Variety Testing

In 2016-2018 in the competitive variety testing there was conducted the study of peas on the fields of research crop rotation of the laboratory of legumes breeding and seed-growing of the FSBSI “ARC “Donskoy” located in the zone of unstable humidity of the Rostov region (Zernograd district). The analysis of the obtained seeds was carried out in the laboratory of biochemical estimation of breeding material and grain quality of the FSBSI “ARC “Donskoy”. The objects of research were new pea lines of breeding of the FSBSI “ARC “Donskoy”, which differed in their morphological, biological and economically valuable traits and properties. During the years of research, the meteorological conditions of the vegetation period of peas were contrasting, which made it possible to objectively estimate the lines in the climatic conditions. In the competitive variety testing for the period of 2016-2018, the evaluation of new promising pea lines due to their productivity and protein percentage resulted in identification the leafless pea lines “G-1002” and “G-1003” which exceeded the standard variety “Aksaisky Usaty 5” in productivity (0.30 and 0.39 t/ha) and protein yield (0.08 and 0.10 t/ha, respectively). There is a high correlation between seed productivity and protein content (0.95). There is a low correlation between protein percentage in seeds and protein yield (0.35). There is no correlation between productivity and protein percentage in seeds (0.03). The analysis of correlations shows that pea breeding on productivity directly affects on protein yield, i. e. the larger seed productivity, the larger protein percentage. The most productive pea lines are going to be used in further breeding work.

The purpose of the current study was to identify the effect of the length of a vegetation period of the collection soybean samples on grain productivity and quality. The study was carried out in the southern part of the Rostov region in the fields of the FSBSI Agricultural Research Center “Donskoy” in 2018–2020. The climate is semi-arid with moderately hot summers. The soil is ordinary thick calcareous heavy loamy blackearth (chernozem). The forecrop was winter wheat. The objects of the study were collection soybean samples of the ARIGPR named after N.I. Vavilov. The study was carried out on 75 samples, including 52 middle early samples with 110-120 days of vegetation and 23 middle maturing samples (120-130 days of vegetation), differing in morphobiological and economically valuable traits. The analysis of a vegetation period, grain productivity and quality of the collection soybean samples has shown that in the southern part of the Rostov region the most variable trait was grain productivity (Cv = 22.5%). The less variable characteristics were protein percentage in grain (Cv = 3.8%), a vegetation period (Cv = 4.2%) and oil content in grain (Cv = 5.3%). There has been identified a positive effect of the length of a vegetation period of soybeans on grain productivity and oil content in grain for both groups of maturity, protein percentage in both groups of maturity having a negative dependence on a vegetation period. The study has shown that in the middle early group, the largest grain productivity was obtained with 117 and 118 days of vegetation, the highest protein percentage with 110 and 114 days of vegetation, and the largest oil content in grain with 118 and 120 days of vegetation. In the middle maturing group, the maximum productivity indicators were obtained for the samples with 126 and 130 days of vegetation, the maximum protein percentage with 122 days of vegetation and the maximum oil content in grain with 123 and 130 days of vegetation. The samples showing the maximum indicators will be included in further soybean breeding.

