Aims

To examine the suitability of elite commercial and unreleased spring cultivars for hyper yielding regions.

Key messages

Clearfield trial
 45Y93 CL and 45Y95 CL were the standouts for grain yield, yielding above 5.6t/ha.
 The European spring cultivar AGFCA014520 was very tall but lower yielding compared to the best Australian bred cultivars.
 Oil was highest in the unreleased PS-21CL211 and PS-21XC318.

Glyphosate tolerant trial (Roundup Ready and Truflex)
 NCH20Q729 was the highest yielding and tallest cultivar.
 There was no difference in oil concentration in the glyphosate tolerant trial.

Triazine tolerant trial
 There was no statistical difference in yield between the four TT cultivars.
 ATR Wahoo and HyTTec Trifecta had the highest oil concentration.

Overall conclusions
 There were larger yield differences observed within trials than between trials. It is best to pick the appropriate herbicide tolerance required for a paddock than select the best cultivar within that herbicide tolerance group.
 Protein was higher than the winter screen, with an average of 21.8% meaning 34.3kg/ha nitrogen was harvested per tonne of grain harvested.
