Complete immunological characteristics of the collection of hull-less barley in the conditions of the southern zone

Barley production in the Rostov region, as well as throughout Russia, has taken its niche in agricultural production. Winter barley attracts farmers’ attention with its unpretentiousness and high productivity. The relevance of immunology used in the production of barley varieties does not decrease over time. Yield losses due to various leaf diseases can be as high as 30–50 %. The most common pathogens in the region are powdery mildew and helminthosporium blotches. The most effective and efficient way to improve the resistance of new varieties is the use of artificial infectious backgrounds. Provocative and extreme conditions promote a selection of parental forms and breeding lines that are most resistant to pathogens. The current paper has presented the results of the estimation of winter barley breeding and collection material based on the FSBSI Agricultural Research Center «Donskoy». The purpose of the study was to identify winter barley varieties and lines which are stably resistant and tolerant to leaf-stem pathogens common in the Rostov region. About 250 samples are being estimated in the period from 2019 to 2021. Over the years of study, there have been identified such varieties and lines resistant to powdery mildew as ‘Bezosty 1954’ (RF), ‘Grand’ (RF), ‘Parallelum 1967’, etc. Resistance to heliminthosporium spotting was demonstrated by the varieties ‘Bezosty 1954’ (RF), ‘Grand’ (RF), ‘Rostovsky 908’ (RF), ‘Donskoy 11’ (RF) and the lines ‘Parallelum 1967’, ‘Parallelum 1974’, ‘Pallidum 1916’, ‘Pallidum 1970’, ‘Parallelum 1960’, ‘Parallelum 1911’, ‘Nutans 1895’ and others. There were also identified such varieties with resistance or tolerance to both pathogens as ‘Grand’ (RF), ‘Sekret’ (RF), ‘Fox 1’ (RF), ‘Marusya’ (RF), ‘Karisma’ (England) and the lines ‘Bezosty 1954’, ‘Parallelum 1967’, ‘Parallelum 1974’, ‘Parallelum 2015’, ‘Parallelum 2016’, ‘Parallelum 2017’. All presented varieties and lines are proposed for use in further breeding for immunity to the studied pathogens.

Abstract. The purpose. To study the effectiveness of a complex multicomponent organomineral fertilizer of prolonged action based on local man-made waste from the metallurgical industry and poultry farming and extracted sources of mineral nutrition for plants. Methods. The article presents data on the study of the effect of a new organomineral fertilizer on the growth, development and yield of spring barley. Phenological and biometric observations were carried out, yields were taken into account, and quality indicators of grain were determined: weight of 1000 seeds, nature and protein content. Results. It has been established that the use of an innovative mixed multicomponent organomineral fertilizer improves the growth and development of barley plants. So at doses of 60 and 90 kg of AD per 1 ha of nitrogen and phosphorus, the length of the plant stem increased to 6.78–6.84 cm, the number of grains per ear increased from 0.39 to 1.08 pcs. and their weight increased by 0.13–0.15 ha. The highest yield was obtained with NP (60) – 4.91 t/ha, which is significantly higher than the control variant. When applying the fertilizer, the grain quality indicators improved: the weight of 1000 seeds, the nature of the grain and the protein content in the grain. It is noted that the use of a new organomineral fertilizer at a dose of NP (60) increases the productivity and quality of products and is optimal for the cultivation of barley in the Middle Urals. Scientific novelty. For the first time in the Middle Urals, a new innovative product was created and tested – a combined, mixed multicomponent fertilizer for growing crops, application for a patent of the Russian Federation No. of the task number 122032200206-4.
