Two new rust resistant wheat varieties will be released at COGGO's bulk-up site at Northam next week.
RAC1372 and RAC1400, have been developed by Australian Grain Technologies (AGT), and will be unveiled next Tuesday.
RAC1372 is a Wyalkatchem derivative, but not as susceptible to yield reduction when challenged by stripe rust.
Trials have shown average yields 7pc higher than Wyalkatchem.
A mid-season variety flowering at a similar time to Wyalkatchem, it has a preliminary APW/AH classification for WA from the AWB.
RAC1400 is related to Camm, Stilletto and Spear, has excellent rust resistance and is particularly suited to medium to high rainfall areas with a longer growing season.
With similar adaptation to Spear, it will be welcomed by growers looking to reduce frost exposure.
COGGO chief executive, Geoff Smith, is enthusiastic about their release.
"The launch of a new variety is always an exciting event and this one offers growers the opportunity to see a range of AGT varieties side by side in the field, including the new RAC1372 and RAC1400, Gladius and Espada," he said.
* The launch starts at 10.30am with an address by AGT CEO Dr Stephen Jefferies and includes lunch and refreshments. Interested growers should contact Erin Baker, COGGO market development officer, Tel 9363 3400 for further details.
