The object of the study was 152 specimens of Aegilops cylindrica Host. collected in 2024 from 17 districts in Bulgaria. DIVA-GIS approach was used to analyze the diversity. The descriptive analysis of the studied quantitative characteristics showed a wide range of variability among accessions. The Shannon diversity index exhibited a high level of diversity, with a maximum range of 1.109-2.0, 1.109-2.0, and 0.879-2.0, respectively, for the traits of plant height, spike length, and number of spikelets per spike. These findings indicate a notable responsiveness of these traits to the ecosystem. The grid maps generated for the diversity analysis of these characters indicated the occurrence of diverse accessions for plant height and for spike length from the municipality of Elin Pelin (district Sofia), and for number of spikelets per spike from the Kyustendil (district Kyustendil), Belitca and Bansko (district Blagoevgrad), Sevlievo (district Gabrovo), Karlovo (district Plovdiv), Mineralni bani (district Haskovo) and Elin Pelin (district Sofia) municipalities. The study would facilitate more effective management and utilization of Aegilops cilindrica Host. in the country.
