Late perennial ryegrass - diploid

  • Late diploid perennial ryegrass which was bred in Northern Ireland by AFBI and first officially listed in 2019.

  • Dundrod performs very well under both cutting and grazing management schemes although it best suited to silage production where its key feature is its excellent first cut yield, comparable with many much earlier heading varieties.

Species: Lolium Perenne

Officially listed in: England and Wales, Scotland

Heading dates: England & Wales 2nd June, Scotland REE 47

Ploidy: Diploid

Bred in: Northern Ireland

Most suited to: Any medium - long term grazing and / or cutting ley where spring growth is vital



Dundrod provides high quality forage from both silage and grazing management. Grazing D values and second cut silage are particularly good and the high early spring growth displayed by Dundrod requires cutting at the correct growth stage to ensure quality is maximised.


Other Attributes

Dundrod has excellent Mildew resistance (7.5) and Crown Rust Resistance (7.8) as well as excellent ground cover scores.

Being a diploid, you should expect an average of 600,000 seeds per kilogram and a slightly more prostrate growth habit. Dundrod therefore brings ground cover and a higher plant population than tetraploid counterparts to mixtures.


Before recommendation, Dundrod has been extensively trialled across over 10 locations in the United Kingdom to gather data on its performance in multiple climatic conditions.

Dundrod 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.



DESCRIPTION: Dark green, densely or loosely tufted. Folded shoot and leaves.

FLOWERING HEAD: Flattened spike with the spikelets arranged alternately on opposite sides of the stem. The spikelets are stalkless with the narrow, rounded face fitting against the stem.

LEAF BLADE: Ribbed on upper surface, smooth and shiny underside. Red at base of stem.

AURICLES & LIGULE: Auricles are usually well developed, up to 1/12 of an inch (2 mm) long, or are sometimes lacking.
