Breeders comments

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.
