The current paper has presented the characteristics of the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy”. Winter wheat is the most valuable grain food crop grown in vast areas. Breeding plays an important role in increasing production volume and improving grain quality as the basis of the country’s food fund. Expanding grain crops area, among which wheat predominates, there is a problem of crop rotation. Therefore, the development of unified varieties capable of producing stable high grain yields after various forecrops is one of the most urgent areas of breeding work for winter bread wheat. The purpose of the current study was to characterize the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy” according to the main economically valuable traits. Due to the intensive breeding work over the past decade, on the basis of some of the best zoned varieties ‘Ermak’, ‘Stanichnaya’, ‘Donskoy syurpriz’ there was developed a number of new promising genotypes, which are already being used in production sowings of winter wheat in the Rostov region and other regions of our country. The new winter bread wheat varieties of unified type ‘Lydia’, ‘Kapitan’, ‘Lilit’, ‘Krasa Dona’, ‘Volnitsa’, ‘Volny Don’, ‘Zhavoronok’ and ‘Polina’ are more productive than their parental forms. In combination with grain of high quality, resistance to bio and abiotic environmental factors, they are very valuable, beneficial for cultivation and improvement of the production of commercial wheat grain of high quality.

Under market conditions, the increase in wool and lamb production should not only increase the livestock number, but also increase its productivity. The significant reserve is also to improve the quality of raw materials produced. The aim of the research was to identify the features of wool and meat productivity in young rams of the Taurian type Askanian fine fleece breed the taking into account an in-depth assessment of the washed fiber yield and subsequent use of the obtained data in the selection-breeding work with sheep. The young rams of the Taurian type Askanian fine fleece breed were used for research. The formed groups were characterized by low, medium and high yield of washed fiber. The results of the studies showed an advantage in all research parameters in young rams with an average yield of washed fiber. Therefore, it is proposed to direct the selection-breeding work to improve live weight and physical and mechanical properties of wool in young rams with high yields of washed fiber (more than 60.1%), which will allow to obtain more profits not only from the wool sale but from the sale of mutton, and to reject lambs with a low washed fiber yield to prevent the transmission of this trait to their offspring.

The aim of this work is to study the component composition and intravarietal polymorphism of storage proteins of three soft and one hard varieties of spring wheat and their relationship with a complex of economically valuable traits. The studies were carried out in 2018–2020 by the department of genetics and immunity at the institute, in the conditions of the southeast of the Central Black Earth Region. In the course of the work, the identification of gliadin biotypes was carried out by electrophoresis in 6.5% polyacrylamide gel, the results of which revealed that the genome of the studied varieties contains: Chernozemnouralskaya 2 (5 biotypes), Voronezh 18 (5 biotypes), Voronezh 20 (4 biotypes) and a solid variety Voronezhskaya 13 (1 biotype). The selected biotypes were propagated for 3 years, analyzed and evaluated according to the indicators of the structural analysis of the elements of productivity and quality. Based on this, their economic and biological characteristics were given. It was found that biotypes 3 and 4 of the Chernozemnouralskaya variety 2, biotypes 1 and 2 of the Voronezhskaya 18 variety, biotypes 1 and 2 of the Voronezhskaya 20 variety proved to be the most productive relative to the standard during the study period. As for the quality indicators, as a result of the research the difference in quality of gliadin biotypes was revealed, which is important to take into account in breeding work to increase genetic diversity when creating high-quality varieties. The ones with the best quality were: biotype 1 of the Chernozemnouralskaya variety 2, biotypes 2 and 3 of the Voronezhskaya 18 variety. The best biotypes, distinguished by a complex of economically valuable traits, which differ from the initial variety, can be used in further breeding work for the accelerated creation of highly productive and high-quality spring wheat varieties.

