Abstract

Persistent and productive cultivars of limpograss (Hemarthriu altissima (Poir.) Stapf et C.E. Hubb.) are required if the species is to be useful in Northland cattle systems. A study was undertaken to investigate plant morphological traits, adaptation and persistence of 8 accessions. A series of abandoned research sites was revisited to determine long-term persistence and adaptation. Trials were established at 4 new sites throughout the northern North Island to assess morphological variation and plant survival. There was considerable variation in morphological traits assessed and plant survival, allowing scope for future selection. Bigalta used in earlier research trials had largely failed to persist under normal pasture management practices. Future work should use the cultivar Floralta. Keywords: adaptation, flowering, Hemarthria altissima, leaf, morphological variation, persistence, seed, stolon
