The article presents the results of long-term research on the creation of high oil and large-fruited sunflower varieties for use in 5 (Central Chernozem) and 7 (middle Volga) regions. Increasing the yield of sunflower oil seeds and improving their quality largely depends on targeted breeding work. Agricultural production needs highly productive precocious and early maturing varieties that are adaptable to local agroecological conditions and tolerant to the main common pathogens. Agroclimatic conditions of the region do not allow growing foreign-selected sunflower hybrids here, as they do not reach economic maturation (full ripeness). Breeders created a new high-oil (53.3%) variety of sunflower Chakinsky 100 with a yield potential of up to 50 centner per hectare in the Tambov research Institute (a branch of the I. V. Michurin Federal Research Center). The variety is included in the state register of breeding achievements in 2018 (patent no. 9648).

Early Maturing

The use of new, early maturing cultivars with high productivity potential, and availability of effective herbicides have created real preconditions for the widespread introduction of soybean in the Western and Eastern Siberia. Modern cultivars should be characterized by: high and stable yields over the years in certain soil and climatic conditions of cultivation; suitability for complex mechanization of cultivation and high quality of products. Objective of the research was to evaluate a new soybean cultivar Zaryanitsa by yield and quality potential. The cultivar is included into the State Register of the Russian Federation (Patent No 9532) in 2018 in the Eastern Siberian region (11), is recommended for production in the Krasnoyarsk region. The studies we carried out in a nursery of competitive trial of the laboratory of leguminous crops breeding of the Omsk Agrarian Scientific Center from 2011 to 2019. The cultivar Zaryanitsa is early maturing (duration of the vegetative period is about 102 days), is characterized with slow growth at initial phases of development and simultaneous maturing, does not lodge and shatter, the location of the lower pods is high. These qualities make it possible to cultivate it in the harsh climatic conditions of Siberia and annually receive conditioned seeds with minimal losses during harvesting. The yield of the cultivar Zaryanitsa was noted at the standard level of the cultivar Sibirhachka (2.38 t per ha), the oil content in seeds was increased (+1.93% to st.) in average over the research period (nine years). The cultivar is characterized as stable ( < 1) of intensive type (bi > 1). In the Omsk Agrarian Research Center the cultivar Zaryanitsa is included into a scheme of crosses as a source of early maturity, stable yield, increased oil content in seeds.

It is important that people living now remember and honor those who gave their lives for the freedom and independence of our country and those who came from the war in difficult conditions to restore the national economy of the country. In memory of those who courageously defended the independence of our great country, we named a new apple cultivar ‘Den Pobedy’ (Victory Day), which took 33 years to create. In 2020, this cultivar was included in the State Register of breeding achievements and it is recommended for cultivation in the Central-Chernozem region including Belgorod, Voronezh, Kursk, Lipetzk, Orel and Tambov regions. This cultivar was developed by crossing are quite commonly known winter cultivar ‘Veteran’ and foreign cultivar ‘Horcout’. Trees have a drooping crown. The main branches are curves. A characteristic feature of this cultivar is that the branches from the trunk depart at an angle close to straight. The main number of fruits is located on short fruit formations. Fruits are of medium weight (140 g), conical, wide-ribbed. The main color of the fruit at the time of harvest is greenish. The cover color occupies most of the surface of the fruit in the form of red blush. The fruit flesh is white, greenish of average density. The appearance (attractiveness) of the fruit is estimated at 4.4 points, and the taste - at 4.3 points (5-point rating). Fruits contain 14.7 % of sugars and 9.2 mg/100 g of ascorbic acid (vitamin C). Harvest in Orel region is in mid-September, the consumer period of fruits is until mid-March. The cultivar regularly bears fruit and has high product and consumer qualities.

Castor oil (Ricinus communus L.) is an important commercial product. The climatic conditions of Ukraine determine the possibility of growing the castor as an annual crop. At the Institute of Oilseeds NAAS studied castor collection. The aim of the work was the selection of the most promising samples of castor oil, combining a large yield potential in a narrow range of vertical distribution for optimal technological parameters of mechanical harvesting with a high content of oil in seeds and ricinolic acid in oil. In the experience of 2015-2016, the manifestation of morphological features of 17 castor bean samples was studied. The height of plants, individual samples among themselves differed more than twice. Long-brush samples of ЕР118, К374, М203, К159 are distinguished on the basis of the length of the brush. The shortest brush was observed in sample K1008. The length of the productive brush in the studied samples is from 10.7 to 32.9 cm. Most castor bean samples under favorable conditions form brushes of the second and higher orders. According to this parameter, samples of Ep118 and selection No. 38 with four inflorescences of the second order are of the greatest interest. The largest brushes of the second order are similar in size to the brushes of the first order were observed in the samples: К1127, К810, К153. The adaptability of harvesting castor beads requires that the brushes of the first and second order coincide in height with each other, since the harvester can take a maximum of 60 cm. For the sum of the productive brushes of the first and second orders, the greatest potential yield will be provided by samples K159 and K1127. Among the studied collection stands out the small seed sample K159 and the large seed samples - PRL41 and K80. The average oil content in the seeds of the collection was from 52 to 61.4%. Sample38 had the highest oil content. The content of ricinolic acid in the collection was from 70.9 to 82.9%. Samples were isolated: К134, К1008, PRL41, К430 with the content of ricinoleic acid more than 80%. The results of the study of all parameters make it possible to isolate valuable technological samples. Sample K1064 with a high technological potential of productivity, with a seed oil content of 57.2%, has a not very high content of ricinoleic acid of 74.3%. Sample K1127 with an oil content of 58.6%, a mass of 1000 seeds of 265 g, a high potential of productive brushes has a wide variation in the arrangement of brushes. Sample K134 with a oil content of 57.1%, ricinoleic acid content of 80.7% has small second-order brushes and can be used as a single-cysts in a thicker seeding.

