Summary Four different numerical methods using only intensity of phenolic spots, intensity of the spots and the spot‐areas and the spot‐areas alone, were assessed for their value in defining relationships among Citrus species where such relationships are thought to be well known. It was found that biochemical distance or biochemical difference calculated from the spot area without squaring and by simply adding the differences most useful. This method reduced the over‐weighting of characteristic spots that occurs when the differences are squared.
