• Closely related to Mace, with similar adaptation and yield
  • AH quality classification with low screenings and high test weight
  • Suitable for wheat on wheat situations
  • Quick-mid maturity, similar to Mace
  • Tolerant to Clearfield® Intervix® herbicide

Breeders comments

Being very closely related to Mace, Hammer CL Plus (tested as OAGT0016) shares a similar maturity and sowing window, as well as wide adaptation and suitability to southern cropping regions. Hammer CL Plus has finer, and therefore weaker straw than Mace, so growers may observe some leaning or lodging when Hammer CL Plus is grown in higher yielding situations.

Along with having an AH quality classification in Victoria, Hammer CL Plus produces grain with low screenings losses and high test weights.

Hammer CL Plus also offers one of the best disease resistance packages in a Clearfield® variety, and with good levels of resistance to both CCN and yellow leaf spot, lends itself to wheat-on-wheat situations which is common practice in low-medium rainfall environments.