Landrace Accessions

Maize landrace accessions constitute an invaluable gene pool of unexplored alleles that can be harnessed to mitigate the challenges of the narrowing genetic base, declined genetic gains, and reduced resilience to abiotic stress in modern varieties developed from repeated recycling of few superior breeding lines. The objective of this study was to identify extra-early maize landraces that express tolerance to drought and/or heat stress and maintain high grain yield (GY) with other desirable agronomic/morpho-physiological traits. Field experiments were carried out over two years on 66 extra-early maturing maize landraces and six drought and/or heat-tolerant populations under drought stress (DS), heat stress (HS), combined both stresses (DSHS), and non-stress (NS) conditions as a control. Wide variations were observed across the accessions for measured traits under each stress, demonstrating the existence of substantial natural variation for tolerance to the abiotic stresses in the maize accessions. Performance under DS was predictive of yield potential under DSHS, but tolerance to HS was independent of tolerance to DS and DSHS. The accessions displayed greater tolerance to HS (23% yield loss) relative to DS (49% yield loss) and DSHS (yield loss = 58%). Accessions TZm-1162, TZm-1167, TZm-1472, and TZm-1508 showed particularly good adaptation to the three stresses. These landrace accessions should be further explored to identify the genes underlying their high tolerance and they could be exploited in maize breeding as a resource for broadening the genetic base and increasing the abiotic stress resilience of elite maize varieties.

The article presents the results of a study aimed at proving the existence of systematic error in traditional calculations of long-term growth rates of agricultural production based on chain indices of agricultural production. According to the authors, the article also introduces a more accurate assessment of its dynamics with the account to the structure of the relationship between prices and the volume of agricultural production. The paper describes a theoretical model that is a methodological basis for the study and explains the discrepancy in assessing the dynamics of agricultural production using chain indices and indexes at constant prices. It allows establishing differences in the ratios of the Laspeyres, Paasche, and Lowe indices for crop and livestock production, due to factors in the formation of demand and the complex structure of the relationship between the price level and the volume of production. The adequacy of the constructed theoretical model is proved based on aggregated data that eliminated the influence of incompleteness of the initial information. As a result, it was established that livestock production is characterized by time-distributed changes in prices and quantity of products, which makes it possible to assess its dynamics using both chain indices and symmetric indices. It is proved that the dynamics of crop production cannot be adequately described using chain indices, since a positive correlation of prices of the previous period and production volumes of the current period causes an overstatement of the index in comparable prices of the previous year. Based on calculations within the proposed aggregated model, it is proved that the use of constant prices as the Lowe index weights, updated every five years, is an acceptable approximation of the Fisher symmetric index. Application of the indicated methodology for calculating the index to the data on Russian agricultural production by main types of products in 1990-2018 allowed to establish an overstatement of dynamics by 11.9%. The main difference falls on crop production (+ 19.6%), while for livestock - the differences are insignificant (-0.7%).

The early maturing soybean cultivar Triada was developed as a result of individual selection in F4 from the hybrid combination Belogorskaya × Vilana on differentiating backgrounds for traits of reduced response to day length, cold and frost resistance, drought tolerance. Additionally, the degree of cold resistance of the initial germplasm for the breeding from a cultivar Iney was evaluated by a cryosedimentation method. According to the results of the variety trials of 2019–2020, the cultivar Triada in terms of yield exceeded the standard cultivar Slavia by 0.62 t/ha. The height of plants at the latitude of Krasnodar (45°) is 95–125 cm. The new high-yielding soybean cultivar Triada is highly resistant to low air and soil temperatures, and reacts weakly to nonoptimal day lengths. This allows it to be cultivated as a main crop in the Northern Caucasian, Central Chernozem and Low Volga regions of the Russian Federation, as well as in the Republics of Kazakhstan, Uzbekistan and Kyrgyzstan at geographic latitudes from 40 to 50°.

The aim of the study is to find out the feasibility of including green manured fallow in specialized sugar beet crop rotations by comparing necessary assessment indicators with their values in a traditional crop rotation with black fallow against the background of unequal fertilization levels. The study was based on the analysis of experimental data from a long-term stationary experiment, laid out simultaneously in all fields and variants on typical chernozem in triplicate. The results are as follows: within the same fertilization levels, no significant differences in the yield of winter wheat (sugar beet precursor) were revealed, and the yield of sugar beet in a crop rotation with green manured fallow was stably higher (no more than 5 to 7%), an increase in yield relative to the control fertilizer variant (6 tons of manure per hectare per year) against the background of a double rate of manure in combination with mineral fertilizers amounted to 21.7 to 23.4% for wheat and 14.3 to 15.6% for beets with an increase in the productivity of crop rotations (in natural and value terms) by 1.2 times, but an increase in costs by 1.3 times caused an absolute decrease in the level of profitability by 23 to 25%. Differences in the assessment indicators for specific fertilization variants increased over time due to an unequal degree of soil fertility reproduction, and therefore in the fifth cycle of the crop rotation with black fallow turned out to be 1.1 to 1.3 times greater than in the green manured rotation.
