Company says the product is a new slow and steady wheat for early sowing
(October 31, 2024) - InterGrain announced the release of Mammoth, a new very slow spring maturity APW wheat variety.
Wheat Breeder Dr. David Tabah says Mammoth’s unique phenology and high yield potential is set to offer an excellent variety option for very early sowing and early break scenarios in medium-high rainfall regions.
“Trialled as IGW6755, Mammoth has stood out in our breeding program as it has shown very stable yield performance and flexibility in maturity across different seasons and environments compared to quick-mid winter wheats,” Tabah says.
“Mammoth is a versatile wheat variety to have in the silo and use when there is an opportunity to sow early in an early break scenario. Its ideal sowing window is from late March to mid April, with its maturity sitting slightly quicker than Illabo.
“Winter wheats have a vernalization requirement, requiring cold temperatures to trigger flowering. Mammoth does not have a vernalization requirement, allowing it to continue to develop using day length as the main trigger for flowering.
“This attribute allows Mammoth to respond to seasonal conditions and minimize frost risk.
“We have seen Mammoth exhibit flexibility in its phenology and further testing is underway to gain a deeper understanding about how Mammoth responds to environmental conditions.”
Over the past two seasons InterGrain has entered Mammoth into a number of external partner trials, including the Department of Primary Industries and Regional Development’s (DPIRD) wheat agronomy sowing time response trial. In 2022 and 2023, Mammoth demonstrated a very stable yield performance when sown in its ideal sowing window compared to quick winter wheat Illabo, showing its potential for Autumn rainfall sowing opportunities.

Mammoth has a good all-round disease resistance profile including good yellow spot (MRMSp) and stripe rust (MRMSp – WA pathotype) resistance.
Mammoth is classified as APW in the Western and Southern zones. It has adequate grain quality attributes, however can have a smaller grain size and if sown outside its optimum sowing window and may produce higher levels of screenings.
Mammoth is available for the 2025 season from InterGrain Seedclub Members and resellers. For those who would like any more information about this unique maturing wheat, contact your local InterGrain Territory Manager.
