“…It has been established that per 1 mm of precipitation per 1 hectare of crops, grass sorghum forms up to 26 kg of dry matter, while spring cereals -6.3 ... 14.7 kg [3]. During a drought, corn leaves wither, sorghum leaves curl up until more favorable conditions occur [4][5][6]. Compared to corn, sorghum-Sudanese hybrids have a smaller leaf area, a more developed root system, a waxy surface of leaves, a large amount of carbohydrates in the cell sap, and a special structure of the stomatal apparatus, which helps to resist drought [5][6][7][8].…”

Sorghum-Sudanese hybrids, due to the heterosis effect, have not only increased productivity, but also uniformity, increased vitality, as well as resistance to various diseases and stress factors in comparison with parental forms. The purpose of the work: to characterize the new hybrid Dobrynya, created as a result of heterosis selection, according to the main morphological, biological, economically valuable indicators. The studies were carried out at the Federal State Budgetary Scientific Institution, Agrarian Research Center “Donskoy” (ARC “Donskoy”). The soil of the experimental plot is ordinary carbonate chernozem. The advantages of the hybrid include high foliage (13 leaves per plant) - 39-41% of the leaf mass of plants, good protrusion of the legs (30-35 cm), succulence, tillering, cold resistance. The duration of the period “sprouts-heading” on average for 2019-2022. was 55 days (mid-season), which is 5 days less than the standard. Sorghum-Sudanese hybrid Dobrynya is characterized by a high yield of green mass - 63 t/ha (in total for 2 cuttings) and dry matter - 13.0 t/ha, which is higher than the standard by 28.6 and 31.3%, respectively. -essentially. And in terms of the content of crude protein and the collection of digestible protein, it significantly exceeds it by 1.1% and 0.24 t/ha. According to the results of the assessment in natural conditions, Dobrynya is distinguished by high or practical resistance to loose smut and bacteriosis. The sorghum-Sudanese hybrid has been included in the State Register of Breeding Achievements since 2023 and is recommended for use for green fodder and silage in the Central Black Earth, North Caucasus and Lower Volga regions of Russia.

Abstract. Sweet sorghum in several large agricultural regions of the Russian Federation with unstable or insufficient moisture is becoming a real alternative to traditional feed grain crops. It has high adaptability and provides a stable green mass yield for silage. The purpose of the current work was to estimate and characterize promising sweet sorghum varieties developed by the ARC “Donskoy”. Methodology: the current study was carried out in the FSBSI “Agricultural Research Center “Donskoy” from 2020 to 2022. The soil of the experimental plot was ordinary calcareous heavy loamy blackearth (chernozem). The objects of research were 17 new varieties being studied in the nursery of the competitive variety testing. Scientific originality lies in the study of morphological, biochemical, and productive indicators of the new promising sweet sorghum varieties; in identifying among them the most adaptive ones to the conditions of insufficient (or unstable) moisture in the North Caucasus. Results. During the study there was found out that when selecting varieties according to economically valuable traits, it should be taken into account that the growing conditions have no effect only on a vegetation period and a number of leaves are practically, other traits can change significantly. According to green mass productivity, the most stable samples were ‘M’ (V = 2.7 %), ‘ZR-1/44’ (V = 7.3 %), ‘KL-12198/2’ (V = 8.2 %), ‘RS-124/ 19’ (V = 9.3 %), ‘Sakharnoe 105/3’ (V = 10.2 %). The analysis of quality and productivity indicators there were identified the new sweet sorghum varieties ‘Yuzhnoe’, ‘Amazanit 301’ and ‘Feniks’. The identified varieties have exceeded the standard one on 4–13 t/ha of green mass, on 2.9-–4.3 t/ha of dry matter, on 0.24–0.36 t/ha of digestible protein. The varieties ‘Feniks’ and ‘Yuzhnoe’, approved for use in the North Caucasus, the Central Blackearth and the Low-Volga regions of the Russian Federation, can be recommended for widespread introduction into agricultural production.
