Neolithic Cultures

In the article, the questions of the chronology of the Neolithic cultures in the Volga-Kama basin are discussed. This discussion is based on the significant series of radiocarbon dates obtained on the different organic materials in several last years. The dates were obtained as tradition scintillation technique, as well as AMS method. There was established the different age of cultural complexes on the same site and the time of transition from early to later Neolithic was determined in the Northern Cis-Caspian region. The beginning of the early Neolithic and the final of the later stage were clarified. The Neo-Eneolithic period in the Lower Volga region has been verified. The frameworks of the Early Neolithic and coexistence of Mesolithic and Neolithic societies in the forest-steppe zone of the Volga region were considered. The low border of the Neolithic period in the forest zone of the Middle Volga region was established. In the Cis-Kama region, the chronological frameworks of the Kamskaya culture were determined and the chronological ratio between complexes of unornamented, pricked and combed ornamented ceramics were explained.

Points Of View

Purpose. The aim of the work is to analyze the chronology of Neolithic complexes containing flat-bottomed ceramics in the European part of Russia and the Ural-Siberian region, as well as an attempt to highlight patterns in the development of Neolithic Ural-Siberian cultural traditions amidst complexes with flat-bottomed ceramics of the Volga region. Results. Researches of Baraba culture of the early Neolithic of Western Siberia: Tartas-1, Ust-Tartas-1, Vengerovo-2, with radiocarbon dates 8th – 7th thousand BC made it possible to re-address the problem of complexes with flat-bottomed ceramics, especially in the Trans-Ural region and Western Siberia and, perhaps, to reconsider some established points of view. One of the first centers of the autochthonous origin of the Neolithic at the end of VIII – beginning of VII millennium BC is the Baraba cultural tradition of the West Siberian forest-steppe. Also, the autochthonous center for the origin of the Neolithic was the territory of the Northern Caspian region and the Lower Volga region in the first half of the 7th millennium BC. In the middle of the 7th millennium BC in the Volga-Urals region, due to direct migration of the population from the territory of the Aral-Caspian, an Elshan cultural tradition appears. In the second half of the 7th millennium BC the Neolithic of the Trans-Urals is being formed. Technology of Koshkino and Kozlovo cultural pottery traditions was most likely borrowed from the population of the Aral-Caspian, relations with which have been established since the Mesolithic. Conclusion. The obtained results give grounds to identify several centers of origin of the Neolithic in the territories of European Russia, the Urals and Western Siberia with flat-bottomed ceramics at the end of 8th – first half of 7th millennium BC and round-bottom ceramics in the middle of the 7th millennium BC. The oldest among them are sites of the Baraba forest-steppe.

Traits For Breeding

The work was carried out in 2018-2019 in the forest-steppe zone of Samara region. The purpose of the research is to conduct study samples of collection nursery of various ecological and geographical origins and identify new sources of economically valuable traits for breeding in the forest – steppe of the Middle Volga region. The material for research was 352 collection samples of spring soft wheat, including 108 foreign varieties and hybrids and 244 domestic samples of breeding institutions of the Russian Federation. Meteorological conditions during the research years were quite severe, and vegetation took place in arid and acutely arid conditions (hydrothermal coefficient in 2018 – 0.51, in 2019 – 0.48, with a long-term value in the region of 0.73). The greatest variability over the years of research was observed in the indicators of grain yield of samples (Сv=23.9...27.5 %) and plants height (Сv=10.8...12.9 %). According to the research results, 30 new genetic sources of economically valuable traits of spring soft wheat were identified. Sources of precocity (period of shoots-earing 35...37 days): Uralskaya kukushka, Chelyaba rannyaya, Tyumenskaya 25, Lutescens 70, Odeta, Libertina, Chi Mai, Long Fu 7, M83-1551. Sources of short stems (plants height 40...45 cm): KWS Torridon, KWS Jetstream, Florens, Eleganza, Long Fu 13. Sources of consistently high productivity (grain yield 415...554 g/m2, and the yield increase over the standard 71...210 g/m2): Erythrospermum 4089, Grekum 5523, Lutescens 6029, Lutescens 6074/6-23, Lutescens 6102/1-32, Lutescens 6102/1-34 Erythrospermum 6517/24-1, Ekada 214, Burlak, Ulyanovskaya 105, Lebedushka, Saratovskaya 73. Sources of high protein content (15.4...16.7 %) and gluten (36.0...42.0 %) in grain: Erythrospermum 3898, Erythrospermum 4112, Erythrospermum 4171, Erythrospermum 5289

