Spring Wheat Variety

The article presents a short review of emmer wheat distribution throughout the whole world and the regions of Russia. The grain of emmer wheat is found rich in microelements, vitamins, nondispensible amino-acids and other useful substances. The article considers the two-year study results (2016, 2017) of the trials with emmer wheat on the central experimental plot of the Kurgansk RIA. Some separate elements of cultivation technologies of the emmer wheat variety ‘Gremme’ and the spring wheat variety ‘Zauralochka’ have been developed in three-year crop and fallow rotation on the extensive and intensive backgrounds. The variety ‘Gremme’ produced 3.4 t/ha being the largest yield during the trials, the spring wheat variety ‘Zauralochka’ gave only 2.98 t/ha. In the competitive variety-testing we studied comparative productivity of emmer wheat varieties ‘Gremme’ and ‘Runo’ with the spring wheat varieties ‘Tertsiya’ and ‘Iren’. The variety ‘Runo’ was found highly tolerant to powdery mildew, brown and stem rust, and grown without fertilizers and fungicides it was the most productive variety with 2.87 t/ha compared with the varieties ‘Tertsiya’, ‘Iren’ and ‘Gremme’ with 1.17, 1.26 and 1.72 t/ha respectively. According to the baking qualities, emmer wheat yielded to the spring wheat varieties. At the same time there is high protein content (17.5%) in the variety ‘Runo’. The preliminary results of the study show that the unhulled variety ‘Runo’ in the organic farming system claims to play a leading role in obtaining an environmentally clean grain rich in the necessary elements of nutrition.

SUMMARYWheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining and stabilizing yield for both organic and conventional producers. The present study examined the responses of three Canadian western red spring wheat varieties in sole crop and in variety mixtures to varying levels of simulated and natural competition, as well as environmental stress at one conventionally and two organically managed locations in central Alberta, Canada, between 2003 and 2005. Three modern hard red spring wheat varieties (Superb, semi-dwarf; AC Intrepid, early maturing and 5600HR, tall), along with 13 two- and three-way variety mixtures, were planted under two levels of simulated weed (Brassica juncea L.) competition at each of the eight location-years. The B. juncea weed competition treatment decreased yields at all locations. Overall yield was lowest at the certified organic farm and highest under conventional management. Sole-crop semi-dwarf Superb and all three Superb–Intrepid mixture entries consistently yielded among the highest, regardless of management system, testing location or competition treatment. The 1:1 and 1:2 Superb–Intrepid mixture entries were the most stable of all entries tested. Early season vigour was strongly associated with yield, with the strongest correlation occurring under low-moisture, low-nutrient, high-competition conditions at the certified organic farm. Spring wheat variety mixtures may provide greater stability with little or no reduction in yield, while providing greater competitive ability.

Wheat Varieties

Wheat is worldwide consumed and contributes significantly to the intake of antioxidants with beneficial healthy effects. In the precise two-year field experiments in 2008 and 2009 two varieties of wheat einkorn, two varieties of emmer wheat and three varieties of spring wheat and in 2009 in addition two other spring wheat varieties, three einkorn varieties and three emmer wheat varieties were evaluated for selenium content and antioxidants – total polyphenols (TP). Selenium content was determined by atomic absorption spectrometry with hydride generation technique (HGAAS) and total polyphenols with Folin-Ciocalteau assay. Higher selenium content in grain is related to emmer (58.9–68.4 mg/kg DM) and einkorn (50.0–54.8 mg/kg DM) varieties; in spring varieties selenium content ranged from 29.8 to 39.9 mg/kg DM. Among the varieties with high TP (expressed in gallic acid equivalents) emmer varieties prevail (584–692 mg/kg DM), less represented are einkorn (507–612 mg/kg DM) and spring wheat (502–601 mg/kg DM) varieties. Among varieties significant differences were determined. TP were significantly higher in emmer wheat varieties and one einkorn and one spring wheat variety. Between TP and Se significant linear correlation was determined (r = 0.709).

