Australian canola growers in dry
areas will receive a boost this year with the release of early
maturing canola variety, CB Tanami.
CB Tanami proved a winner last year, yielding well in low
rainfall regions in Grains
Research and Development Corporation (GRDC) supported
National Variety Trials (NVT).
CB Tanami and CB Boomer are recent additions to low rainfall
growers’ “armoury” for battling drought.
CB Tanami matures well under drought stress, has moderate oil
and protein content and moderate resistance to blackleg, while
CB Boomer has very large seeds and vigorous early growth,
combined with a determinate growth habit and rapid maturity.
Buntine grower and GRDC Western Panel member, Merrie
Carlshausen, welcomed the new varieties, especially after last
year’s poor rainfall.
These early maturing TT canola varieties are adapted to the low
rainfall cropping zones of southern Australia, which includes
Mrs Carlshausen’s farm.
CB Tanami has been bred to yield high in the wheatbelt of
southern Australia and its excellent early vigour and drought
tolerance enables it to “pull through” the tough seasons, such
as the one experienced in 2006.
In NVT trials in Western Australia, South Australi and New South
Wales at low to medium rainfall sites in 2006, CB Tanami
outyielded ATR-Beacon, Tornado TT, Bravo TT and ATR-Stubby.
CB Tanami’s oil content was equal to ATR-Stubby and about one
per cent lower than Bravo TT and Tornado TT.
Canola Breeders Western Australia Pty Ltd (CBWA) released CB
Tanami in November 2006 and CB Boomer the previous year.
The two latest varieties, CB Boomer and CB Tanami, were
standouts in the wheatbelt in 2006, according to the CEO of
Canola Breeders Western
Australia Pty Ltd (CBWA) and
University of Western Australia Associate Professor Wallace
Cowling.

What are CBWA Demonstration
growers saying about CB™ Tanami* and CB™ Boomer* ?
One of CBWA’s marketing strategies
has been to test drive their new varieties using 5ha sites on
grower properties one year before release. CBWA seeks growers
who are prepared to test our new varieties alongside varieties
they are currently growing and to provide us with feedback on
their performance. In this way we learn what growers think of
our new varieties, you have an opportunity to view these mini
paddocks grown locally and we gain valuable feedback on how to
serve you better in the future.
Mindarabin farmers, Ron and Gavin Beeck, grew a demonstration
plot of CB™ Tanami* next to their Tornado canola crop in 2006.
"We noticed that Tanami
established better with the tough start and from there it never
looked back. The good establishment and ability to hold on in
the dry meant that we harvested 1.2 t/ha of Tanami compared with
0.8 t/ha of the surround crop Tornado. The oil of Tanami did
suffer with the dry finish, but the yield more than made up for
this – we've ordered Tanami for next year!"

Rohan Day grew 5 ha demo's of CB™ BoomerA and CB™ TanamiA on
his Burracoppin farm in 2006.
"There isn't much canola grown out here east of Merredin,
especially in dry years, so we were keen to try some new
varieties. We were very impressed with Boomer all year – maybe
the large seeds allowed it to get a better start and find the
moisture from the summer rains. Either way, the Boomer and
Tanami certainly had it over the Stubby surround crop. Boomer
and Tanami both yielded about 0.6 t/ha while the Stubby only
managed 0.25 t/ha."

Mike Kalajzic grew a 5 ha demo of CB™ TanamiA on his Cadoux
farm in 2006.
"We normally expect about 340 mm of rain, but we only received
200 mm in the growing season. Tanami's short season nature
seemed to really shine out - it was a winner by a long shot. It
yielded 37% higher than Stubby and also recorded a better oil
result than Stubby at 41.2% compared to 39.8%. I was very
impressed with Tanami - it's definitely a variety aimed for my
area."

Coorow grower and COGGO member, Rod Birch, grew CB™ Boomer in
5-ha CBWA demonstration plots on his farm in 2006.
According to Rod, “Catalina Farms received just 125 mm rainfall
in the growing season (April - October) - it has been a tough
year. We sowed CB™ Boomer at 3 kg/ha and harvested 0.90 t/ha
with 43.3% oil and 25.1% protein. In contrast, ATR-Stubby at the
same seeding rate in a neighbouring strip yielded 0.84 t/ha with
40.2% oil and 24.5% protein. We are delighted with this
performance of CB™ Boomer in such a tough year.”
