Other claims from this paper (7)
- Intervention effect The high-TE wheat cultivar Drysdale yielded on average 187 kg/ha more than its low-TE parent Hartog in the rainfed region under present climate.
- Intervention effect Under elevated CO2 the yield response of Drysdale was greater, averaging 284 kg/ha.
- Observation The highest yields were not necessarily directly correlated with the highest TE.
- Intervention effect The benefit of the TE trait for Drysdale over Hartog ranged from 102% to 118%.
- Observation The potential annual cost-benefit of the higher-TE trait across Australian wheat areas totals AUD 631 MIL.
- Intervention effect Elevated CO2 raises the nation-wide benefit to AUD 796 MIL in a 2°C warmer climate.
- Intervention effect If rainfall is also reduced by 20%, the nation-wide benefit is slightly lower at AUD 715 MIL.