Each region is characterized by a certain set of natural conditions. Therefore, it is necessary to have varieties of forage crops that can realize soil and climatic potential of the zone and are resistant to various possible stress factors. The purpose of the research is: study the variety samples of meadow clover according to the complex of economically useful characteristics in the competitive variety testing; identify the most promising ones in the conditions of the European North of the Russian Federation. The research was carried out in 2017, 2018 and 2019 at the experimental field of FSUE “Kotlasskoe”, which is located in the south-east of the Arkhangelsk region. Such breeding methods as selection, hybridization, creation of complex hybrid synthetic populations were used to create the studied variety samples. The studies were carried out according to the guidelines of the Federal Research Center “VNIIK named after V. R. Williams” and methodology of the State variety testing of agricultural crops (under the general editorship of Fedin M. A.). Soil of the experimental plots is weakly podzolic clay, medium cultivated on Permian clays. Mid-early diploid variety ‘Niva’ was used as a standard. The experiment was laid on a bare fallow; four-fold replication. Sowing was carried out with a SKS-6-10 seeder. Variety samples were evaluated according to a set of biological and agricultural characteristics: winter hardiness, vegetation period per mowing mass, plant height, leafiness, dry matter collection, protein content, protein collection, seed productivity. Agrometeorological conditions during the years of research were different, which allowed us to obtain more reliable results in assessing studied breeding material. All presented promising breeding samples exceeded the standard one in terms of the studied basic economic and biological characteristics. According to each studied indicator, we selected the best varieties. On average, over the years of research, a comprehensive assessment allowed us to identify the most valuable varieties that can form stable feed and increased seed productivity in northern conditions. They are K-2003, SD-289, K-1809, K-1556, ‘Taezhnik’. Winter hardiness of these samples varied from 84 to 94 %, dry matter collection – from 9.0 to 9.9 t/ha, seed yield – from 256 to 309 kg/ha, protein collection – from 1.26 to 1.35 t/ha. Variety ‘Taezhnik’ was included in the State Register of Breeding Achievements in 2020 for the 2nd region.

The current paper has presented a material on agroecological estimation of the new soybean lines developed in the Agricultural Research Center “Donskoy”. As a result of the competitive variety testing in 2017–2019, five soybean lines of the middle-early ripening group were selected with a vegetation period less than 120 days, exceeding the standard variety “Don 21” in seed productivity. The temperature and water conditions during the years of study were different, which allowed evaluating the lines in contrasting cultivation conditions. Statistical data processing was carried out by B. A. Dospekhov’s analysis of variance (2012). Agroecological estimation of the new soybean lines was carried out according to S. A. Eberhart and W. A. Russell’s method (1984) and according to V. V. Khangildin’s method (1984). Based on the conducted study, there were identified the lines “L-1016” and “L-1017”, which are characterized by stabile productivity, and the lines “L-1001”, “L-1012” and “L-1013” which are responsive to the improvement of the agricultural background. The identified soybean lines “L-1016” and “L-1017” will be used in future breeding as the sources of adaptability, and the lines “L-1001”, “L-1012” and “L1013” to develop varieties of intensive type. Comparing the time cost, the need for computer technology to carry out calculations according to the methods of agroecological estimation proposed by S. A. Eberhart / W. A. Russell and V. V. Khangildin, the first method is more labor-intensive. According to the first method, the indicators of agroecological estimation must be recalculated if the number of samples changes, since they affect the final result of the calculations, but the second method does not need it. It has been recommended when working with a large number of breeding material to use the method proposed by V. V. Khangildin to speed up math calculations in agroecological estimation.

Pea (Pisum sativum L.) is a widespread leguminous crop. It is used for food purposes, as well as concentrated high-protein feed  for  farm animals.  In addition  to a great nutrition value, a balanced amino acid composition and an excellent  taste,  it  is peas that is capable to produce large grain yields even in the risky arable zone, which most of the territory of our country belongs to. The development of the new high-protein, productive pea varieties that most fully realize the soil-climatic potential and meet the requirements of agricultural production is an urgent concern of breeders. The purpose of the current study was to develop a new pea variety, adapted for cultivation in the Republic of Bashkortostan. There has been estimated the collection peas material on morphobiological and economically valuable traits. The best varieties have been used for hybridization. Among the hybridized breeding forms there has been identifed the line “L-31315/14” which possesses economically valuable traits. In 2019, this line was sent to the State Variety Testing as the variety “Pamyati Popova”. The new variety was bred by multiple individual selection from a hybrid population “K-7992” (Korea) × “Barbel”. The variety “Pamyati Popova” is a middle ripening variety with 64–78 days of vegetation period. The kernels contain 20.7–22.4% of protein. The variety is of good taste and cooking properties. Its disease and pests’ resistance is similar to that of the standard variety. According to the Competitive Variety Testing, the average yield increase of the variety “Pamyati Popova” was on 3.9 hwt/ha in 2016–2019. The largest kernel yield of the variety was 26.9 hwt/ha in 2017.

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.
