Scientists develop wheat types to resist heat, drought

By Neena Bhandari

Sydney, 21.03.2022 (SciDev.Net): Australian scientists have identified a novel combination of genetics that may help wheat survive in hot and dry conditions, thereby increasing yields and assisting farmers to adapt to climate change-induced heat and drought stress.

Wheat is the third-largest grain crop in the world, supplying about 20 per cent of the total calories and protein in the human diet worldwide, notes the research by CSIRO, Australia’s national science agency, published in Nature Climate Change on 7 March.

Researchers have identified three novel alternative dwarfing genes that enable wheat seeds to draw moisture stored twice as deep from the soil than current varieties. “We have genetics that can allow us to sow earlier and deeper up to 120 millimetres while keeping the plants short and allowing for very long coleoptile, which is the shoot that grows from the seed to the soil surface,” says Greg Rebetzke, co-author of the study and chief research scientist at CSIRO Agriculture and Food.

Aboriginal knowledge could unlock climate solutions

Cairns [Queensland], December 17, 2014 (IPS) – As a child growing up in Far North Queensland, William Clark Enoch would know the crabs were on the bite when certain trees blossomed, but today at 51 years he is noticing visible changes in his environment such as extreme climatic conditions, frequent storms, soil erosion, salinity in fresh water and ocean acidification.

“The land cannot support us anymore. The flowering cycles are less predictable. We have to now go much further into the sea to catch fish”, said Enoch, whose father was from North Stradbroke Island, home to the Noonuccal, Nughie and Goenpul Aboriginal people.
