Fig. 7: Simulated difference in cultivar physiology across Europe.
From: Breeding changes water use of winter wheat across Europe

Differences in simulated seasonal maximum LAI (a), root hydraulic conductance (b) and above ground biomass at harvest (c) between a modern and a historic wheat cultivar relative to the historic cultivar over the major wheat grown areas in the European Union for the period of 1990–2020. Positive differences indicate that the respective variable has a greater value for the historic cultivar than for the modern cultivar.
