Researchers from The University of Queensland hope wild millet from outback Australia’s Channel Country could help feed the world as climate change impacts established grain crops.

PhD candidate and Global Change Scholar Rahul Chandora at the Queensland Alliance of Agriculture and Food Innovation is working with the Centre of Excellence for Plant Success and Mithaka Corporation to analyse the genome of Echinochloa turneriana or channel millet.
Mr Chandora said channel millet grew in the border region between Queensland, the Northern Territory, South Australia and NSW.
“Millet has great potential to diversify our traditional diet as it’s highly nutritious, highly adaptive, climate-resilient and gluten-free,” he said.
“Millets are cultivated on all continents, particularly in India and Africa, but use of the crop is still confined to Indigenous communities — we want to see it become mainstream.”
For the first time in Australia, a plant genetics study is being undertaken in collaboration with an archaeological project.

Mr Chandora said channel millet might once have been an important food for the Mithaka people of central Australia, something that may be confirmed by his research and a project called Testing the Dark Emu hypothesis.
“Analysing the genome of wild channel millet will help evaluate its past use and determine its future potential,” Mr Chandora said.
“Domesticated millet species have lower yields than other cereals and production is affected by issues like lodging, seed shattering and seed size.
“If we can find out more about channel millet’s genetics, we can identify favourable traits and use gene editing technology to rapidly domesticate it.
“We hope then to expand the gene pool of farmed millet and eventually shift our reliance from cereals like rice, wheat and maize.”
The research team will also look at the conservation and management of channel millet.
“Because this is a wild species, we need to conserve it in its natural habitat and to collect and store it in seed banks as well,” Mr Chandora said.
“Climate change will mean genetic resources like this could erode very quickly and without a concerted effort, we won’t have access to them in the future.
“We need to find new crops to meet the nutritional needs of the world’s rapidly growing population and that makes this very important and interesting work.”
The United Nations has recognised the potential of the crop and declared 2023 the International Year of Millets.
It is no secret there is a need to find new crops to meet the nutritional needs of the world’s growing population. Millet could be one of them.
