Longer season wheat to achieve higher yield in the high rainfall area locations
Aims

Exploring the potential of longer-season wheat to achieve higher yield in the high rainfall zone.

Key messages

Longer-season wheat with later flowering time produced higher yield than early flowering wheat. However, the high correlation between the time to anthesis and the time to terminal spikelet initiation makes it difficult to evaluate the relationship between yield and CPD independently. Increasing biomass from longer-season wheat is probably more promising trait than lengthening CPD to achieve higher yield in the high rainfall area.
