The diversity of the varietal composition of sorghum crops necessitates a careful approach in the selection of varieties. This is especially important for the North Caucasus region, which is characterized by contrasting natural and climatic conditions. The purpose of the current study was to analyze the existing varietal range of grain, sweet, grass sorghum, to identify varieties recommended for cultivation in the North Caucasus region. The work on the development of sorghum crops was carried out at the Federal State Budgetary Scientific Institution “ARC “Donskoy” in accordance with the Methodology of the State Commission for Variety Testing of Agricultural Crops. There has been found that since 2013 20 grain sorghum varieties and hybrids of Russian originators (7 sugar sorghum varieties, 6 Sudan grass varieties, 7 sorghum-Sudan hybrids) have been approved for cultivation in the North Caucasus region of the Russian Federation. Since 2013 2 grain sorghum varieties, 2 sweet and Sudan grass varieties, 1 sorghum-Sudan hybrid have been developed and introduced into the Register at ARC “Donskoy”. There have been developed grain sorghum varieties ‘Zernogradskoye 88’, ‘Esaul’ which are distinguished by high grain productivity of 5.0–6.2 t/ha and have been recommended for use for feed and food purposes. Sweet sorghum varieties ‘Feniks’ and ‘Yuzhnoe’ have been characterized by a large productivity of green mass for silage (37–45 t/ha) and good feed qualities, which allows them to be used for silage production. Sudan grass varieties ‘Alisa’ and ‘Gratsiya’ have made it possible to obtain 2 cuttings of high-quality green fodder (39–44 t/ha) and hay (12.0–13.2 t/ha). The sorghum-Sudan hybrid ‘Dobrynya F1’ has 55–61 t/ha of green mass for two cuttings and could be recommended for use for green fodder, hay, silage.","PeriodicalId":33209,"journal":{"name":"Zernovoe khoziaistvo Rossii","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48528861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was developed a new spring barley variety ‘Rafael’ based on the Governmental task of the Federal State Budgetary Scientific Institution “Federal Research Center “Nemchinovka”, (FRC “Nemchinovka” (Moscow Region)) No. 0608-2019-0011 and the Institute of Seed Production and Agrotechnologies, a branch of the FSBSI “Federal Research Agro-engineering Center VIM” (ISPA, a branch of FSBSI FRAEC VIM (Ryazan region)) No. 0581-2019-0021. In 2020–2021 the variety was tested in the State Variety Testing. In 2022, the variety was included in the State List of Breeding Achievements of the Russian Federation and approved for use in the Central (3) and Volga-Vyatka (4) regions. The code of the variety is 8057530. There was received the patent No. 12254. Breeding number 35/1-09 h 662 was obtained when crossing the lodging-resistant variety ‘Ksanadu’ and the breeding lines 27/13-78 h 34 (‘Moskovsky 121 x Highproli’), identified from the genetic collection according to a complex resistance to helminthosporiasis of barley and soil drought. The analysis of long-term data (2014–2019) has shown that under various agrometeorological conditions of the environmental trials, the variety was characterized by improved productivity in comparison with the standard variety ‘Yaromir ‘and varieties of earlier breeding. In the experimental crop rotation FRC “Nemchinovka” exceeded the mean value of productivity on 0.44 t/ha, the productivity increase was on 0.68 t/ha more than that of the standard variety, and on 1.08 t/ha more than that of the parental variety ‘Ksanadu’. In the fields, the ISPA, a branch of FSBSI FRAEC VIM exceeded the standard variety on 0.09 t/ha, providing a mean productivity of 6.85 t/ha. The maximum value of the indicator of the variety stability level (PSSS = 141.6%) has characterized a high degree of variety adaptation to various environmental conditions. The economic efficiency calculation has shown an increased profitability of the new variety on 17.0–20.8% compared to the widespread varieties.

In addition to the characteristics of the variety and environmental conditions, productivity is greatly influenced by a forecrop. The purpose of the current study was to determine the adaptive properties of winter barley varieties according to productivity and adaptability indicators in the conditions of the Lower Don. In order to study this issue, in 2020–2022 there was carried out a study to estimate the adaptability parameters of 20 winter barley varieties developed by the FSBSI “ARC “Donskoy” according to various forecrops (black fallow, peas, sunflower). The plot area was 10 m2, with 4 repetitions and seeding rate of 450 germ.seed/m2. In order to determine indicators of homeostaticity (Hom), breeding value (Sc), stress resistance (Ymin–Ymax) and genetic flexibility ((Ymax+Ymin)/2), coefficient of responsiveness to favorable growing conditions (Kp) and index of variety stability level (VSL) there were applied the methods of V.

The conducted analysis has shown that on average over the years of study for all forecrops, the largest productivity was given by such varieties as ‘Marusya’, ‘Step’, ‘Pallidum 2100’. Also, for all forecrops, there have been identified the varieties characterized with high parameters of environmental adaptability and stability. The stable varieties were ‘Parallelum 2016’ and ‘Parallelum 2017’, which could be recommended for use in the breeding process as sources of high stress resistance, genotype value, and low variability of productivity.

On the experimental basis of the Samara Research Institute of Agriculture, there were studied grain quality indicators of hulled and hulles barley varieties of the Competitive Variety Testing in 2019–2021. There has been established a high-protein group of varieties, such as ‘Orlan’, ‘Bezenchuksky 2’, ‘Lun’, ‘Streletsky golozerny’ and ‘Omsky golozerny 1’ with 14.9–16.8 % of protein. The largest ‘1000-grain weight’ (43.7–44.1 g) and low activity of α-amylase in grain (352–421 c of ‘falling number’) over the years of study was established among the hulled barley varieties of this group. Barley varieties with such qualitative traits could be widely used in the food industry and feed production. There has been noted that hulles barley varieties with a high protein percentage (16.8 %), the absence of hulls and low amylolytic activity (471 c), when adapting to growing conditions, will improve not only the quality of cereals, grain fodder, but can also be used for baking purposes.

The development of such grain crop makes it possible to apply new technological methods and technical means to realize its potential. It is also necessary to establish the applicability of existing mechanization means in its cultivation in various natural and climatic zones of the Russian Federation, where it is possible to obtain and analyze data on its physical, mechanical and biological characteristics. Despite a big breakthrough in the development of trititrigia (it was included in the State List of Breeding Achievements in 2019), there are few scientific works devoted to it and there is not enough information about it, or it is contradictory, fragmentary, and it is almost impossible to meet such grain crop in the fields. In this regard, the purpose of the current work was to obtain statistically reliable information on the value of the force of kernel separation from a trititrigia ear of the variety ‘Pamyati Lyubimovoy’ in the dead-rape stage.
