Manual scoring metrics for seven external fruit quality traits

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
