Abstract: Karyotype analysis of three genotypes from two species of Poeae (Agrostis stolonifera and Lolium perenne) is reported. All the chromosomes were median and submedian centromeric, with satellites (SAT). The number of chromosomes in A. stolonifera (Putter) was 30 (2n), and in L. perenne (Premier, Focus) was 14 (2n). The karyotype formula was 2n=30=22m (2SAT)+2sm for Putter and the asymmetry index was 55.2%, (“2C” type), for Premier, was 2n=14=12m (2SAT)+2st and the asymmetry index 58.0%, (“2C” type), and for Focus, was 2n=6m (2SAT)+8sm, the asymmetry index 63.05%, (“2B” type).
