Pyramiding greater early vigour and integrated transpiration efficiency in bread wheat; trade-offs and benefits

Increases in wheat performance under drought have been demonstrated in selection for factors contributing to greater water-use efficiency. Crop growth models have indicated the potential for significant increases in wheat yields across a wide range of wheat growing environments when both greater early vigour and higher integrated transpiration efficiency (TE) are selected together. However, greater early vigour comes with the possible trade-off...
