Glenariff, an intermediate diploid perennial ryegrass bred by the Agri-Food and Biosciences Institute (AFBI) is the newest variety to be released from the Department of Agriculture For Rural Development (DARD) funded grass breeding programme at Loughgall. The variety will be commercialised in spring 2015 by Barenbrug UK Ltd.
This new variety, which has taken almost 15 years to develop, is a further addition to the extensive portfolio of high-performance grasses which have been bred by AFBI specifically for use on local farms.
For over 20 years the intermediate heading variety Glen was used very extensively in grass seeds mixtures, especially where there was a requirement to produce a very dense persistent sward which would reduce poaching. Glenariff has been developed as a replacement for Glen and is a very similar variety in terms of having a very leafy, dense growth habit. In plot trials at Loughgall, Glenariff has produced on average 6% more yield than Glen, with better spring growth. Another valuable characteristic of Glenariff is that it produces very few seed heads in mid- summer, resulting in palatable swards with excellent digestibility.
Ongoing Progress
When the grass breeding programme was set up at Loughgall over 60 years ago, the focus was primarily on producing higher yielding varieties. Analysis of data from trials which were maintained under the same management, over a 30 year period, has shown a gradual increase in production equivalent to an increase in grass yield of 0.4% per year. So this means that the best varieties, such as Glenariff, which are being commercialised now, are at least 4% higher yielding than the best available a decade ago. Further analysis of recent trials at Loughgall, indicates that yields are continuing to rise gradually, year after year.
Focusing on Quality
Variety Portfolio
The result of this concerted research effort is a portfolio of new varieties which are already giving great performance on local farms. These include Dunloy and Drumbo, as well as Clanrye and Seagoe which were launched at the Winter Fair in 2014. AFBI has further new varieties in the pipeline, which are being multiplied by Barenbrug UK at present. These include a new intermediate diploid variety Moira, and an exceptionally high yielding intermediate tetraploid Fintona. At an earlier stage of development are Glenarm, Caledon and Ramore, which are setting new standards for yield and quality in Recommended List Trials.
To the Future
Grass is the most important crop on farms in Northern Ireland and one of the most efficient ways of improving productivity from grass is to breed varieties which are well adapted to local farming conditions. Consequently, continued investment by DARD and Barenbrug in the AFBI Loughgall programme will ensure a steady supply of new varieties like Glenariff which can meet the ever changing demands of the grassland industry.
When choosing new varieties for use in Northern Ireland, AFBI advise farmers to consult the DARD Recommended List of Grass and Clover which is available to view here.
