Diversity, Distribution, and Phytocenology of the Genus Aegilops L. (Poaceae) in Uzbekistan

This study presents information on the diversity and phytocenology of the genus Aegilops L. in Uzbekistan. Our research was conducted in 2021-2024, with the results of analyzing literary sources, herbarium specimens, and data collected during field research. More than 600 herbarium specimens collected from the territory of Uzbekistan, stored in the herbarium funds of Tashkent (TASH), Moscow (MW), St. Petersburg (LE), and Almaty (AA) were analyzed for 5 species of the genus. Species diversity is presented by distribution in Uzbekistan's botanical and geographical regions. In research to date, as well as in major monographs, A. tauschi is not found in the flora of Uzbekistan. The fields in which the species is distributed also confirm our opinion. In the course of studies, about 20 distribution points were identified based on 3 growth points in the flora of the species as well as herbarium data. The genus Aegilops L. is considered to be closely related to wheat both ecologically and genetically, as they belong to the same natural polyploid series. The diploid, tetraploid, and hexaploid species of the genus Aegilops can be crossed with wheat, resulting in stable hybrids. Representatives of the category are of high economic importance, and natural samples are also widely used in agricultural sectors. It is representatives of the category that are resistant to various factors (drought, sudden warming or cooling of the Air, various environmental factors) that are very important for the sharply continental environmental conditions of our republic. Data on the distribution, phytocenology, and current status of the five species of the Aegilops L. genus are used for monitoring the species and maintaining vascular plant cadastres. Natural population areas serve as primary sources for selection and genetic research. The results obtained are recommended for future editions of the monograph
