Table 1 Manual scoring metrics for seven external fruit quality traits

From: A novel 3D imaging system for strawberry phenotyping

External quality parameter Scoring metric
Achene number Number of achenes visible, without disturbing calyx
Calyx size Maximum Euclidean distance between any pair of points on the calyx
Colour Scale 1–8 (strawberry colour chart for experimental ends, Ctifl, France)
Height Dimension of fruit from centre of calyx to tip of nose
Length Greatest dimension of fruit orthogonal to the height
Width Greatest dimension of the fruit orthogonal to both height and length
Volume Volume of displaced water when fruit was completely submerged
