Late perennial ryegrass - tetraploid

  • Performs very well under both cutting and grazing management schemes making it a very flexible option and ideal for fields that are both cut and grazed

  • Excellent spring yields of highly digestible forage and also performs well late in the season too.

Species: Lolium Perenne

Officially listed in: Scotland

Heading dates: Scotland REE 49

Ploidy: Tetraploid

Bred in: Northern Ireland

Most suited to: Any medium - long term grazing ley which will be grazed out



Killylea provides high quality forage from both silage and grazing management. Grazing D values and first cut silage is particularly good. It is one of only 3 varieties in the late tetraploid group to show D Values higher than control at every recorded point.


Other Attributes

Being a tetraploid, you should expect an average of 290,000 seeds per kilogram and a slightly more upright growth habit. Killylea has ground cover scores typical of the tetraploid type and to encourage tillering, will benefit from grazing, particularly in the first 12 months after establishment.


Before official recommendation, Killylea has been trialled across multiple different sites in the United Kingdom to gather data on its performance in multiple climatic conditions.


Killylea was bred for Barenbrug UK at AFBI (Agri-Food & Bioscience Institute) in Northern Ireland. The variety was named after a small village in Northern Ireland.
