Multiplication rate of selected potato cultivars in vitro through single node culture
A study was carried out in the tissue culture laboratory at the National Potato Research Centre (NPRC), Tigoni, Kenya to determine the multiplication rate of selected potato cultivars when micropropagated through single node culture. Seven potato cultivars were subcultured on solid media for three consecutive cycles (each cycle took three weeks). This was repeated twice. Data collected was the number of single-node cuttings that were generated from each node after subculturing. Generally, there were significant differences (P≤0.05) on the number of single node cuttings generated among the potato cultivars, among the subculture cycles and in the interaction between genotypes and subculture cycle.
