Wheat varieties Wyalkatchem,
Young and potential release WAWHT2750 proved to be the highest
yielding varieties in the Great Southern and Lakes region in the
2006 Department of
Agriculture and Food crop research trials.
Also performing well was the Department’s newest noodle wheat
variety, Binnu, which yielded similar to Calingiri at Katanning
and higher than Arrino at Newdegate.
Research officer Brenda Shackley, who will be speaking at the
Department’s Jerramungup Regional Crop Update on 21 February,
said the trials were sown between late May and mid July in
Katanning, Newdegate and Jerramungup with the aim to test the
performance on the wheat varieties across a range of sowing
times.
A full review of the wheat research trial work will be provided
during other Regional Crop Updates in Merredin, Jerramungup,
Northam, Corrigin, Buntine, Esperance and Dongara over the next
two weeks.
“The results of the trials saw average yields from 1.6 tonnes
per hectare at Katanning and Newdegate and 0.6 tonnes per
hectare at Jerramungup,” she said.
“The low yield results were as a result of the dry season. The
season was relatively short with a late start to seeding and
very dry spring in all areas.
“The higher yielding varieties tended to be those with a shorter
maturity time.”
Ms Shackley said as sowing times were delayed, grain protein
increased, as did screenings in most cases.
“The preliminary data shows that Wyalkatchem was not prone to
high screening and EGA Eagle Rock, EGA Jitarning and Yitpi also
performed well.
“Grain protein levels below 11.5 per cent were achieved for the
noodle wheats, including Binnu, where they were sown in mid-June
in the Katanning and Newdegate regions.
“The four soft wheat varieties grown in the Katanning trial,
Bullaring, Datatine, EGA 2248 and EGA Jitarning, were all above
the maximum of 9.5 per cent for all sowing times.
“This coupled with high screenings, severely reduced the gross
income of the soft wheats.
“In a short season such as 2006, it is recommended not to grow
soft wheat due to the high risk of not meeting the soft wheat
standards.”
