Research suggests that winter wheat varieties with long coleoptiles (pointed protective cover that encases the emerging shoot) have the potential to raise average yields across southern Australia. For NSW this aligns with areas south of Coonabarabran. Two main reasons support these findings. Firstly, wheat plants with long coleoptiles can be sown much deeper, for example 12.5 cm compared to the current practice of around 5.0 cm depth.
