Fig. 2: Yield trends in top and check cultivars over time in wheat multi-environment trials.

Symbols represent the best linear unbiased estimators (BLUEs; see Methods) calculated for fungicide-treated top cultivars (empty upward triangles) and treated and untreated check cultivars (blue circles and red downward triangles). The name of the reference check cultivar is indicated within each panel. Baguette 10 (a), Baguette P11 (b), and Klein Proteo (c), Buck SY 200 (d) in Argentina (AR); Claire (e), Cordiale (f), and Grafton (g) in United Kingdom (UK); Apache (h) in France (FR), and Endurance (i) and Duster (j) in the United States (US). Slopes (kg ha−1 y−1) and significance of regression analyses are indicated within each panel (P < 0.1x; P < 0.05*; P < 0.01**; P < 0.001***). Vertical lines in check cultivars indicate the ± one standard error from the BLUEs. Source data are provided as a Source Data file.
