Table I. Summary of the subset of traits automatically measured from the plant mesh used for the reported QTL analyses.

Additional descriptions of the methods used to obtain the measurements are found in Supplemental File S1.

Trait Type	Measurement	Description of Measured Trait
Composite	Shoot height	Vertical distance from the lowest shoot point to the highest shoot point, including leaves and inflorescence
	Shoot surface area	Surface area of the entire shoot
	Shoot center of mass	Vertical distance from the lowest shoot point to the shoot’s center of mass
	Shoot compactness	Surface area of the smallest convex polyhedron that contains the entire shoot (i.e. convex hull surface area)
Organ level	Shoot cylinder height	Vertical distance from the lowest shoot cylinder point to the highest shoot cylinder point
	Leaf length	Length of a leaf
	Leaf surface area	Surface area of a leaf
	Leaf width	Width of a leaf
	Leaf angle	Angle at which a leaf emerges from the shoot cylinder
