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.

Short Days

Single-node cuttings of 3 cultivars were planted in such a way that the buds were some centimetres above the soil surface. Some of the plants were grown under long-day conditions, the others under short days during stem growth, this being favourable to tuber formation in normal plants. Stems growing from the buds showed abundant tuber formation in the leaf axils of Jaerla (early) and Bintje (mid early), especially under short-day conditions, but fewer tubers were formed in Alpha (late). This cultivar formed many thickened branches instead of tubers under short-day conditions. Under long days Jaerla and Bintje formed many above-ground tubers, whereas half of the cuttings of Alpha did not form tubers. When planted, above-ground tubers produced good yields.
