Phenotypic characterization of the RIL parents. Images of the (a) BR007 and (b) SC283 root systems. Phenotypic means for (c) root diameter (RD), d total root surface area (SA), surface area of roots in the diameter classes of (e) 0–1 mm, (SA1, designated as very fine roots), f 1–2 mm (SA2, fine roots) and (g) 2–4.5 mm (SA3, thicker roots). All surface area measures are in cm2. Root images and root morphology traits were assessed after 13 days in nutrient solution with low-P. h Grain yield (Gy) was assessed in a low-P soil with one hundred twenty reps. The proportion of roots within each diameter class relative to total surface area of the root systems are shown as percentages in e, f and g. Error bars are shown. Different letters indicated statistical differences by the t-test (p-values ≤ 0.10)
