Summary
Plants regenerated directly from potato stem explants and from callus derived from single potato stem callus cells were compared with plants from rooted lateral buds as controls. There was phenotypic variation in explant and cell cultures: grossly abnormal, albino and green, shoot-like and root-like structures either failed to root or establish and survive in soil but most surviving plants showed a range of character variability similar to the controls.
Explant and cell culture-derived variation is discussed in relation to the improvement of specific characters in commercial potato cultivars.
