The Family Poaceae is on the first place in Russia as to chromosome studies. As continuation of
chromosome studies on the Poaceae, the new data on chromosome numbers in 20 species from Russia
are presented. The geographic area, ecology, basic chromosome numbers as well as investigation
status of these species are shown. First chromosome data are obtained for 10 species – Bromopsis
alpina, B. probatovae, B. simaczevae, Elymus ircutensis, E. komarovii, E. uralensis, E. viridiglumis,
Festuca amurensis, Leymus jenisseiensis, Neomolinia koryoensis, new chromosome numbers – in
Elymus schrenkianus and Poa pseudoattenuata; the last species that has variable ploidy, shows a new,
decaploid cytotype (10 x) in continental part of its geographical range. Deschampsia gulariantzii is
reported and studied for the first time from Sakhalin, Macrohystrix komarovii firstly studied from
Khabarovskii Krai, Poa tanfiljewii – from Republic of Buryatia. Agrostis mongolica from West Siberia is
studied for the first time in Russia. The significance of the data obtained is discussed.
