Winter Bread Wheat

The production of winter wheat varieties, which are characterized by high productivity and sowing qualities of seeds, is one of the ways to improve productivity and gross grain harvest in the region. The current paper has presented data on the productivity, sowing qualities and biological properties of the original seeds of the winter bread wheat varieties ‘Stanichnaya’, ‘Lydia’ and ‘Asket’, grown in the laboratory for primary seed production of the Federal State Budgetary Scientific Institution “ARC “Donskoy”. The purpose of the research was to study the productivity and sowing qualities of the winter bread wheat varieties. Productivity is the main criterion for the value of a variety. It was found that with an average productivity (5.8 t/ha) of the variety ‘Stanichnaya’, the data by the years of 2018–2020 varied from 5.1 to 7.2 t/ha, and for the variety ‘Asket’, at a similar level of average value, the variation ranged from 5.2 to 6.8 t/ha. There was found that 1000-seed weight depended on the variety and climatic conditions, and not only on the cultivation technology. The leader in this indicator was the variety ‘Stanichnaya’, with an average value (44.5g) of 1000-seed weight. The maximum yield of conditioned seeds during the years of research was identified in the varieties ‘Stanichnaya’ (73.5%) and ‘Lydia’ (72.4%); the minimum was in the variety ‘Asket’ (71.7%). There was noted that the germination energy of the varieties ‘Stanichnaya’, ‘Lidiya’ and ‘Asket’ ranged from 88 to 92%. The difference between germination energy and laboratory germination ranged from 5 to 8%. When determining the intensity of the initial growth, it was found that the maximum values of the sprout length and weight of 100 dry sprouts were identified in the variety ‘Stanichnaya’ (11.0 cm and 0.63 g); the smallest values of these traits were identified in the varieties ‘Lydia’ and ‘Asket’. Field germination varied by the varieties from 73 to 82%, deviations of this trait from laboratory germination ranged from 14 to 23%. Over the years of study, for all studied varieties, the sowing qualities of seeds corresponded to GOST R 52325-2005.

Aim. To determine the adaptability of modern winter bread wheat varieties by homeostaticity and breeding value of their yields in the northeastern forest-steppe of Ukraine. Results and Discussion. The adaptability of modern winter bread wheat varieties was determined by homeostaticity and breeding value of their yields in the northeastern forest-steppe of Ukraine. It was found that, in mid-tall genotypes, homeostaticity (Hom) ranged 22.6 to 84.5 with a higher breeding value (Sc = 3.49–6.32) compared to semi-dwarf accessions (Hom = 18.9–56, 3 and Sc = 3.16–4.99, respectively). Korovaina (Hom = 84.5) and Vyhadka (Hom = 75.8) (UKR) are highly homeostatic mid-tall accessions. As to the semi-dwarf group, MV Nador (HUN) was the best in terms of this trait (V = 10.8%; Hom = 56.3). We demonstrated that the shares of the middle-homeostatic accessions were 28.6% in the mid-tall group and 30.8% in the semi-dwarf group; the shares of the low-homeostatic accessions were 57.1% and 69.2%, respectively. We selected sources with the highest breeding value for this parameter of adaptability, which exceed its average value in the experiment (Sc = 4.9). They include Metelytsia Kharkivska (Sc = 6.32), Korovaina (Sc = 6.16), Raihorodka (Sc = 6.00), Vyhadka (Sc = 5.74), Zoloto Ukrainy (Sc = 5.63), Darynka Kyivska (Sc = 5.42), and Hubernator (Sc = 5.08) (UKR). The shares of sources distinguished due to their breeding value are 50% in the mid-tall group and 38.5% in the semi-dwarf group. Conclusions. Korovaina (Hom = 84.5; Sc = 6.16) and Vyhadka (Hom = 75.8; Sc = 5.74) (UKR) are the most significant mid-tall genotypes that combine high homeostaticity and breeding value. The sources of adaptability identified in the study of homeostaticity and breeding value are valuable starting material to create new highly adaptive and promising varieties of winter bread wheat in the northeastern forest-steppe of Ukraine.

The current paper has presented the features of primary seed production of winter bread wheat in the Rostov region and highlighted the main methods of varietal renewal, which make it possible to obtain high-quality seed material with strict preservation of their purity, biological and productive traits, in the amounts that meet the needs of the farms. The purpose of the research was to organize primary seed production of new and commercial varieties of winter bread wheat, which allows maintaining varietal purity and providing the required number of seeds of higher reproductions. There have been conducted the field trials to identify the best indicators of seed productivity, varietal and sowing qualities in the primary links of seed production. Seed production is based on individual-family selection with a two-year assessment of the progeny. The main percentage of variety rejection in the laboratory conditions was made according to such indicators as 1000 seed weight, family productivity, uniformity and plump condition of kernels within the family. In PIP-1 the rejection among the varieties ‘Volnitsa', ‘Volny Don', ‘Zhavoronok', ‘Polina', ‘Ambar', ‘Donskaya Stepp', ‘Yubiley Dona' was carried out for all indicators from 16 to 32%. The variety ‘Zhavoronok' was found the best according to the indicators and its rejection rate was 7%. In PIP-2 over the years of variety trials, the studied varieties of winter bread wheat were rejected in the field for all indicators from 2 to 7%. In the laboratory conditions, the rejection rate was slightly different and ranged from 1 to 8%. The highest seed productivity was formed by the varieties ‘Zernogradka 11' (11.2 t/ha), ‘Ermak' (10.8 t/ha), ‘Marafon' (11.5 t/ha) and ‘Krasa Dona' (11.5 t/ha). The percentage of seed productivity of the studied varieties varied from 67.4% to 93.3%. The maximum 1000 seed weight was identified in the varieties ‘Krasa Dona' (52.7 g), ‘Volny Don' (49.8 g), ‘Volnitsa' (49.1 g). The indicators of the main varietal and sowing qualities of winter wheat seeds corresponded to GOST R 52325-2005.

