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

This paper presents the results of the modern species composition of the genus Allium L. (Amaryllidaceae) of the western part of the Kyrgyz Alatau. The data on phylogeny, ploidy, chorological data are presented and a modern prospectus of species of the genus Allium in the study area is compiled. Large subgenera of Allium and Melanocrommyum are revealed, which proves the general regularity for mountainous regions of Central Asia. Ploidy of some species (A. artrosanguineum and A. turkestanicum) 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. In the course of field studies and literature data, the list of studied Allium species in the Kyrgyz Alatau is represented by 25 species, which include 7 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 Allium 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.
