Interspecific and intergeneric hybrids in herbage grasses

XIII. The breeding affinities ofFestuga Heterophylla
  • T. J. Jenkin
Article

Summary

  1. 1.

    Festuca heterophylla (2n = 28?) has given fully establishedF 1 hybrid progeny from crosses with:F. capillata (2n = 14),F. rubra (2n = 42?),Lolium perenne (2n = 14).

     
  2. 2.

    Embryos were produced whenL. loliaceum (2n = 14) was pollinated byF. heterophylla but the seeds failed to germinate.

     
  3. 3.

    Caryopses were produced but embryos could not be identified whenF. heterophylla was intercrossed with:F. pratensis (2n = 14),F. vaginata (?),F. arundinacea (2n = 42), but the seeds failed to germinate.

     
  4. 4.

    F. heterophylla, therefore, has some degree of breeding affinity with at least seven other district types in the generaFestuca andLolium, including both fine-leaved and broad-leaved fescues, and therefore provides another link between the fine-leaved fescue types and one another, between these types and the broad-leaved fescues, and between the generaFestuca andLolium.
