Figure 3From: Association mapping in sunflower (Helianthus annuus L.) reveals independent control of apical vs. basal branching Principal component analyses (PCA) showing clusters of various branching types in the association mapping population. The first dimension accounted for 77.4%, 82.3%, and 83.1% of the observed variation in GA, IA, and BC, respectively. The second dimension accounted for 16.4%, 13.0%, and 12.0% of the variation observed in GA, IA, and BC, respectively. Each dot represents a line and the color of the dot represents the type of branching.Back to article page
