Status Codes:

  • 'Bold Type' - Varieties that have been tested in at least 5 separate trials and found to maintain very high performance levels (designated as Highly Recommended below)
  • 'Plain Type' - Varieties that may have been performing but have as yet completed less than 5 separate trials (designated as Fully Recommended below)
  • - Varieties which have consistently performed well in 5 or more trials but not with quite as high a performance as the 'Bold Type' varieties (also designated as Fully Recommended below)
  • (S) - Varieties recommended for a specific use as detailed in the text
  • (P) - Varieties which, as yet, have completed only 3 trials and are provisionally recommended pending further data (Seed may be in short supply)
  • (O) - Varieties which are becoming outclassed

Note: Varieties in bold text are in the most highly recommended classification.

Variety Descriptions

Variety descriptions are in alphabetical order. Information is also given on the breeder and on the name of the agent.

Barmultra II (T)
Barenbrug BV (NL) ; Bar
  • This recommendation is for a variety with first and second cut yields similar to Meribel but with a higher early spring growth and an exceptionally high first silage cut. The sward density is typical of a tetraploid variety.
Dorike(T)
Euro Grass (D); BSH
  • Among the highest yielding ,Plain-type, varieties for first and second year total silage yields, it has an exceptional first cut silage yield and an open sward density typical of a tetraploid Italian ryegrass.
Fox
Limagrain (FR); DLF
  • This variety is one of tithe highest performing diploid varieties in the ,Plain-type, classification. Its spring growth and density are similar to the best of the other ,Plain-types,, but with a notably high first cut silage yield and high total annual yields in both years.
Hunter (T)
Euro Grass (D); DLF
  • Good spring grazing and first and second year yields typical of other tetraploids, it also has a high sward density for a tetraploid variety.
Ligrande
(O)
Euro Grass (D); EG
  • This diploid variety has a very high first cut performance and creates a similar sward structure to most other recommended varieties, but its below average annual yield performances in both harvest years now means it is becoming outclassed.
Litonio (T)
Euro Grass (D); EG
  • This variety has a first year yield, plus a first silage cut similar to the ,Bold-Types, and is very dense for a tetraploid. Its other performance figures are more typical of the performance levels of the other ,Plain-Type, varieties.
Meribel
D.v.P. (B) ; DLF
  • ,One of the more dense Italian ryegrasses with a high yield ranking in both harvest years. Seasonal production is distributed more towards the latter part of the growing season.
Meryl
D.v.P. (B) ; EG
  • Produces very high first harvest year and second harvest year total annual yield results, plus very good spring yields, followed by a consistently high performance throughout the year, from swards of a good density.
