RESEARCH OVERVIEW

Abstract

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.
