and select variety samples of winter common wheat with high technological indicators of grain quality for breeding purposes. In this study, we analyzed grain from 10 variety samples of the world collection; winter wheat grain of variety ‘Aivina’ served as a standard. Soil – ordinary medium-loamy medium-thick low-humus chernozem. Wheat was grown on the experimental fields of the North Caucasus FARC in the zone with unstable moistening on bare fallow. Grain vitreousness percentage in 2019 ranged between 44.0 and 53.0 %, in 2020 – 30.5–50.0 %. In the same years, this indicator for variety-standard ‘Aivina’ was 56.0 and 48.0 %, respectively. The gluten content in the grain depended on the weather conditions and genotype. Grain of all varieties harvested in 2019, including standard ‘Aivina’, had a high gluten content (28.2–35.6 %) and corresponded to strong wheat. In 2020, the situation was absolutely different. The amount of gluten in the grain of variety samples harvested in 2020 ranged between 22.9 and 34.6 %; for ‘Aivina’, this indicator reached 26.9 %. The gluten quality in all variety samples during the years of research was typical for class 2. The variety samples were characterized by a high protein content in the grain – 16.7–20.8 % and 13.5–20.4 %; the same indicator for ‘Aivina’ was 16.7 and 15.8 %. Sedimentation rate in the variety samples was 50–81 ml and 34–64 ml; in ‘Aivina’ – 50 and 43 ml. Maximum sedimentation values were noted for the variety ‘Prestizh’. It indicates the ability to form grain, the strength of which is typical for wheat-improver. The correlation between sedimentation and gluten content (r = 0.63), as well as between sedimentation and the falling number (r = 0.73), was positive and significant during the years of research. All studied genotypes are promising for breeding new wheat varieties as sources for obtaining high-quality grain.