During 1997–1998, the reaction of the collections of winter and spring wheat varieties to Tilletia caries was determined. In both years the most diseased winter varieties were Simona and Sparta, the least diseased were Samara and Ilona. High variability in the level of infection was observed in some varieties (VIada, Estica, Regina, Vega). No winter wheat variety was completely resistant. The most diseased spring wheat variety was Alexandria in both years, while Grandur showed no infection. High variability in the level of infection was observed in the special trials with cv. Ina and Contra. In trials of the efficacy of seed dressing against T. caries and T. laevis there was variability only in the controls, but not in dressed variants.

Spring Wheat Variety

Pseudomonas syringae, the causal agent of basal bacteriosis of wheat, is the most dangerous wheat pathogen in Ukraine. The phytopathogen affects all parts of plants and seeds, and may be the cause of their low germination. It also causes empty-head leading to crop losses and quality decrease. P syringiae survives on host plant residues, in soil and on seed. Seed infestation can play an important role in disease epidemiology. An important component of the outer membrane and the virulence factor of phytopathogenic bacteria of the genus Pseudomonas is lipopolysaccharide (LPS), which participates in pathogenesis processes, and is responsible for toxigenicity and immunogenicity of causal agents. The strategic importance of wheat in the agrarian market of Ukraine actualizes the research into the varieties resistant to basal bacteriosis. The study aims to determine the effects of phytopathogenic bacteria Pseudomonas syringae pv. coronafaciens and P. syrіngae pv. atrofaciens, as well as their LPS on seeds of different wheat varieties. Bacterial strains were obtained from the collection of live cultures at the department of phytopathogenic bacteria of D. K. Zabolotny Institute of Microbiology and Virology of the NASU. To conduct the experiment a suspension of living cells of the pathogen with a concentration of 109 CFU / ml and LPS solution at the concentration of 5 mg/ml was used. Exposure time was 24 h. The seed germination and the length of the main root of the sprout were determined after 4 days of germination period. Phytotoxic effect of P. syrіngae cells and their LPS was investigated using two varieties of winter wheat (Discus and Huculus) and spring wheat variety of Grenny. Introduced in Ukraine wheat varieties of foreign breeding Discus, Hukulus and Grenny were characterized by moderate sensitivity to phytopathogenic bacteria P. syrinae pv. coronafaciens and P. syrіngae pv. atrofaciens, as well as to their LPS. The most resistant to the phytopathogenic effect of P. syrіngae pathovars were the grains of the variety of winter wheat Discus. Live bacterial suspensions exerted a more pronounced phytotoxic effect, compared to their LPS, towards wheat grains of winter varieties and less pronounced than LPS - towards grain of spring wheat variety.

Abstract:In model experiments in soil culture, the effect of different methods of treatment with sodium selenite on the photosynthetic activity of spring wheat variety Zlata was studied under extreme growing conditions. Under drought conditions, the inhibition of the growth of the photosynthetic surface of spring wheat plants was revealed. Under conditions of excessive water supply, a sharp decrease in the area of the assimilating surface of wheat plants was observed. The positive effect of sodium selenite solution on the photosynthetic activity of spring wheat plants was established with insufficient and excessive water supply to wheat plants.

Positive Effect

An assessment of the phytotoxicity of natural (lime, zeolite and phosphorite) minerals and their nanostructured analogues (nanostructured lime, nanostructured water-zeolite suspension (NWZS), nanostructured water-phosphate suspension (NWPS) and a spine) has been carried out. a monocotyledonous test plant (spring wheat variety Ulyanovskaya-105) has a positive effect on all studied minerals. The length of the seedling among native minerals is stimulated by lime and phosphorite, among nanominerals - nanostructured lime and NWZS. All native minerals have a positive effect on biometric indicators, among nanostructural ones – nano-lime and NWPS. Seedling biomass is stimulated only by zeolite and NWZS. Thus, native zeolite has the best data on the length of the seedling (by 48.9 %), the length of the coleoptile (by 53.6 %) and the biomass of the seedling (by 16.1 %), and in NWZS - along the root length (by 12.8 %), root biomass (by 13.5 %) and seedling biomass (by 13.7 %). Thus, according to most indicators, the best are zeolite (among native ones) and NWZS (among nanostructured minerals).
