Estimation of genome size

Nuclear genome size was estimated by flow cytometer in several grass species, mainly from Festuca-Lolium complex.

  • diploid cultivar ‘Kolumbus’ (2n = 2x = 14) of F. pratensis
  • tetraploid cultivar ‘Patra’ (2n = 4x = 28) of F. pratensis
  • diploid cultivar ‘Prolog’ (2n = 2x = 14) of L. multiflorum
  • tetraploid cultivar ‘Lubina’ (2n = 4x = 28) of L. multiflorum
  • diploid cultivar ‘Handicap’ (2n = 2x = 14) of L. perenne
  • tetraploid cultivar ‘Korok’ (2n = 4x = 28) of L. perenne
  • hexaploid cultivar ‘Kora’ (2n = 6x = 42) of F. arundinacea
  • fine-leaf fescues (F. henriquesii, F.ampla ssp. ampla, F. ampla Hack. ssp. transtagana Hack, F. brigantina, F. summilusitana, F. rubra L. ssp. rubra, F. rubra L. ssp. pruinosa (Hack.) Piper, F. rubra L. ssp. litoralis (G. F. W. Meyer) Auquier, F.duriotagana var. barbata and F. paniculata ssp. multispiculata
