To investigate the influence that sowing date had on the phenology, grain yield and quality of 12 wheat genotypes.
• New winter genotypes had different phenology responses compared with current commercial genotypes.
• Frost significantly affected phenology and grain yield responses in 2017.
• The highest grain yields were achieved through various sowing date × variety combinations.
• Best management practice is matching varietal phenology with sowing date, however, pre-flowering phases had a significant influence on grain yield responses.
Twelve wheat genotypes with varying responses to vernalisation and photoperiod were sown on three sowing dates: 28 March, 12 April and 1 May 2017.
