Cynodon transvaalensis x Cynodon dactylon, Hybrid Green Couch Grass, Hybrid Bermuda Grass 'AGRD'

‘AGRD’ was selected by the breeder, Dr Warren Hunt, from a variant area of winter active turf (probably ‘Tifway’ or ‘Tifgreen’) on a Hong Kong Golf Course in Apr 1996. A selection of this material was imported through vegetative quarantine to New Zealand for evaluation. Following a favourable assessment of its potential as a warm-season turfgrass variety under New Zealand conditions made based on its superior comparative performance relative to other Cynodon accessions in glasshouse and field trials, the New Zealand registered variety ‘Grasslands AgRiDark’ was released in 1999. PBR Certificate Number 3716, Application Number 2004/299, granted 20 January 2009.