Bread Wheat Variety

Breeding success is determined by the correct choice of agro-ecotype. In this regard, we have carried out a comprehensive estimation of 75 winter bread wheat varieties and samples of the competitive trials. The variety ‘Ermak’ was used as a standard. The study was carried out using the material and technical base of the Federal State Budgetary Scientific Institution Agricultural Research Center “Donskoy” (FSBSI “ARC “Donskoy”) in 2017–2019. The purpose was to study the correlation among economically valuable traits of winter bread wheat varieties and samples and to find genotypes similar in their parameters to the model variety based on curvilinear regressions. As a result of the phenotypic estimation of the quantitative traits of winter bread wheat varieties and samples, there was determined an average level and their variability degree. Their productivity ranged from 8.52 to 10.51 t/ha. Through the years of study, the variation coefficients indicated a high stability of these features (from 0.9 to 10.0%). In order to identify the similarities and differences between varieties and samples, there has been conducted a cluster analysis. As a result of this analysis, there has been selected the winter bread wheat variety ‘Yubiley Dona’ (C25), parameters which were more identical to the model (C76). This variety is recommended for further breeding process to improve the studied basic economic traits.

The current paper has presented the study results of SDS-sedimentation and grain quality indicators of the winter bread wheat varieties in an interstation variety testing from the research institutions of the Russian Federation, Ukraine and France. The research work was carried out in 2017–2019 in the field of the laboratory for breeding winter bread wheat, the forecrop was maize for grain. The purpose of the research was to estimate SDS-sedimentation, protein percentage in grain, quantity and quality of gluten in the winter bread wheat varieties of interstation variety testing, for the subsequent introduction of the best samples in the breeding process aimed at improving grain quality. Grain quality indicators of the winter bread wheat varieties were identified in the laboratory for biochemical estimation of breeding material and grain quality using IR spectroscopy on ‘SpektraStar 2200’ analyzer. There was established that according to the SDS-sedimentation most of the samples corresponded to strong wheat (50–63 ml). There have been identified the genotypes with the highest values of this trait, such as ‘Shef’ (58 ml), ‘Nakhodka’ (59 ml) and ‘Don 107’ (61 ml). The largest gluten content in grain was identified in the varieties ‘Don 107’, ‘Shef’, ‘Kavalerka’, ‘Timiryazevka 150’ and ‘Nakhodka’ (25.5–26.2%). The largest protein percentage in grain has been identified in the varieties ‘Don 107’, ‘Shef’, ‘Aksinya’, ‘Nakhodka’ and ‘Timiryazevka 150’ (12.5-12.8%). The varieties ‘Don 107’, ‘Shef’, ‘Nakhodka’ and ‘Timiryazevka 150’ were identified according to the studied traits and were recommended to be involved in the breeding process as parental forms.

Purpose and objectives. To evaluate the effect of sorting seeds by size on their quality indicators: germination energy, laboratory germinability and 1000-grain weight. Materials and methods. The experiments were carried out in the experimental field of the Plant Production Institute named after V.Ya. Yuriev of NAAS in accordance with the field experimentation method in 2016–2018; 26 winter bread wheat lines and varieties were studied. The varieties and lines were grown in variety trial experiments; the plot area was 10 m2. Seeds were separated on sieves of a laboratory separator RLU-3; the 1000-grain weight was measured; the laboratory germinability and germination energy were determined. Results and discussion. When winter bread wheat seeds are sorted on sieves, they are separated into fractions with various 1000-grain weights. The separated fractions of winter wheat seeds have different sowing qualities. The 2.5 x 20 mm seeds and 2.8 x 20 mm seeds are of the best quality (germination energy, germinability). It was found that in 2016–2018, the germination energy, laboratory germinability and 1000-gain weight changed depending on the growing conditions. They were the highest in 2017. The varieties with a high 1000-grain weight have been identified: Doskonala, Pryvablyva, Smuhlianka, and Haiok. The highest germination energy and germinability were intrinsic to varieties Yednist, Harmonika and Bunchuk. Yednist (93.3%), Harmonika (94.3%), Metelytsia Kharkivska (94.5%), Bunchuk (94.7%), Alians (93.3%), Podolianka (92.5%), Patriotka (93.6%), Zapashna (93.3%), Dyvo (93.7%), Doskonala (93.6%), Krasa Laniv (94.0%), Smuhlianka (93.1%), and Erythrospermum 408-13 (93.7%) had a high germinability of small seeds (2.2 x 20 mm). To clean these varieties, especially in years with low seed yields, it is recommended to use seeds of the standard size (2.2–2.5 x 20 mm). Conclusions. The relationships between the grain size and sowing qualities of seeds have been established. Separation of seeds is an effective technological method allowing for selection of top-quality seeds
