Fig. 2

Frequency distribution and correlation scatterplots for pre-harvest sprouting (PHS) score of doubled haploid (DH) lines. Frequency distribution histograms with normal distribution curve (blue line) for PHS of DH lines grown at Edmonton 2019 (EDM19), Ithaca 2018 (ITH18), Lethbridge 2018 (LET18) and Lethbridge 2019 (LET19) as well as pooled data are shown on main diagonal. The means of the parental genotypes AAC Tenacious and AAC Innova are indicated by blue and red dots, respectively, beneath frequency distribution plots. Scatterplots with regression lines, linear (blue) and exponential (red), for each environment pair are shown on the left side of the main diagonal. Orange dots on scatterplots represent PHS score of DH lines. Correlation coefficients (r) between each pair of environments, and each environment and the pooled data are displayed on the right side of the main diagonal. Color intensity (light red to dark red) on r boxes indicate the depth of association between environments under evaluation
