Improvement of durum wheat grain quality through agronomic biofortification becomes a priority research area and an effective route to combat malnutrition. An experiment was conducted to evaluate the effect of micronutrient application to different varieties of durum wheat and seeding rate on final harvest grain quality under different growing locations. The treatments were arranged in split-split plot design where the varieties were assigned in the main plot, micronutrients into the subplots, and seeding rate into the sub-subplots. Each variety was sown at four levels of seeding rates and treated with ZnSO₄ and FeSO4 applied foliarly, both at a rate of 25 Kg ha−1 during flowering. Micronutrients were applied in the form of ZnSO₄ 7H2O and FeSO₄ 7H2O. The study confirmed that application of 25 Kg ha−1 ZnSO₄-containing fertilizer has increased mineral content from 33.04 mg Kg−1 to 56.73 mg kg−1. The tested durum wheat varieties significantly differ in their capacity to accumulate grain Zn and Fe concentrations. Higher amount of Zn (20 mg kg−1) and Fe (10 mg kg−1) were accumulated by the landrace 208304 than by Asassa, an improved commercial variety. Increasing seeding rate from 100–175 Kg ha−1 has reduced grain Zn and Fe concentrations. Grain mineral concentration was significantly lower at the Mekelle location than at the Melfa location. It can be concluded that foliar application of ZnSO₄ and FeSO4 to the landrace, acc.208304, combined with 125 Kg seeds ha−1 can produce better Zn and Fe denser durum wheat grain. This will help to combat the hidden hunger, especially in resource poor countries, where fortified foods are limited in access and unaffordable by small-scale farmers.

The 3-year experiment was concerned with the response of spring forms of common wheat (Triticum aestivum L. subsp. aestivum), durum wheat (Triticum durum Desf.) and spelt wheat (Triticum aestivum subsp. spelta L. em. Thell.) to the foliar application of a plant growth stimulant (extract from marine algae Ecklonia maxima), with the commercial name of Kelpak SL (GS), as compared to control treatment (C). The following parameters were analysed: yield of grain, yield components (number of ears, weight of 1000 kernels, number and weight of kernels per ear) and physical indicators of grain quality (test weight, uniformity and vitreosity of grain). The study showed that the level of yielding and the yield components were related primarily with the wheat genotype, but they depended also on the agro-climatic conditions and on the algae extract and control experimental treatments. The application of algae extract, compared to the control, caused a significant increase in the yields of the spring wheat species under study, on average by 7.0%. Canopy spraying with algae extract had a favourable effect on the number of ears, on he number and weight of kernels per ear, but it had no effect on the weight of 1000 kernels. The grain quality of durum wheat, spelt wheat and common wheat was affected more strongly by the weather conditions in the successive years of the study and by the genotype than by the foliar application of algae extract. The spelt genotypes were characterised by lower yields and lower grain quality than common wheat and the durum wheat genotypes.

AbstractThe grain of modern wheat cultivars has a significantly lower mineral content, including the content of copper, iron, magnesium, manganese, phosphorous, selenium and zinc. For this reason cereal breeders, are constantly searching for new genetic sources of minerals that are essential in human nutrition. Triticum polonicum, which is grown on a small scale in Spain, southern Italy, Algeria, Ethiopia and warm regions of Asia, deserves special attention in this context. The micronutrient and macronutrient content of T. polonicum versus T. durum and T. aestivum was compared in this study. Polish wheat grain was characterized by the significantly highest content of phosphorus (4.55 g/kg), sulphur (1.82 g/kg), magnesium (1.42 g/kg), zinc (49.5 mg/kg), iron (39.1 mg/kg) and boron (0.56 mg/kg) as well as a low content of aluminium (only 1.04 mg/kg). The macronutrient profile of most T. polonicum lines differed completely from that of common wheat and durum wheat. The principal component analysis supported discrimination of seven Polish wheat lines with a particularly beneficial micronutrient profile (P2, P3, P5, P7, P9, P22 and P25). These lines were characterized by the highest content of copper, iron and zinc, as well as the lowest concentrations of strontium, aluminium and barium which are undesirable in food products. The above lines can be potentially applied as source materials for breeding new wheat varieties. The results of this study indicate that Polish wheat could be used in genetic biofortification of durum wheat and common wheat.

