To increase our understanding of what drives flowering time in durum, yield and yield stability can be improved.
• There is limited variation in flowering times of Australian durum varieties.
• The main driver of flowering time in durum is photoperiod – this means there are currently no durum varieties suited to pre-ANZAC day sowing, as they flower too early.
• Even the best performing durum varieties were unable to out yield Scepter in any environment, despite similar flowering times.
• Durum wheats have a greater susceptibility to frost and crown rot than bread wheats.
