CoAXium® Barley Varieties
AGT barley varieties that are part of the CoAXium® Barley Production System are bred in Australia, for Australian conditions. These varieties have been chosen for their high and stable yield, wide adaptation, grain quality and disease resistance, whilst carrying tolerance to Aggressor® AX herbicide to give growers another weapon in the fight against grass weeds.

The Strength of CoAXium® Barley Stems From Strong Varieties.
Following the release of Titan AX – the world’s first CoAXium® barley – and PegasusAX, AGT has now introduced a new addition to the CoAXium® family: AGT- Bunyip IA
Titan AX, derived from Compass, features a tall plant type with strong early vigour, making it well-suited to low–medium rainfall environments, though more prone to lodging. In contrast, PegasusAX, with a Hindmarsh-type background, offers a shorter, more compact plant structure and is better suited to medium–high rainfall zones.
Newly released in 2025, AGT-Bunyip IA is a world-first in its own right — the first barley variety to combine dual herbicide tolerance to both ImiTol™ (imidazolinone herbicides) & CoAXium® . It delivers higher yields with a compact plant type, improved standability, and broad adaptation across southern Australia.