The results of the study of five seeding rates (variants) in the cultivation of spring durum wheat Bezenchukskaya Niva with seed treatment with Scenic Combi preparation (1.4 l/t) in order to identify the optimal rate are presented. On ordinary chernozem for 2017-2020 in the arid conditions of the Volga region, it was found out that when growing a crop for winter wheat, a decrease in seeding rates contributed to an increase in the coefficient of total and productive bushiness, the weight of grain from the ear and plant, the number of grains from the ear. On average, over the years of research, the yield of spring wheat grain at seeding rates of 2.0-5.0 million/ha was 2.00-2.22 t / ha. Under favorable weather conditions, the yield advantage was the norm of 4.0-5.0 million/ha by 6.2-37 %, in the acutely arid 2.0-3.0 million / ha by 3.4-16.4 % more, compared to other options. Wheat yield was most affected by the air temperature during the growing season (r=-0.97* to -0.99*). Of the elements of the structure, the maximum conjugacy with the yield at the norms of 1.0-4.0 is noted with the number and weight of grain from the ear and plant, the height of the plants (r=0,97*-1,0**). On average, over the years of research, the highest net income was established on the variants with the norm of 3.0-4.0 million / ha-17100.4-17442.8 rubles / ha, which is 761.9-1704.7 rubles/ha (4.7-10.8 %) more than the variants with the norm of 2.0 and 5.0 million/ha. The maximum level of profitability was revealed at the rate of 1.0 million / ha-194.6 %, which is 9.6-41.3% more than the options with the rate of 2.0-4.0 million / ha. Based on the conducted research, the seeding rate of 2.0-4.0 million/ha is recommended for the cultivation of spring durum wheat for commercial purposes. In the original seed production – 1.0 and 2.0 million/ha, providing a multiplication factor of up to 57.8 kg/kg of grain.

The current paper has discussed information on the characteristics and properties of the zoned spring bread wheat varieties developed in the Federal Agricultural Scientific Centre named after V.V. Dokuchaev. The purpose of the study was to develop new spring bread wheat varieties with high productivity and grain quality, resistant to unfavorable biotic and abiotic environmental factors and adapted to the conditions of the Central Blackearth Region. In the FASC named after V.V. Dokuchaev there were developed such highly productive spring bread wheat varieties as ‘Krestyanka’, ‘Kurskaya 2038’, ‘Voronezhskaya 12’, ‘Chernozemnouralskaya 2’ and ‘Voronezhskaya 18’, which are currently approved for use in production. There were analyzed the study results of productivity, grain quality and resistance to unfavorable environmental factors in different growing periods of the varieties. There was found an unambiguous productivity excess of the developed varieties over the standard ones. The endurance of the presented varieties in unfavorable conditions indicates an increase in the stability of the main traits that characterize productivity, resistance to drought, diseases, and lodging. There has been established, that in terms of grain quality the varieties ‘Krestyanka’ and ‘Chernozemnouralskaya 2’ belong to strong wheat with potential productivity of 7.20 and 6.65 t/ha, respectively. The varieties ‘Kurskaya 2038’, ‘Voronezhskaya 12’ and ‘Voronezhskaya 18’ are valuable wheat varieties with realized productivity potential of 5.31, 5.70 and 6.96 t/ha, respectively. There has been identified that the varieties ‘Chernozemnouralskaya 2’ and ‘Voronezhskaya 18’ are recommended to sow with a seeding rate of 6.0 million germinating grains per hectare for the rapid seed reproduction and obtaining high gross grain yield, since productivity, yield of conditioned seeds, germination and 1000-grain weight at this rate was the best. The sowing dates of these varieties were early.

Improving the quality of wheat grain is an important task of agricultural production. In recent years, the production of strong and valuable wheat, necessary for the production of high-quality baking flour, has decreased. In this regard, the study of the quality of grain varieties of winter wheat in specific soil and climatic conditions of the Rostov region is becoming topical. Therefore, the purpose of our research was to study the main indicators of grain quality of varieties of soft winter wheat (protein and gluten content, flour strength, bread size from 100 g of flour) in ecological variety trials to select the best under conditions of the Rostov region. The studies were carried out on the trial fields of the Laboratory of selection and seed production of winter soft wheat of intensive type of the State Scientific Establishment “Agricultural research center «Donskoy»” (Rostov region) in 2014–2016. Seventy-five varieties were studied in the course of the research. Planting dates – optimal for implementation of agricultural and agro-technical measures. Planter – «Wintersteiger Plotseed S.» Seed placement depth – 4–6 cm. Preceding crop – black fallow. Accounting square of fields – 10 m2, double replication. Seeding rate – 4.5 million seeds per hectare. Grain quality was assessed according to the methods of the national standards of the Russian Federation. Such grain quality indicators as gluten content (according to GOST R 54478-2011), protein mass fraction (as required by GOST 108460-91), baking properties of flour (in a laboratory using the remix method) were determined. The article discusses the main indicators of the quality of grain and flour of winter soft wheat varieties in ecological variety testing and compares them. Analysis of the main indicators of the quality of varieties in trials showed that in the south of the Rostov region in 2014–2016 flour strength and gluten content were the most variable indicators. In terms of protein content (> 14.5 %), 8.0 % of the studied varieties were in full compliance with strong wheat standards; by the gluten content (> 28 %) – 7.0 %; by the flour strength (>280 e.a.) – 9.0 %. Five varieties of winter soft wheat: ‘Aksinya’, ‘Tanais’, ‘Asket’, ‘Nakhodka’, ‘Yumpa’ (Russia) with a complex of economically valuable traits are of greater interest for practical breeding in terms of improving grain quality.

