The paper is exploring the problem of the vital rate data in the Lower Volga region during the famine of 1932-1933. Despite the ample quantity of papers presenting this problem the estimations and indicators differ even in the papers of the same authors and valuation methods are not always reliable. The birth rate of the Lower Volga region was 76223 while the mortality was 184570 during the 1933 famine peak by our estimate. However, there are no vital rate data on the Kalmykia in the central statistical administration archives and the registration of 15,2 thousand deaths were not ascertained identically. The real losses from the famine of 1932-1933 in the Lower Volga region (excluding Kalmykia) are estimated at 175 thousand maximum and birth rate losses are 147 thousand in 1932-1934. The mortality of the Lower Volga region had clear geographical distribution and location. The high mortality regions were allocated on the Volga Upland and abutting the Oka-Don plain eastern frontier and on the Medium Syrt frontier in Saratov Krai. The allocation of high mortality regions to the Volga River is interpreted as associating with regions containing major cities and towns with high mortality neighborhoods to the Volga. Stalingrad Krai is defined as a region with lower mortality and gradual slow in its increase with a low peak displaced to July 1933. In 1933 the Lower Volga mortality dynamics was from north to south epidemic; whereas in the south there was time to assume the measures as opposed to northern regions. Some Lower Volga regions in 1933 were characterized by a catastrophic low birth rate and high mortality and at the same time by high birth rate and low mortality and positive vital rate data. The distribution of high mortality regions was determined by the character of local authorities activities and local conditions including geographical description (orthometric height), that requires background study.

Relevance. Modern agricultural production requires the creation of varieties that combine high productivity, quality, and adaptability. Taking into account the development trends of modern agriculture towards multiplicity, it is necessary to improve and expand the assortment, helping to meet the needs of both large and small producers of agricultural products. Due to the lack of material and human resources in the agricultural sector, there is a clear need for varieties and hybrids adapted to industrial cultivation and storage technologies. Existing zoned varieties of root chicory have a root crop length of 40 cm or more, and the soils of the area of cycoroseeding are mainly heavy in mechanical composition, where the use of digging devices to such a depth is impossible. Production requires varieties with a short root crop, which has the main mass concentrated in the upper part.Methods. The purpose of this work is to identify valuable genotypes in the soil and climate conditions of the non-Chernozem zone of the Russian Federation among the variety of varieties of chicory root of different ecological and geographical origin for use in the creation of the source material of selection by inter-port crosses.Results. When creating the source material for the selection of root chicory by the method of intervarietal crosses, one of the parents should choose local intrazonal varieties adapted to the soil and climatic conditions of the zone (Yaroslavsky, Gavrilov-Yamsky), and the second – off-zonal varieties with economically valuable qualities (short root crop, high yields and chemical-technological indicators, resistance to root rot) and donors of these traits (Kharpachi, Sleszka, BilogorkaOS-2, BilogorkaOS-3, Rexor, Wixor, Luxor).

This article is devoted to the Achaemenid cylinder seal, representing a fight of the Persian hero with two lions, from the princely burial in Kosika in the Lower Volga region dated to the third quarter of the 1st century BC. The analysis has shown that the seal is dated to the 5th century BC, more likely to its first half. There is a good chance that it could be carved in a peripheral workshop in Mesopotamia or in Syria. The seal, made of a high quality-material at the high level, represents a complicated and in certain aspects very rare composition, clearly standing out in the context of the Achaemenid glyptics. At least 400 years passed between the time the seal had been carved and its use as part of the burial inventory in Kosika. It is hardly to suggest that the seal belonged to nomads all this time, especially since the finds of the Achaemenid seals in the nomadic burials in Eurasia of the 5th–4th centuries BC are extremely rare, unlike their finds in the necropoleis of the Bosporan Kingdom. The Achaemenid seal from Kosika along with a Kassite cylinder seal found in the same burial belongs to the circle of the Western Asian and Near Eastern seals of the mid-2nd — mid-1st millennium BC which were found also in the burials of Sarmatian elite of the 1st century BC — early 2nd century AD in the Bug, the Don and the Kuban regions. They probably fell into the hands of the nomads during robbery of sanctuaries at Transcaucasia.

The results of studies of economically valuable traits of various varieties and new lines of winter wheat are presented. The studies were carried out on the experimental field of the Saratov State Agrarian University, located in the Lower Volga region with a sharply continental climate on dark chestnut soil. A study of the collection of varieties and lines of winter soft wheat made it possible to identify samples that are most suitable for economically valuable traits in the arid conditions of the Lower Volga Region and are highly adaptable. The largest grain yield was formed by the line  SP-108 (4.54 t / ha) and such varieties as Levoberezhnaya 3  (4.28 t / ha), Stanichnaya (4.19 t / ha), Gubernya (4.11 t / ha), Agra (4.04 t / ha), and Novoershovskaya (4.03 t / ha). Most of these varieties and lines were created by scientists from local breeding centers (Research Institute of Agriculture for  the South-East Region,  the Ershov Experimental Station and the Saratov State Agrarian University). The high content of raw gluten in the grain was revealed in the varieties: Levoberezhnaya 3 (35.3%), Aelita (34.7%), Patriarch (34.6%), Dzhangal (34.3%), Lutescens 72 (34.3% ), Zernogradka 9 (34.2%), Yunona (33.8%), Yesaul (33.7%); lines SP-137 (33.7%) and SP-110 (34.9%). The best indicators of IDK were found in such varieties as Levoberezhnaya 3 (67.8 units), Dzhangal (69.4 units), Aelita (73.7 units), lines SP-137 (69.0 units) and SP-110 (71.2 units). The noted varieties and lines of winter wheat are recommended for further breeding in the direction of increasing drought tolerance, adaptability and productivity of the crop in the arid zone of the Lower Volga Region. The SP-108 line (SGAU 11/2019) allocated for high productivity potential was transferred to the state variety test under the name Elegya (Stepnaya 19).
