ONE50
Proven on farm New Zealand wide
- Heading Date Late (+20)
- Ploidy Diploid
- Endophyte AR37, AR1, Low Endophyte
- Rust Tolerance Very High
- Perenniality Perennial
ONE50 is a late heading diploid perennial ryegrass of medium leaf and tiller size. It is NZ's largest selling perennial ryegrass for 5 reasons..
- Outstanding summer, autumn and winter growth particularly with AR37
- Excellent spring quality and summer leafiness
- Excellent use of summer irrigation or natural rainfall
- Proven persistent option and available in AR37, AR1 and LE endophyte options
- One of the most widely tested ryegrasses nationwide
ONE50 is a cross of elite New Zealand genetics and genetics of north-west Spanish origin, producing a cultivar with exceptional leaf production through summer, and high drymatter production through autumn and winter. ONE50 has always demonstrated a stay green habit through dry summers, often obvious in trials at this time. These traits were also observed by Matthews et al., (2012).
Key tips
- Ideally hard graze in November (regardless of seed head presence) to maximise summer quality.
- Consider including Relish red clover to increase clover content, as Relish is more competitive and productive over time.
- ONE50 benefits from late autumn nitrogen as it helps maintain its winter strong activity and assists with early spring vigour.
Performance Data
Agricom values individual trials that are undertaken New Zealand wide and the data they provide. For us, while the results may have statistical limitations, they deliver invaluable information on the basis of the specific locations and conditions in which they are undertaken, especially from the experiences and anecdotal feedback received.
Multiple trial summaries offer a level of confidence that a result will be repeated. It is important to be aware that the number of trials a cultivar is summarised in relates to the confidence you can have that the data summary will not change with the addition of extra trials. Cultivars summarised from a least 8-10 trials are less likely to change than ones summarised from 3-4 trials.
ONE50 is one of the most trialled cultivars in the New Zealand National Forage Variety Trials (NFVT). It was initially released with AR1 endophyte and has been in 20 three year trials with this endophyte option. More recently ONE50 was released with the inclusion of the endophyte option AR37. This has been even more widely tested and to date has been in 25 trials. ONE50 has also been tested without endophyte (WE) five times.
This makes ONE50 one of the most widely tested ryegrasses (with a variety of endophyte options) nationwide. It also makes ONE50 an ideal pasture cultivar with which to judge the value of different endophyte options for drymatter production throughout the country. ONE50 shows strengths in late spring, summer, autumn and winter (Table 1). While ONE50 AR1 is a competitive endophyte option, ONE50 AR37 is providing advantages in drymatter production over ONE50 AR1, with particular significance in the autumn.

* It is not advisable to mix AR37 and AR1 varieties. AR1 is not recommended for areas where black beetle, porina or root aphid are common problem pests. Grass seed should be Superstrike® treated where Argentine stem weevil, black beetle or grass grub are a risk to seedlings. For more information on AR37 endophyte, visit ar37.co.nz. AR37 endophyte is not suitable for deer or horse pastures.
