1 Geographic and environmental variation across 10 common garden sites.
Geographic and environmental variation across 10 common garden sites. (A). The 10 common gardens cover 1,866 km, 16.7° of latitude and 16.2 °C of mean annual temperature variation. The latitudinal transect of this study spans much of the natural distribution of switchgrass. The green/yellow layer is colored by historical annual temperature and is bounded by the US distribution of native switchgrass populations, calculated from georeferenced herbarium records. (B–D) The genotypic means of each of the two southern lowland (AP13, WBC) and two northern upland (VS16, DAC) grandparents as points. The phenotypic distributions of the F2 mapping population for three key traits are depicted as violin plots. Data from 2016 (left violin) and 2017 (right violin) are included for each site. David B.
