Variety Descriptions

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

AberAvon	IBERS (UK); BSH Its high annual grazing yield at a very high digestibility level and high sugar content reaches optimal production during early summer to autumn. Its high silage yields are enhanced by its high quality characteristic giving excellent 2-cut digestible yields from an erect open growth habit.
AberChoice (S)	IBERS (UK); BSH This variety delivers excellently high 2-cut digestible silage yields, driven by a very high second cut. Its total grazing yields are similarly excellent, providing high quantities of highly digestible grass from early summer. Its open growth makes it specifically recommended for use on drier ground or mixed with dense diploids.
AberDart (S)	IBERS (UK); BSH Specifically recommended for producing good annual grazing yields of very high quality grass at a high sugar content for a diploid. It has a similarly high grazing production ranking throughout the growing season and forms erect but dense swards.
AberGreen (P)	IBERS (UK); BSH This new provisional recommendation has very high grazing yields and an exceptionally high 2-cut digestible yield driven by a very high second cut.
AberMagic	IBERS (UK); BSH Capable of producing notably high grazing yields throughout the summer/autumn season at a high digestibility, high sugar level. It also delivers high digestible yields over the first two silage cuts and has an erect growth habit.
AberStar	IBERS (UK); BSH This variety has impressively high total grazing and silage yields, plus superb production across the main summer months and into the autumn, under both management systems.
AberZest (S)	IBERS (UK); BSH Produces very high total silage yields particularly in the first two cuts plus a high grazing yield and digestibility with excellent late summer and autumn growth. Specifically recommended for mixtures that balance its open growth habit.
Bahima 1 (P)	Cebeco Seeds BV (NL); DLF This provisional recommendation produces very high total silage yields, a high 2-cut digestible yield and has an excellent first cut silage yield, plus spring growth is high for an erect growing intermediate variety.
Betty (S)	Euro Grass (D); EG Produces high total annual silage yields with high second and if required third silage cuts. Total grazing yields, grass quality and the early summer growth are only moderate to low and hence it is specifically recommended for use in silage swards.
Boyne	DLF Trifolium (DK); DLF This variety has exceptionally high total and two-cut silage yields, which are driven by an impressively high first cut. Total grazing yields are also extremely high, most notably in spring, are of high quality and are delivered from dense growing swards.
Bree	Cebeco Seeds BV (NL); DLF Produces high annual grazing yields, especially in the main summer growing period; high total annual and 2-cut digestible silage yields, and has an erect though dense growth habit.
Cashel (O)	Teagasc (ROI) ; DLF Performs similarly under grazing or silage use, provides high second and third cut silage yields from dense swards but is now outclassed by most other recommended varieties.
Copeland (P)	DARD (UK) ; Bar A provisional recommendation with similarly high silage and grazing yields. It forms dense grazing swards that are very highly productive in spring and from late summer to the end of the growing season.
Denver	Advanta Seeds BV (NL); DLF Produces excellent 2-cut total and digestible silage yields. Grazing performance is best during the main summer growing period and forms swards of good density.
Donard	DARD (UK) ; DLF Very high total grazing and good silage yields, with excellent spring and autumn production and exceptional aftermath growth, from erect swards.
Drumbo	DARD (UK) ; Bar This variety provides impressively high 2-cut digestible silage yields and high total grazing yields of highly digestible grass. It also offers a high third silage cut, if required, and as a late variety has its highest seasonal grazing performance from early summer onwards.
Foxtrot	Limagrain Genetics (NL); DLF A high yielding diploid variety when grazed, with a high grazing digestibility, and is particularly productive during the main summer growth period. Produces very good 2-cut digestible silage yields and forms tall erect growing swards.
Gandalf	Advanta Seeds BV (NL); DLF High two-cut silage yields boosted by its second cut performance, plus good grazing production that is maintained through the summer from very dense grazing swards.
Genesis	Teagasc (ROI) ; DLF This variety provides extremely high total silage and total grazing yields, has the highest spring yields of all varieties as well as very high production after the second silage cut.
Gerrison	DLF Trifolium (DK); DLF This variety has high silage yields that deliver notably high two-cut digestible yields. Its total grazing yields are even higher, as its delivers very high production in spring and from late summer to the end of the growing season.
Glenveagh (P)	Teagasc (ROI) ; DLF This new provisional recommendation gives high 2-cut digestible silage yields, shows good digestibility from grazed swards that peak in production during the main summer periods, and maintains a high level of sward density.
January (S)	Teagasc (ROI) ; DLF Specifically recommended for its very high silage yields with a large early first cut followed by a high autumn or aftermath growth. It also has excellent spring grazing yields.
Kilrea	DARD (UK) ; Bar Although a late maturing member of the early group, it provides very high spring grazing yields and creates good grass quality from swards of a high grazing density. Silage productivity is notably high in the second and third cuts, followed by an impressive aftermath performance.
Kimber	Advanta Seeds BV (NL); DLF At the very late end of the early group, it produces high second cut silage yields. It will also deliver very high spring grazing yields and maintain a very high grazing grass quality for an early diploid.
Mateon 1	Cebeco Seeds BV (NL); DLF Produces high total silage yields that are at their greatest during the first two silage cuts. It also produces excellent quality grazing grass from dense swards, that peak in production during the main summer growing periods.
Moyola	DARD (UK) ; Bar This variety has similarly very high total silage and grazing yields. It has extremely high spring yields, excellent aftermath grazing and if required delivers a high third silage cut from erect growing swards.
Pastour	Limagrain Genetics (NL); DLF Forms erect swards and delivers high silage yields that become extremely high when digestible yield in the first two silage cuts is measured. Its high total annual grazing yields are strongest during the main summer growth period, which is typical of a late maturing variety.
Portstewart	DARD (UK) ; Bar Forms erect silage swards, produces a high 2-cut digestible yield, provides good total annual grazing yields distributed mostly in the main summer period with less production in Spring and autumn.
Solomon	Teagasc (ROI) ; DLF A variety with remarkably high 2-cut digestible yields that is still capable of a very high third cut, if required. Its high grazing yields comprise uncharacteristically high spring yields for its maturity, followed by a consistently strong performance to the end of the grazing season.
Spelga	DARD (UK) ; Bar An early member of the intermediate group with notably high silage yields, featuring a very high first cut performance and an erect growth habit, plus high grazing yields in spring and for later season grazing.
Twytop (S)	Advanta Seeds BV (NL); DLF This, the latest maturing diploid variety, is specifically recommended on account of its excellent grazing yields and superior summer production. Also very valuable for contributing to the second silage cutting cycle.
Tyrella	DARD (UK) ; Bar Has high total annual silage yields with an exceptional first cut silage yield for a late maturing variety and may benefit from earlier cutting to raise the 2-cut digestible yield. Its high annual grazing yields are distributed relatively evenly across the growing season and it has a sward density typical of a dual-purpose type variety.
