Abstract

Vegetative multiplication of potato is used routinely to produce disease-free seed tubers and to multiply new potato varieties for trials. The conventional methods of vegetative propagation using virus-tested stem cuttings allow production of 800–900 plants from a single plant in 3 years (Hussey & Stacey, 1981). Use of in vitro propagation allows much more rapid rates of multiplication of new varieties of potatoes (Wooster, 1984). Axillary buds taken from a few tubers can be multiplied to 500 plants within 4 months by repeated subculturing of nodal cuttings on artificial media in sterile conditions.
