24 Seven Happe

Perennial ryegrass

Very late-heading diploid

24SevenHappe is a ryegrass-endophyte combination that will be released from DLF Seeds New Zealand plant breeders in March 2018, and is suited to all regions of New Zealand.  The novel endophyte Happe provides this grass with protection from black beetle, porina, Argentine stem weevil (ASW), pasture mealy bug and root aphid, without affecting animal production or health.

The production of 24Seven has been tested in several trials (4 completed, 10 current) across the country, in which 24Seven has never been beaten by other commercial cultivars.  It also has unusually strong cool-season growth for such a late heading date (see graph below).  24Seven therefore breaks the old dilemma created from late heading ryegrasses having less early-spring growth than mid-heading cultivars.

24Seven also produces stems and flower heads 24 days later than standard date cultivars, so it extends the period of high energy and protein pasture in late spring by almost one month.  Farmers (and their animals) can now "have their cake, and eat it too"!
