Notizen: Abstract Giemsa C-banding patterns of the grassesFestuca rubra (2n = 6x = 42),Vulpia fasciculata (2n = 4x = 28) and their wild F1 hybrid ×Festulpia hubbardii (2n = 5x = 35) show marked differences between the chromosomes of the two parents that enable unequivocal identification ofFestuca andVulpia chromosomes in the hybrid. Moreover, meiotic banding patterns reveal that both homogenetic (Festuca-Festuca andVulpia-Vulpia) and heterogenetic (Festuca-Vulpia) pairing occurs in the F1. The significance of this in relation to the formation of backcrosses to theFestuca parent and to the evolution of theFestuca polyploid complex in general is discussed.
