Summary
The behaviour, over 3-8 generations of vegetative propagation, of nine potato clones showing variable expression of the spectacle pattern is described. Clones differed in expectation of spectacle frequency at equilibrium from 4 to 88 per cent. Variation in spectacle expression depended more upon undefined internal factors than upon environment.
