SYMPOSIUM ON GRASSLANDS DIVISION'S NEW RYEGRASS 1. ARIKI, A NEW SELECTED PERENNIAL-TYPE RYEGRASS VARIETY

Abstract

Ariki (previously referred to as long-rotation ryegrass or new hybrid ryegrass) is a new variety bred from crosses between shortrotation ryegrass and N.Z. Perennial ryegrass. The success of Corkilll in breeding short-rotation from croSses between Italian ryegrass and perennial ryegrass led to this new improvement programme aimed at breeding a ryegrass with far more persistency than short-rotation but retaining its excellent seasonal growth and palatability. Corkill" was in charge of this programme from 1951 to 1957; sinde then it has been under the control of the author.
