Complementary Phenotyping of Maize Root System Architecture by Root Pulling Force and X-Ray Imaging

Figure 3

RPF and 3D root system architecture traits are strongly associated with each other and root mass (grams). Heatmap of RPF and its 20 most correlated traits (10 most positive and 10 most negative) in the G2F 2017 (a) and SAM 2018 (b) datasets. Regression of example traits positively correlated to RPF such as fractal dimension side/top (c, d) and surface area (e), and example traits negatively correlated to RPF such as convex hull volume (f), within the G2F 2017 dataset. Regression of example traits positively correlated to root mass (grams) such as RPF (g), volume (h), and number of tips (i), and example traits negatively correlated to root mass (grams) such as solidity vertical histogram-01 (j), within the SAM 2018 dataset. Adjusted -squared values for c–j shown in respective plot insets.