Onion crops and their beneficial properties have been known for centuries. The biological characteristics of onion crops allow using their fresh green mass and bulbs almost all year round. Onion crops overwinter well, grow in early spring and are used at a time when no other crop yet pro-duces from open ground. One of the most common onion species today is the shallot (Allium ascalonicumL.). Varie-ties are needed for the successful introduction of the shal-lot into the production process or for cultivation in the gar-den. At present, 65 shallot varieties have been entered into the State Register of Breeding Achievements approved for use. Taking into account that the crop is diverse in its mor-phological structure, response to growing conditions and the ability to realize its biological potential, the plant breed-ers do a lot of work on selecting promising material and development of varieties for specific cultivation regions. The goal of this research was to study the shallot collection nursery regarding the main economically valuable traits under the conditions of the Moscow Region, to identify promising forms and develop new varieties on their basis. The study was conducted from 2017 through 2019 in the Moscow Region at the Federal Scientific Center of Vegeta-ble Crop Productionon the experimental plot of the Labora-tory of Onion Crop Breeding and Seed Production. The research targets were 80 shallot candidate varieties of var-ious ecological and geographical origins. In our study, the response of the candidate varieties to growing conditions varied significantly. The shallot is cultivated to obtain green onion and bulbs. Of all the varieties under the study, 10 varieties significantly out-yielded the standard variety Yashma (16.6 t ha) in terms of bulbs. The maximum yield of bulbs was obtained from the Zolotaya Zvezda variety -21.3 t ha; this variety exceeded the value of the standard by 46.4%. The findings obtained by studying the shallot collection material regarding the main economically valua-ble traits made it possible to identify the promising forms that may be used in further breeding work as genetic sources for developing new varieties.

Abstract During the growth season, the plants of rapeseed (Brassica napus L.) and brown mustard (Brassica juncea L.) are affected by various diseases: Fusarium blight, Verticillium blight, Alternaria blight, and others. The cultivation of rapeseed and mustard varieties resistant to diseases is a cost-effective and environmentally safe way to protect plants from diseases. The aim of the work was to evaluate the new breeding material of spring rapeseed and brown mustard for resistance to Fusarium blight in the form of tracheomycotic wilting of plants to continue breeding work to develop varieties of these crops. In 2017-2020, we carried out a phytopathological evaluation of new breeding samples of rapeseed and brown mustard for resistance to Fusarium blight. As a result, we selected a valuable breeding material of spring rapeseed and brown mustard resistant to Fusarium blight infection, which also exceeds the standard by economic characters. The productivity of the best selected samples is higher than the varieties Tavrion and Nika by 0.13-0.59 and 0.18-0.28 t/ha, respectively, the oil content of seeds – by 0.2-2.0 and 1.2-2.1 %, respectively. These samples will be used as donors of Fusarium blight resistance in breeding work during development of new varieties of spring rapeseed and brown mustard in the central zone of Krasnodar region.

Grain production stabilization is one of the main criteria for the development of agriculture in Russia. In this regard, in modern breeding, when developing varieties, considerable attention must be paid to their adaptability, i.e. parameters that ensure stable productivity in various growing conditions. The purpose of the current study was to estimate the spring barley samples according to the trait ‘yield’ for adaptability to the arid conditions of the Stavropol Territory and their further use in breeding work. The material for the study were 86 spring barley samples. In order to determine the stability, there was used a variance coefficient (V%) according to the method of B.A. Dospekhov (2014). The ecological adaptability (bi) and the environment index (Ij) were determined according to the method of S.A. Eberhart and W.A. Russell (1966) as presented by V.Z. Pakudin (1984). Homeostaticity (Hom) was assessed according to the method of V.V. Hangildin (1981). Stress resistance was determined according to the equations of A.A. Rosielle and J. Hamblin as presented by A.A. Goncharenko (2005). There were identified the highly productive samples ‘Mamlyuk’ (389 g/m2) and ‘Stirling’ (378 g/m2), possessing high responsiveness to improving environmental conditions (bi = 1.44–1.21), variability (V = 58.9–51,2%) and low stress resistance (Ymin – Ymax = -538–488). Such genotypes are capable of forming high yields in favorable conditions and may be of interest for breeding high-intensity varieties. The samples weakly responsive to changes in growing conditions were distinguished by high stability and homeostaticity according to the trait ‘yield’, namely ‘Nutans 74840’ (Hom = 2.88; V = 38.4%) and ‘Veles’ (Hom = 2.56; V = 38.5%), as well as the adaptable variety ‘Getman’ (Hom = 2.89; V = 40.6%). These samples are the most adaptive to the arid conditions of the Stavropol Territory and regions with similar cultivation conditions. They are recommended for use in breeding work.
