ABSTRACT
Jerusalem artichokes can be propagated using tubers, rhizomes, slips, stem cuttings, tissue culture, and seeds. Tubers represent the primary choice for commercial production of the crop. While rhizomes are important in the regeneration of wild populations, rhizomes, slips, and stem cuttings represent secondary methods of asexual propagation that are occasionally used to expand the numbers of a particular clone when tubers are not available. Tissue culture is used for long-term storage of clones in germplasm repositories and for the production of transgenic plants. Unlike sunflower (
Helianthus annuus
L.), where seed represents the primary means of propagation, seed is not a viable method for the production of Jerusalem artichokes and is used only in breeding programs to obtain the progeny from crosses.
