An Objective Method of Recording and Comparing the Shapes of Carrot Roots

Abstract
It is assumed that the shape of a carrot root lies between that of a cylinder and a cone having the same maximum diameter and length as the root. By determining the diameter, length and weight of roots it is shown that a statistical comparison of the shapes of populations of roots is possible. This is illustrated by an analysis of data on ten varieties of carrots. A method of constructing the mean shape of a population of roots is also described.
