AgriFutures Australia funded a research project with the objective of transitioning quinoa (Chenopodium quinoa Willd) from a niche/cottage/organic crop to wider adoption across Australian broadacre farming environments and to develop variety options. We undertook field evaluation of quinoa advanced lines in combination with different sowing dates and seed rates at Kununurra in the north, Manjimup in the south-west and at six locations in the Wheatbelt of Western Australia. Results demonstrated that quinoa could yield well in both irrigated and rainfed conditions. The line BEW performed better at Kununurra under irrigated conditions when sown in mid April with a seed rate of 1-3 kg/ha (up to 2.0 t/ha) and at Geraldton under rainfed conditions sown in early June with a seed rate of 2.5 -5 kg/ha (3.0 t/ha). BEW is expected to be released as a new variety at the national level by 2021. Medusa seems to perform better than BEW in southern WA. The varieties tested showed sensitivity to frost and high temperature (daily maximum above 35oC) at flowering to seed development stages, and to head sprouting at maturity.
