Integral Assessment of Species of the Genus Allium L. (Amaryllidaceae) in the Western Part of the Kyrgyz Alatau

This paper presents the results of the current present species composition of the genus <i>Allium</i> L. (Amaryllidaceae) of the western part of the Kyrgyz Alatau. The phylogeny, ploidy, and chorological data are presented, and a checklist of species of the genus <i>Allium</i> in the study area is compiled. The large subgenera of <i>Allium</i>, including <i>Melanocrommyum</i>, have been identified, reflecting their prevalence in the mountainous regions of Central Asia. Ploidy of some species (<i>A. artrosanguineum</i> and <i>A. turkestanicum</i>) of the genus Allium growing in the western part of the Kyrgyz Alatau were studied for the first time using flow cytometry methods. The nrITS sequencing was used to construct a phylogenetic tree including sequences from the NCBI database. The phylogenetic tree of species of the genus Allium of the Kyrgyz Alatau was compiled taking into account previously published data. The list of studied <i>Allium</i> species in the Kyrgyz Alatau is represented by 25 species, which include seven subgenera and 17 sections. Also, the nomenclature of onion species is brought to the modern understanding of some species names. Based on specimens of the genus <i>Allium</i> collected in the western part of the Kyrgyz Alatau, an integral assessment of the current species composition using molecular-genetic, cytometric, and traditional botanical methods was carried out.
