From: Climate change effect on wheat phenology depends on cultivar change
Mean heading day observed for western Germany and simulated with the phenology model (parametrized separately by field experiments conducted in 2015/2016 and 2016/2017) considering the climate effect (fixed sowing date and cultivars), combined climate and sowing effects (year- and grid-specific sowing date and fixed cultivar), and combined climate, sowing and cultivar effects (year and grid-specific date and changing cultivars) for the period from 1952 to 2013 for western Germany.
