Researchers in Australia have developed a form of salt-tolerant wheat that could help address the global food crisis by allowing farmers to grow crops in soil with high salinity. They created the new form of wheat by crossing a modern strain with an ancient species, a pairing that resulted in a hearty new kind of plant that can withstand soil that most commercial forms of wheat can’t survive in.
The wheat was developed using non-genetically modified crop breeding techniques — think good old fashion genetics, no DNA splitting involved — and was revealed in an article in the journal Nature Biotechnology. The research was completed by a team at the University of Adelaide in Australia and the group says they are the first in the world to prove the development of a salt-tolerant agricultural crop. “This work is significant as salinity already affects over 20 percent of the world’s agricultural soils, and salinity poses an increasing threat to food production due to climate change,” said Dr Rana Munns, one of the researchers in the project.
Most plants have no salt tolerance and thus rising sea levels could spell disaster for global crops. As the global ice caps melt and sea levels rise, salty sea water mixes with fresh water sources on land and seeps into soil causing plants normally grown there to perish. The researchers are now working to use their breeding process to develop a salt-tolerant strain of bread wheat.
