The results of ecological and cenotic analysis of wild relatives of cultivated plants (DRC) of the Republic of Karakalpakstan and Khorezm are presented. Based on the classification of P. V. Kulikov (2005), a system was developed, where 8 ecologo-cenotic groups of DSCS were identified, and the resulting groups were divided into 16 subgroups. Ecological-cenotic analysis showed that the DSCS of the Republic of Karakalpakstan and Khorezm are mainly plants of deserts and meadows (58.5%). However, a significant share (19.9%) is made up of species with a narrow ecological amplitude, confined to specific habitats: saline soils and coastal (coastal and coastal-meadow). Desert-tope species are among the most vulnerable, 12 of which need to be preserved also because 3 of them are endemic and one is a relict species, which, due to their adaptation to extreme environmental conditions, can contain valuable genetic information.

The N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) is working on replenishing seed and herbarium collections of cultivated plants and their wild relatives through collection missions in various regions of Russia. The collections are replenished with both live specimens (plantlets, runners, cuttings, bulbs, seeds, etc.), and with herbarium specimens of crop wild relatives (CWR). The Republic of Sakha (Yakutia) is characterized by a variety of natural conditions and resources, while many territories are difficult to reach by transport. Collection missions were carried out by VIR in the territory of Yakutia from 1972 to 1990. Field research in the territory of the republic is relevant to this day.In 2020, field research in the area of the projected bridge crossing over the Lena River near the city of Yakutsk resulted in collecting 18 samples of wild relatives of fruit, vegetable, essential oil, oil and fiber, forage legume, and cereals crops (live plants and seeds), as well as 45 CWR herbarium specimens. CWR (species of currants, onions, horseradish, water sorrel, tarragon wormwood, etc.) were found in floodplain habitats and on river banks, some were collected in ruderal biotopes, near settlements, less often in forest phytocenoses, and on steppe meadow slopes. All the samples were included in VIR collections. The phytocenoses from which CWR were collected, were comprehensively described.

The results of systematic review of wild relatives of cultivated plants (WRCP) of the Republic of Karakalpakstan and Khorezm are presented. In the flora of Karakalpakstan and Khorezm, 171 species of wild relatives of cultivated plants belonging to 117 genera and 39 families are recorded. The largest number of WRCP species is found in the Chenopodiaceae. Family, there are 11 general, 29 species in it, which is 9.44 and 16.9 %%, respectively. The family Poaceae has 25 species of wild relatives, concentrated in 20 genera (14.6% and 17.12%, respectively). The third place belongs to the Fabaceae family and Asteraceae: 15 (8.77%) and 13 (7.6%) species, respectively, belonging to 10 (8.56%) genera were recorded in it. Family - Brassicaceae - represented in the outbreak by 11 (9.44%) genera, in which 13 (7.6%) species are wild relatives of cultivated plants or are close to cultivated.

Studying wild relatives of cultivated plants in each specific region is an essential component in assessing the state of national plant genetic resources. This is especially true for the regions of the Russian Caucasus, with its tremendous diversity of plant species. This paper presents the results of exploring crop wild relatives (CWR) in natural plant communities of the Karachay-Cherkess Republic. The author conducted an inventory of CWR and analysis of their species composition in Karachay-Cherkessia. The CWR list includes 516 species belonging to 134 genera of 36 families; in this list, 449 species from 107 genera of 33 families are native to this region. The Dzheguta floristic district is the richest in CWR species diversity (391 species). There are 350 and 346 species in the Arkhyz and Uchkulan districts, respectively, and 301 species in the Cherkessk district. Species were ranked according to their agricultural value and economic importance: the 1st rank was assigned to 149 plant species, 2nd rank to 17, 3rd rank to 32, 4th rank to 97, and 5th rank to 222 species. In the context of their economic use, the species for feed (158) and food (136) purposes dominated over those for medicinal (60), melliferous (54), ornamental (53), industrial (51), and revegetation (5) applications. The list of priority conservation species was compiled for CWR of Karachay-Cherkessia according to the criteria of rarity and vulnerability, based on the analysis of the CWR species distribution over the studied area and their assessment for useful economic and biological traits. A map showing localities of these species within the Republic is presented, and recommendations are given for their effective conservation.
