Late perennial ryegrass - tetraploid

  • Late tetraploid perennial ryegrass which was bred in Northern Ireland by AFBI and first officially listed in 2020

  • 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
  • Gracehill’s key feature is its excellent spring growth making it a great choice for swards for early turnout or silage production

Species: Lolium Perenne

Officially listed in: England, Wales & Scotland

Heading dates: England & Wales 1st June, Scotland REE 47

Ploidy: Tetraploid

Bred in: Northern Ireland

Most suited to: Any medium - long term ley which will be grazed or cut



Gracehill provides high quality forage from both silage and grazing management and the high early spring growth displayed by Gracehill will require careful management to maximise D value at first cut.


Other Attributes

Gracehill has a strong all round disease resistance profile making it a variety than can be used across all regions of England and Wales. Crown rust resistance is 7.9, Drechlera resistance 8.7 and Mildew resistance 8.0.

Being a tetraploid, you should expect an average of 290,000 seeds per kilogram and a slightly more upright growth habit. Gracehill 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, Gracehill has been extensively trialled across 17 different site in the United Kingdom and Ireland to gather data on its performance in multiple climatic conditions.

Gracehill was bred in Northern Ireland at the Agri-Food and Biosciences Institute (AFBI) by the now retired grass breeder David Johnston. The variety was named after a village just west of Ballymena in Country Antrim which was originally founded in 1765 by Moravians.