Organic farming systems are often constrained by limited soil nitrogen (N) availability. Here we evaluated the effect of foliar organic N and sulphur (S), and selenium (Se) application on durum wheat, considering N uptake, utilization efficiency (NUtE), grain yield, and protein concentration as target variables. Field trials were conducted in 2018 and 2019 on two old (Cappelli and old Saragolla) and two modern (Marco Aurelio and Nadif) Italian durum wheat varieties. Four organic fertilization strategies were evaluated, i.e., the control (CTR, dry blood meal at sowing), the application of foliar N (CTR + N) and S (CTR + S), and their joint use (CTR + NS). Furthermore, a foliar application of sodium selenate was evaluated. Three factors—variety, fertilization strategies and selenium application—were arranged in a split-split-plot design and tested in two growing seasons. The modern variety Marco Aurelio led to the highest NUtE and grain yield in both seasons. S and N applications had a positive synergic effect, especially under drought conditions, on pre-anthesis N uptake, N translocation, NUtE, and grain yield. Se treatment improved post-anthesis N uptake and NUtE, leading to 17% yield increase in the old variety Cappelli, and to 13% and 14% yield increase in Marco Aurelio and Nadif, mainly attributed to NUtE increase. This study demonstrated that the synergistic effect of foliar applications could improve organic durum wheat yields in Mediterranean environments, especially on modern varieties.

The current paper has presented the study results of grain quality and pasta properties of the new and promising winter durum wheat varieties developed in the FSBSI “Agricultural Research Center “Donskoy” in 2016–2018. The purpose of the study was to evaluate winter durum wheat varieties according to such traits as grain quality and pasta properties to identify the best genotypes and recommend them for use in the breeding process and wider introduction into production. There have been identified the varieties “Yubilyarka” (96%), “Kristella” (94%), “Lakomka” (92%), “Diona” and “Yantarina” (91%) with maximum values of general hardness. All studied genotypes have formed the nature weight of grain corresponding to a first quality class (from 786–814 g/l). There have been identified the varieties “Kristella” (13.9%), “Donchanka” (13.8%), “Diona” (14.0%), “Yakhont” (14.0%), “Yubilyarka” (13.6%), “Yantarina” (13.7%), “Uslada” (13.6%), “Zoloto Dona” (13.6%), “Solntsedar” (13.9%) and “Almaz Dona” (13.5%) with protein percentage in grain corresponding to a first quality class. As a result of the study, it was found that all the studied varieties had good rheological properties of gluten and formed a DCI from 80 units (the variety “Eyrena”) to 102 units (the variety “Donchanka”) and belonged to the 2-nd group. The varieties “Diona”, “Eyrena”, “Yakhont”, “Yantarina” and “Solntsedar” had high rheological properties of dough. There have been identified the genotypes of the varieties “Donchanka” (613 μg/%), “Solntsedar” (626 μg/%) and “Almaz Dona” (630 μg/%) with the maximum concentration of carotenoid pigments, which could be used as sources to improve the trait “carotenoid content”. Throughout the years of study, the varieties were characterized by high indices of dry pasta color (4–5 points). According to a brittle strength of dry pasta there have been identified the varieties “Kristella” (775 g), “Donchanka” (774 g), “Diona” (757 g), “Yantarina” (782 g), “Solntsedar” (766 g) and “Dinas” (769 g) with the best indices of the trait. The varieties identified both by a single and by a set of traits characterizing grain quality of winter durum wheat and its final products, can be used in the breeding process as an adaptive initial material. The introduction of the best varieties into production will partly solve the problem of deficiency of high-quality durum wheat in the south of Russia.

The availability and management of N are major determinants of crop productivity, but N excessive use has an associated agro-ecosystems environmental impact. The aim of this work was to investigate the influence of N fertilization on yield and grain quality of 6 durum wheat genotypes, selected from 20 genotypes as high- and low-yielding genotypes. Two N levels were applied from anthesis to maturity: high (½ Hoagland nutrient solution) and low (modified ½ Hoagland with one-third of N). Together with the agronomic characterization, grain quality analyses were assessed to characterize carbohydrates concentration, mineral composition, glutenin and gliadin concentrations, polyphenol profile, and anti-radical activity. Nitrogen supply improved wheat grain yield with no effect on thousand-grain weight. Grain soluble sugars and gluten fractions were increased, but starch concentration was reduced, under high N. Mineral composition and polyphenol concentrations were also improved by N application. High-yielding genotypes had higher grain carbohydrates concentrations, while higher concentrations in grain minerals, gluten fractions, and polyphenols were recorded in the low-yielding ones. Decreasing the amount of N to one-third ensured a better N use efficiency but reduced durum wheat agronomic and quality traits.
