Chromosome numbers (CN) for 35 species and one hybrid in Poaceae from 9 genera: Beckmannia, Brachypodium, Bromopsis, Catabrosa, Elymus, Elytrigia, Festuca, Milium, Poa, from Russia are presented. For Bromopsis austrosibirica Peschkova, Deschampsia baicalensis Tzvelev, D. submutica (Trautv.) O.D. Nikif., Festuca chionobia T.V. Egorova et Sipliv., F. dahurica (St.-Yves) V.I. Krecz. et Bobrov, F. kolesnikovii Tzvelev, F. vylzaniae (E. Alexeev) Tzvelev, Poa khokhrjakovii Prob. and P. krasnoborovii Stepanov the CNs were revealed for the first time. The new CNs were obtained for Bromopsis heterophylla (Klokov) Holub, Deschampsia obensis Roshev., Elytrigia trichophora (Link) Nevski. Some species were studied first time: Elymus kamoji (Ohwi) S.L. Chen and Catabrosa minor (Bab.) Tzvelev – in Russia, P. glauca Vahl – in Amurskaya Oblast’, Festuca jacutica Drobow – in Khabarovskii Krai, Poa angustifolia L. – in the North Koryakia, Milium effusum L. and Deschampsia komarovii V.N. Vassil. – in Kamchatka Peninsula. From the Commander Islands the hybrid Poa alpigena (Blytt) Lindm. ? P. arctica R. Br. was studied. Besides, in the “tuft form” of Festuca rubra L., which is distributed along seacoast and islands of the Primorskii Krai, the CN was firstly revealed. F. chionobia obviously is the first pseudoviviparous species with the diploid CN (2n = 14).
