WYALKATCHEM, Bonnie Rock, Carnamah and the new Grain Biotech Australia variety, Ruby, will be among the top yielding wheat varieties in this year's Crop Variety Testing (CVT) trials across the state, according to AgriTech managing director, Peter Burgess.
AgriTech is contracted to carry out the GRDC-funded Crop Variety Testing trials at 12 locations from Mingenew to Esperance.
The 39 wheat varieties under scrutiny at Mingenew this year were sown at 75kg/ha on May 13.
"Right across the state, it looks to be a fantastic season," Mr Burgess said.
"Yields across our 12 Crop Variety Testing trial sites between Esperance and Mingenew look to have four tonne potential this year."
Mr Burgess said all new wheat released needed at least medium to high triple rust resistance.
"Mediocre, stop-gap varieties are not the solution," he said.
"We have a very rust susceptible noodle variety in Arrino and desperately need a new variety with similar attributes but a stronger disease package.
"Bonnie Rock is an excellent all round variety, with stem and leaf rust resistance but it is prone to stripe rust."
Trials last year showed EGA Blanco, a hard grained variety suitable for the steamed bread market had intermediate rust resistance.
Stilletto, with an Australian Premium White rating, had performed well across a range of soil types and environments over the last few years, but it had poor leaf and stripe rust resistance.
