Genetic correlations of flowering times in the same B. stricta recombinant inbred lines exposed to six laboratory and two field environments. If laboratory conditions reasonably simulated natural environments, we would expect a tight correlation between flowering phenology in lab and field. Instead, our data indicate that family-mean flowering times are significantly correlated in laboratory and Montana field conditions (a), but little of the genotypic variation in flowering time in the field is explained by conditions in the growth chamber, reflected in the low R² value. We found no significant correlation between family-mean flowering times in our Colorado garden and any of our six growth chamber conditions (one representative growth chamber treatment is displayed in (b)). Furthermore, flowering time values are uncorrelated between our disparate field sites (c), highlighting the importance of investigating life-history transitions and ecologically relevant traits under multiple natural environments. The genetic correlation of flowering time is much tighter in comparisons of different growth chamber treatments (d). The data presented in these panels come from Anderson et al. (2011, 2012a), and are available in the associated Dryad files.
