TWO VARIETIES of malting barley, Buff and Maximus, have successfully completed the first stage of of Barley Australia’s varietal-evaluation process, with Maximus to proceed to stage two trials this year.
However, Buff will not proceed into the second stage of trials until next year because insufficient grain is available for commercial evaluation this year.
The Board of Barley Australia considers recommendations from the Malting and Brewing Industry Barley Technical Committee (MBIBTC) for the various varieties currently under evaluation.
Barley Australia’s executive chair Megan Sheehy said while drought has impacted trial sites in eastern states, it is just one of the factors which can limit the amount of grain from a variety under evaluation.
“Certainly the drought would have had more of an influence on the eastern breeders because some trial sites would have been lost, but it’s a common problem for us every year to have insufficent grain for a range of reasons,” Ms Sheehy said.
“That can be caused by frost, head loss, or high proteins, and it’s why the selection rate for Malt 1 is around 25-40 per cent.
“We’re always dealing with environmental factors.”
