Optimising cultivar and time of sowing in wheat locations

To investigate whether Winter varieties bred for NSW can be grown successfully in SA.

Key messages
  • The highest yielding treatment was Trojan sown on the 26th May at 5.96 t/ha.
  • RAC2341 has shown good adaption to SA conditions as a Winter variety and its potential release could provide growers with an earlier sowing option.
