Abstract
The limited availability of disease-free, high-quality seed tubers is a major constraint for the production of white potato worldwide. This research aimed to develop a non-destructive method for fast multiplication of high-quality seed potato tubers using the apical stem cuttings that can be repeatedly harvested from the first generation of disease-free plants (G0) for further propagation. Using soilless cultivation systems in the screen house, a higher growth rate and yield was obtained from G0 cuttings grown in the aeroponics system compared with the hydroponics system. Both PE foam and rockwool were suitable to be used as stem holder for the aeroponically grown cuttings. Cultivation of the G0 cuttings in the field was successful, with each cutting produced an average of 5.4 to 6.3 tubers per plant under different spacings and rates of NPK fertiliser applied. The yield of field-grown G0 cuttings was influenced by plant spacing and application rate of NPK fertiliser. A plant spacing of 20 cm × 20 cm produced the highest seed tubers yield and the optimum application rate of NPK fertilizer was 600 kg/ha. Utilisation of the apical stem cuttings of G0 plants may reduce the quantity of seed tubers required per unit of planting area, which in turn would reduce the production cost while increasing the supply of seedling and the yield of individual G0 seed tubers.
