There have been studied physical, flour-milling, technological features of the grain of the new varieties and lines of winter soft wheat developed by the FSBSI “Agricultural Research Center “Donskoy”. The purpose of the study is to identify samples with high quality of grain, flour, rheological properties of dough and baking profits. High values of grain unit and general vitreousness of grain are revealed. The samples “1237/13” (14.6%), “1261/13” (14.5%) and “Nakhodka” (14.5%) formed protein content at the level of strong wheat of the 1st class (not less than 14.5%). The varieties “Tanais” (30.9%), “Aksiniya” (30.2%), “Nakhodka” (29.5%), “Donskaya step” (28.6%) and the line “1261/13” (28.4%) showed high content of gluten in the grain of the 2nd class of quality. The studied varieties and lines of winter wheat were characterized by a high yield of flour, more than 70%. The maximum yield of flour was obtained in the varieties “Tanais” (74.5%), “Ermak” (74.1%) and the line “1261/13” (74.2%). According to the color, the flour of the samples (54.0–80.0 conventional units) “Aksiniya” (55.64 conv. units), “Nakhodka” (55.18 conv. units), “Kipchak” (54.01 conv. units), “Bonus” (54.90 conv. units), “Kazachka” (54.40 conv. units) and the line “1261/13” (54.30 conv. units) corresponded to the highest grade. There were identified variety differences in flour color and ash content, which the quality of the end product largely depends on. The 6 studied varieties “Yubiley Dona” (342 u. a.), “Nakhodka” (311 u. a.), “Shef” (292 u. a.), “Kipchak” (290 u. a.), “Tanais” (289 u. a.) and “Aksiniya” (289 u. a.) showed high rheological properties of the dough at the level of strong wheat. There were identified the samples with high yield of bread “Nakhodka” (705 ml), “Aksiniya” (695 ml) and “Donskaya Step” (685 ml), which corresponded to the class of strong wheat. The identified varieties and lines can be used in the breeding process as the sources with high grain quality and baking properties.
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 article presents the results of productivity and grain quality of 47 winter durum wheat varieties of various ecological origin studied in 2016–2018. All studied samples belong to semi-dwarf and dwarf forms (height of 61–105 cm). Semi-dwarf forms possessed high lodging resistance (3.9 points). The grain harvest of the main part (89.3%) of the samples ranged from 8.41 to 9.65 t/ha in the environmental test. Only three varieties (“Lazurit”, “Agat Donskoy”, “Andromeda”) in the winter durum wheat trial are characterized with high yields ranging from 9.65–10.0 t/ha. The yield of the standard variety of “Khristella” was 9.03 t / ha on average in 2016- 2018. The varieties “Kondor” (116.8%), “Zolotko” (123.0%), “Afina” (126.9%) showed high frost tolerance of the plants through the years of research, in comparison with the standard variety “Donchanka” (100%). In the ecological test the main part (68%) of winter durum wheat varieties possessed large grain. “1000-grain weight” was more than 40 g: “Amazon” (42.9 g), “Lazurit” (47.7 g), “Diona” (42.1 g), “Alyi Parus” (43.7 g), “Dnepryana” (45.4 g), “Krupinka” (46.9 g), etc. The studied samples had high percentage of protein (13.6–15.1%), gluten (22.8–27.0%), SDS-sedimentation (30–45 ml), carotenoids (468–779 μg/%), nature weight (777.0–819.0 g/l), kernel hardness (85–98%). The technical and culinary qualities of the pasta made from the main part of the samples were evaluated as excellent (the varieties “Donchanka”, “Oniks”, “Kiprida”, “Atoll”, “Kermen”, “Winter Gold”, etc.) and as good (the varieties “Teya”, “Eirena”, “Lazurit”, “Diona”, “Alyi Parus”, “Krupinka”, “Afina”, etc.).
Grain quality of winter bread wheat is an urgent issue in Russia and in the world. The traits and properties of grain that characterize the quality are formed in the field under the effect of weather and climatic conditions. The current study was carried out in 2017–2019. The objects of the study were 12 varieties and 3 promising lines of winter bread wheat of the Competitive Variety Testing. The variety ‘Ermak’ was used as a standard variety. The purpose of the study was to carry out a comparative estimation of grain quality of the varieties and promising lines of winter bread wheat, to identify the variation of traits over the years and to determine the effect of growing conditions on the formation of grain quality. There has been established that the studied varieties and lines formed nature weight from 799 g/l (the variety ‘Aksiniya’) to 830 g/l (‘Yubiley Dona’) and corresponded to the 1-st quality class. There have been identified the varieties ‘Etyud’ (62%; Cv = 6.6%), ‘Ermak’ (62%; Cv = 7.0%) and the line ‘1005/14’ (68%; Cv = 8.1%) with a combination of high values of the general hardness and insignificant variation of the trait over the years. There has been determined that the variety ‘Nakhodka’ (14.11%; Cv = 3.6%) and the line ‘1261/13’ (14.10%; Cv = 6.1%) were characterized by the maximum protein percentage and low values of the coefficient of variation. There has been established that the varieties ‘Aksiniya’ (4.5 points; 7.9%) and ‘Tanais’ (4.0 points; 2.5%) combined a high baking value with the stability of the trait. When estimating the effect of the factors “genotype”, “year of study” and their correlation on the characteristics of grain quality, there has been found that general hardness (52.59%), mass fraction of grain protein (58.31%), dough deformation (57, 78%), valorimetric value (46.01%), volume of bread (41.77%) and general baking assessment (51.24%) were largely dependent on genotype. The growing conditions had an effect on the formation of the quantity and quality of gluten and the P/l ratio.
The study of grain quality at all stages of a variety development, starting with the selection of parental pairs, is the most important condition for the efficiency of breeding. The purpose of the current paper was to estimate winter wheat samples according to the main criteria of grain quality and to select promising ones for further use in the breeding process. The study was carried out in 2019–2021. There were studied new varieties and promising lines of winter bread wheat from the main Competitive Variety Testing, according to green manure fallow. Criteria characterizing grain quality were determined in the laboratory conditions in accordance with methodology and GOSTs. Based on the conducted study, there were identified sources that were characterized by a high severity of grain quality traits. According to ‘grain unit’, there were distinguished such varieties as ‘Matritsa’, ‘Rubin Dona’ and the lines ‘1043/17’ and ‘1582/166’. According to the general kernel hardness there were identified such samples as ‘Matritsa’, ‘Priazovie’ and the line ‘1582/16’. The samples and lines ‘Ermak’, ‘Razdolie’, ‘Rubin Dona’, ‘Matritsa’, ‘Priazovie’, ‘1582/16’, ‘1043/17’, ‘1295/18’, ‘1431/18’, ‘1463/18’, ‘1518/18’, ‘1612/18’ and ‘1895/18’ corresponded to good quality according to SDS-sedimentation. The sample ‘1463/18’ was characterized by a high protein percentage in grain (15.02 %). There were also studied a quantity and quality of gluten, falling number and baking properties. The varieties ‘Rubin Dona’, ‘Matritsa’, ‘Priazovie’ and the lines ‘1582/16’, ‘1463/18’ were characterized by the best expression of the studied traits of quality. These genotypes can be used in the breeding process as sources of high protein and gluten percentage in grain and good baking properties.
