Key words: wild relatives of cultivated plants, forms of existence of wild
relatives of cultivated plants, weeds, cultivated plants, cultivated plants, etc.
Introduction: Our country has innumerable plant resources and many of them
have not yet been touched by the hand of a breeder. When creating new varieties,
breeders are increasingly turning to wild forms of one or another species.
Wild relatives of cultivated plants (WRCP)are carriers of such biological
properties as resistance to extreme environmental factors (high and low temperatures,
droughts, salinity, flooding, etc.), as well as to diseases, pests, etc. Therefore, further
progress in breeding We cannot imagine without the comprehensive and complete
use of wild relatives of cultivated plants.
Due to the fact that the genetic wealth of the planet is under threat of rapid
decline, the World Food and Agriculture Association at the UN (FAS) raised the
issue of organizing its conservation in territories that coincide with the Vavilov foci
of origin of cultivated plants. But this does not mean that it is necessary to protect this
or that hearth as a whole. It is advisable, in our opinion, to determine the places of the
highest concentration of wild relatives of cultivated plants inside the focus, in which
to carry out the conservation of the gene pool.

focus, in which to carry out the conservation of the gene pool.
Therefore, we based our research on an in-depth study of Karakalpakstan and
Khorezm, which N. I. Vavilov attributed to the Central Asian origin of cultivated
plants (N. A. Vavilov, 1935).
The nature of most of the Republic of Karakalpakstan is represented by the
Kyzylkum desert, the Ustyurt plateau and the Amu Darya Delta, which are replaced
by relatively wide valleys, and the plains in the North turn into the vast plains of
Kazakhstan.
The Republic of Karakalpakstan has certain climatic, edaphic conditions and
associated vegetation types.
Geographic analysis of wild relatives of cultivated plants of the Karakalpakstan
focus shows that they are widespread in various ecological-geographical regions and
types of vegetation associated with different reliefs, therefore, it is necessary to give a
brief overview of the vegetation of the Karakalpakstan focus.
