Abstract The nuclear genome sizes of 59 species from 33 genera the Poaceae subfamily Pooideae were investigated by flow cytometry. This is characterized a wide range holoploid (2C values) and monoploid (1Cx mean chromosome sizes, including both highest some lowest values entire grass family. For example, tribe Brachypodieae has smallest genomes chromosomes, followed majority Stipeae individual representatives tribes Ampelodesmeae, Duthieeae Meliceae, which belong to phylogenetically ‘early-diverging’ lineages. Comparatively large found in Lygeeae Meliceae. ‘core Pooideae’ had largest subfamily, with greatest variation Aveneae, Festuceae Poeae. Bromeae especially Triticeae, includes wheat related crops, larger minimum compared other tribes. It appears that occurrence exclusively rather (> 3.4 pg/1Cx) chromosomes (MC ≥ 0.5 pg) restricted Triticeae. origin x = 7 12 lineages was apparently not an increase size, whereas fusion caused size. evolutionary aspects base number are discussed, new numbers presented, first polyploid (2 n 4 20) model plant Brachypodium distachyon s.s.
