Cotyledons were used as explants in the rapid shoot regeneration method in hemp.
TDZ applied in MS medium were found to be capable of inducing in vitro shoots from cotyledons superior than BA and ZT.
Younger cotyledons (2–3 DAP) produced significantly higher regeneration frequency than elder ones (5–6 DAP).
The regeneration method was suitable while partly genotype dependent.
The method may afford an alternative method for micropropagation and germplasm conservation, and the in vitro plantlets may be suitable to set up a transformation system.
