SEED company AGT has released Catapult to the Australian market as a high-yielding wheat which provides reduced risk of underperforming when dry sown.
AGT wheat breeder James Edwards said variety choice was very important when it came to dry sowing, and Catapult was a new contender worth considering.
“Growers are continually looking for earlier sowing options that don’t compromise on yield,” Dr Edwards said.
“A variety like Catapult is a great choice for dry sowing because it maintains its high yield over a wide range of germination dates, including well into May, where it remains competitive with the benchmark variety, Scepter.”
In recent years, a substantial portion of Australia’s wheat crop has been planted dry, and in many instances germination of these crops has been delayed due to a later-than-anticipated season break.
“Catapult may be viewed as a longer-season Scepter, allowing growers to achieve Scepter-like yields when sown in late April.
“When sown towards the end of April, Catapult has taken longer for heads to emerge relative to Trojan and Scepter, but that accelerates when it is sown in May.
“We believe growers are likely to be able to plant Catapult a week earlier than they would plant Scepter, with this planting window extending well into late May, offering great flexibility to growers.”
When sown around ANZAC day, Catapult has consistently out-yielded Trojan, Cutlass and Yitpi, as well as other varieties used in this sowing window.
“The very high yield potential of Catapult relative to other varieties has been recorded across a large range of growing conditions and environments, highlighting its very wide suitability for most cropping programs.”
Dr Edwards said Catapult came out of a standard Mace cross, and he believed its unique combination of features that we believe would help growers increase productivity, while providing flexibility that has not been available previously.
He said Catapult was also one of the best choices for use in wheat on wheat rotations due to its disease-risk profile.
“Apart from Catapult, there are no other wheat varieties that combine this maturity type with cereal cyst nematode resistance, yellow leaf spot resistance and AH quality.”
AGT national marketing manager Dan Vater said Catapult’s wide adaptation would mean it could fit the front end of most growers’ cropping programs and be utilised as a second wheat in a rotation, a practice very common in low-rainfall environments.
“Catapult is very closely related to Scepter and shares its physical grain quality characteristics of high testweight, low screenings and AH quality classification,” he said.