The work presents the results of studies for 2017-2019, aimed at developing methods for increasing the productivity of sunflower hybrids cultivated according to the Clearfield system when using the microfertilizing mixture Agromineral in the forest-steppe zone of Middle Volga region. The results of the studies showed that the safety of plants at the time of harvesting is up to 91.8%; the maximum safety is achieved when processing crops by vegetation with Agromineral microfertilizing mixture at a dose of 3 l/ha. The leaf area increased until the budding phase, reaching a maximum of 99.2 thousand m2/ha, on a mid-season hybrid when processing crops with a dose of 3 l/ha, and then, due to drying of the lower leaves, it begins to decrease to the phase of the onset of flowering to 37.8 ... 57.9 thousand m2/ha. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8N477KLDM - 4.781 million m2/ha days. The use of fertilizers and micronutrient mixtures increases its value and, as a result, increases productivity by 9.09 ... 9.36 kg/ha with an absolute indicator of 27.2 ... 33.2 kg/ha.

During the Neolithic period, several ceramic traditions were developed on the territory of the middle Volga forest: unornamented, pin-pointed, combed, and pit-combed. The problem of their chronological correlation is very relevant at this stage of study. Currently, 29 radiocarbon dates have been obtained from Neolithic materials from 10 sites in the region. The presented work is devoted to their analysis. The Neolithization of the Mari Volga region is associated with the emergence of carriers of the tradition of making unornamented ware at the turn of the 7th-6th millennium BC. Starting from the middle of the 6th millennium BC. In the region, the tradition of ornamentation of ceramics with pin-pointed is spreading, which coexists with non-decorated dishes. With the beginning of the 5th millennium BC. the penetration of representatives of the Kama culture and pit-comb ceramics into the forest Middle Volga region may be related. Also radiocarbon dates allow confirming the coexistence at the beginning of the 5th millennium BC. in the region of all the ceramic traditions presented in the Neolithic period. At the same time, the time of extinction of the indicated Neolithic ceramic traditions is associated with the middle – third quarter of the 5th millennium BC.

The results of the study of 250 collection samples of spring soft wheat of various ecological and geographical groups are presented in order to identify the source material that combines optimal plant height and high productivity for the conditions of the forest-steppe zone of the Middle Volga region. The work was carried out in 2017–2020 in the Samara region. The study and evaluation of samples was carried out according to the Methodology of the state variety testing and the methodological recommendations of the VIR. The average height of plants in the samples over the years of research varied within 68.5-109.2 cm, the coefficient of variation of the trait was 11.86-13.72 %. The presence of a positive average and weak correlation between the yield and plant height, regardless of the moisture conditions of the year (r = 0.15-0.47), was revealed. A strong positive relationship was observed between the height of the samples and the following weather factors: precipitation in June (r = 0.94), precipitation during the growing season (r = 0.87), hydrothermal coefficient of June (r = 0.93), hydrothermal coefficient for the growing season (r = 0.83). The highest grain yield was formed by samples from the group of undersized and medium-grown, on average 416 and 428 g/m2, respectively. A number of highly productive varieties were identified: 3 medium-grown samples (105 cm) with a yield of 419.7-435.7 g/m2 and 21 undersized samples (85-102 cm) with an average grain yield of 485.0-585.7 g/m2. Dwarf specimens sample a stable manifestation of short-stemmed growth over the years and high resistance to lodging were noted. According to the research results, it was found that the optimal height of plants for the forest-steppe zone of the Middle Volga region is in the range of 85-105 cm. The selected undersized and medium-grown samples with high grain yield and dwarf samples with high resistance to lodging are recommended for use in breeding programs of the region and places with similar conditions.

The paper summarizes all currently known source data on the Neolithic Mahanjar culture in the forest-steppe Tobol region. Both scattered archival data - materials from Ubagan 2,3,5, Ust-Suerka 4 and several others - and the results of new archaeological works on such settlements as Kochegarovo 1 and Tashkovo 1 are published, which allows a significant expansion of the periphery of the Mahanjar culture to the north boundaries of the forest-steppe zone of the Tobol region. The western boundary of the periphery requires further work. The author traced geographical dependence in the distribution of materials in the composition of monuments with other Neolithic cultures. Based on the available absolute dates and the fixation of some facts of ceramics stratification, conclusions are drawn about the coexistence of Mahanjar complexes in the Tobol region with carriers of early Neolithic - Kozlovskaya and Koshkinskaya - and Late Neolithic - Poludenskaya and Boborykinskaya ceramic traditions from the end of early Neolithic to the mid of late Neolithic. It is assumed that the spread of the Mahanjar culture in the forest-steppe zone proceeded by including its carriers among the local inhabitants through social ties. The inclusion of the Mahanjar antiquities of the forest-steppe Tobol region in the corpus of sources allows us to expand our understanding of cultural genesis and migrations at the end of the early Neolithic.
