Summary
Fifty-five radish selections, comprising 39 named cultivars, were grown for classification based on morphological characteristics. The major characters used were the ratio of length to width of the hypocotyl, and the colour of the hypocotyl. Cultivars were further subdivided by the length of the longest leaf and the number of fully expanded leaves at harvest. The coefficient of variation is given for each cultivar. The classification identifies a total of 25 classes based on combinations of root shape and colour. These classes can then each be subdivided 25 times based on combinations of leaf length and leaf number.
