Early sown NVT MET data from the northern region has established that Coolah is the highest yielding slower maturing spring variety suited for planting in late-April and early-May. It is well adapted to the northern region and backs up this adaptation with a solid disease package of resistance to each of the rusts and intermediate resistance to yellow leaf spot.
Coolah is also slightly shorter in stature than EGA Gregory, resulting in a lower susceptibility to lodging.
Coolah’s maturity is driven by moderate photoperiod and vernalisation requirements, and matches EGA Gregory in most environments. Sown at the end of April into early May, Coolah will maximise early moisture availability whilst still avoiding frost risk in late August.
Commercial quantities of Coolah may be available through AGT Affiliates, or your local retailer.
Coolah is able to be traded between growers upon the completion of a License Agreement as part of AGT’s Seed Sharing™ initiative.
Coolah is protected by Plant Breeders Rights (PBR) and all production (except seed saved for planting) is liable to an End Point Royalty (EPR), which funds future plant breeding.
Coolah growers will be subject to a Growers License Agreement that acknowledges that an EPR of $3.5/tonne + GST has to be paid on all production other than seed saved for planting.
