“…Sorghum crops are not demanding on soils; they can grow on all soils, except for waterlogged ones, including saline ones. They form high yields of grain and green mass without fertilization, but respond well to irrigation [10,11,12]. Seedlings, shoots, roots and leaves of sorghum-Sudanese hybrids secrete allelopathic compounds that suppress such weeds as foxtail, smooth and common marigold, common ragweed, common brambles, etc.…”

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.

Sorghum has valuable biological features and great potential for use. Grain sorghum is characterized with super adaptability, good resistance to air and soil droughts and high temperatures, therefore it can become one of the promising crops in crop rotations. The developed varieties should be early-maturing and large-kernelled. The current paper has presented the study results of the collection nursery of grain sorghum samples of the world breeding. The trials were carried out in the laboratory for grain sorghum breeding and seed production of the FSBSI “Agricultural Research Center “Donskoy” in 2019–2021. According to the study results, there was established that, depending on the year, early-maturing forms made up 39.6–74.4 % of the studied collection. The samples ‘No.2-13’, ‘D577/19’, ‘F7 Pioner 88 x 412 Feterita rannyaya’ and the varieties ‘Kinelskoe 63’, ‘Kamyshinskoe 64’, ‘Kamyshinskoe 75’ were characterized by a short vegetation period (up to 90 days). In 2021, there were 44.8 % of the collection samples with ‘number of kernels per panicle’ from 1001 to 1500 pcs. When compared with the standard variety ‘Zernogradskoe 88’ (1532 pcs.), there were identified eight samples exceeding it in ‘kernel percentage per panicle’. There was found out that the largest part of the collection samples was characterized by a mean and large ‘1000-kernel weight’ (64.1–72.4 % and 16.8–25.5 %, respectively). A very large ‘1000-kernel weight’ (>40 g) through three years was established for the samples ‘Avans’, ‘Atlant’, ‘No.61–13’, ‘Spur Feterita’, ‘Redhull Feterita’, ‘Feterita’. There have been selected the forms with a complex of valuable traits for their further use in breeding work. The purpose of the current study was to research the collection material of various breeding according to such traits as ‘number of kernels per panicle’, ‘1000-kernel weight’, ‘length of a vegetation period’, which have a greater effect on grain sorghum productivity and to identify valuable sources due to these traits.

The current paper has presented the study results of the elements of cultivation technology (sowing date, sowing method, seeding rate) of grain sorghum in the southern part of the Rostov region. Field trials were carried out in 2018–2020. The object of research was the grain sorghum variety ‘Zernogradskoe 88’, included in the State List of Breeding Achievements for the North Caucasus region in 2013. According to the study results there was established that the lowest values of grain weight per plant and 1000-grain weight were formed with a seeding rate of 0.9 million of germinating seeds per ha.In the same variant of the trial, there was determined theworst plants’ preservation before harvesting. Sowing method had the greatest effect on plant density (69.5 %) and on 1000-grain weight (23.8 %); seeding ratehad the greatest effect on grain weight per plant (52.5 %). On average, through the years of study, there was obtained the maximum productivity of 4.14 and 4.12 t/ha with a seeding rate of 0.4 and 0.5 million of germinated seeds per ha, respectively. For grain sorghum, the sowing method with a row spacing of 0.15 and 0.30 m was the most acceptable, where there was yielded 3.70 and 3.65 t/ha. When sowing seeds in the 3rd decade of May (20–22 °C of warming up the soil at a seeding depth), there was identified a maximum productivity of sorghum grain with 3.92 t/ha. The greatest effect on productivity formation (41.6 %) was produced by the seeding rate, the share of the effect of the sowing date was 24.8 %, that of the sowing method was 3.6 %, weather conditions affected on 7.7 %.
