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.

Study Results

One of the factors to improve grain quality of winter wheat is to develop and introduce new varieties of high productivity, good grain quality adapted to the local conditions. The article presents the study results of traits of grain quality and drought tolerance of winter soft wheat varieties in the initial periods of plant growth. It has been determined that all studied varieties are characterized with large grain unit. According to mass share of protein the analyzed samples belong to the 2-d and 3-d quality grades. The variety ‘Zhavoronok’ showed the maximum mass share of protein in kernels (14%). On gluten content in kernels the varieties ‘Asket’ (24.6%, ‘Volnitsa’ (24.5%) and ‘Zhavoronok’ (24.3%) formed the grain with good indexes of the trait. The estimation of heat resistance degree in the initial periods of plant growth identified that the indexes ranged from 80.6% to 96.9%, and drought tolerance ranged from 37.1 (the variety ‘Donskoy Mayak’) to 82.3% (the variety ‘Krasa Dona’). The varieties ‘Krasa Dona’ (254.2 r. u.), ‘Ermak’ (253.5 r. u.), ‘Asket’ (251.0 r. u.) and ‘Volnitsa’ (240.6 r. u.) demonstrated high indexes of complex resistance (ICR). The largest yields of grain on average through the years of study were produced by the varieties ‘Krasa Dona’ (8.4 t/ha), ‘Kaprizulya’ (8.3 t/ha), ‘Lilit’ (8.2 t/ha), ‘Zhavoronok’(8.1 t/ha), ‘Polina’(8.1 t/ha) and ‘Volny Don’(8.0 t/ha). Due to the conducted study the new genotypes ‘Volnitsa’, ‘Zhavoronok’ and ‘Krasa Dona’ have been identified which produced high yields and quality of grain and possess high resistance to overheat and dehydration of fibers that allows using them in the breeding process as the sources of useful traits and properties.

Abstract Oil recovery from a reservoir involves quite a lot of challenges related to well placement before any action can be taken. An important step is proposing a reservoir target area that provides an indication of high potential for oil recovery. In other words, a position presenting high productivity potential according to some criteria. A simple proposal is the potential productivity proxy function (PP) based on the oil-bearing and mobility capacities of oil suggested as $$\phi k{S_{\rm o}}^n$$ ϕ k S o n , where n is a correlation parameter, $$\phi$$ ϕ is porosity, k is absolute permeability and $$S_{\rm o}$$ S o is oil saturation at grid block. In this paper, we consider this proxy function as a well placement strategy based on the column-wise ($${\text {PP}}_{\rm C}$$ PP C ) and layer-wise ($${\text {PP}}_{\rm L}$$ PP L ) values. To test this model, the UNISIM-I-D and PUNQ-S3 synthetic reservoirs are considered. Several production simulations are realized assuming a set of vertical wells placed at the best $${\text {PP}}_{\rm C} \cap {\text {PP}}_{\rm L}$$ PP C ∩ PP L , supported by the additional considerations of minimizing the water saturation and respecting a minimum distance between wells. The results, compared to the production of the original grouped UNISIM-I-D and grouped PUNQ-S3 wells, show a reasonable performance of the PP strategy for well placement. In addition, the net present value shows that the proposed wells are economically feasible. The study provided that under certain conditions, $${\text {PP}}_{\rm C} \cap {\text {PP}}_{\rm L}$$ PP C ∩ PP L is an alternative approach to find out target positions exhibiting a high productivity potential for well placement appropriateness and oil recovery.

It is known that the breeding process is in a great need for fast methods, working on minimal weights of experimental material and revealing the qualitative potential of the varieties. For this purpose, in order to get rid of unpromising numbers, the laboratory assessments widely use a sedimentation analysis, this type of analysis being the main one at the primary stages of breeding and when estimating winter wheat in the pre-harvesting period. The purpose of the current study was to identify the most valuable genotypes in seed plots by sedimentation analysis to optimize the breeding process of winter bread wheat for grain quality. The sedimentation index was estimated by the method using a 2% surfactant (SAS) solution of the sodium dodecyl sulfate (SDS) and 9.4% lactic acid. Gluten content and its quality, volumetric bread yield and falling number were assessed according to generally accepted methods. For the most accurate interpretation of the study results there has been used a one-way analysis of variance. The range of variation of the sedimentation index in the seed plot of CVT was 35–57 ml (2017); 50–83 ml (2018); 56–84 ml (2019); in KP-1 it was 44–95 ml (there were analyzed 945 samples); in KP-2 it was 50–94 ml (there were analyzed 100 samples). Inthe studied seed plot of CVT, which was laid fallow, 25 of 36 variety samples were very strong in quality; 7 ones were strong; 4 ones were medium; there were not identified any satisfactory and weak samples. As for the seed plot KP-2, 88 of 100 were very strong, 11 ones were strong and only one sample was average in quality. In the seed plot KP-1 480 of 945 were very strong (51%); 440 samples were strong (46%), and only 3% (25 pieces) were average in quality; there were not identified any satisfactory and weak samples.

Relevance. Each sample is characterized by a number of biological features, due to the recombination of genetic material in the process of its selection. These features are manifested in the reaction of plants to soil-climatic and technological conditions, expressed in the change of the elements of the yield structure and indicators of the level of adaptability of plants to growing conditions, as well as resistance to lodging. New samples have little-known properties that need to be studied and compared in specific soil and climatic conditions, to assess them in order to decide on the possibility of their zoning or culling. The main indicators characterizing the level of agricultural production are productivity, resistance to lodging, since the shortage of grain as a result of lodging of cereals can reach 15-40%. The introduction of new high-yielding varieties on the basis of their testing and the use of the most effective technological methods of cultivation on crops will allow to receive a significant gross harvest.Materials and methods. The study was carried out in 2016-2018 to assess models of cultural hexaploid species of oats hulled and naked forms of resistance to lodging, yield and adaptability in the temperate continental climate of Central non-Chernozem zone. Resistance to lodging, yield variability, indices of environmental conditions and adaptability were determined. The main method of evaluation of the field resistance to lodging – visual (in points) that allows you to rank the varieties based on this characteristic. We were calculated potential productivity and adaptability of varieties by method L. A. Zhivotkov et al. [1], an indicator of the stability level of the sample yield (Puss) by the method of E. D. Nettevich et al. [2].Results. Many varieties showed good plasticity and high productivity potential. The best in resistance to lodging, yield and adaptability among the hulled forms were varieties Sig, Mirt, Poseidon, Belinda, Rajtar, and the naked forms – Becas, Vyatsky, Korolek.
