Description In vitro micropropagation protocol for Basella rubra regeneration was tried through proliferation of axillary shoots of the
potted mature plant. The improved seed germination (70%) was recorded upon 2% urea treatment. The nodal shoot segments
from matured potted plant were used to initiate the multiple shoot proliferation. The shoot segments exhibited 70% shoot
initiation when cultured on Murashige and Skoog (MS) medium supplemented with Indole-3-acetic acid (IAA)+N6 – Benzylaminopurine (BAP) (0.25+2.0 mg/L) and BAP+Kinetin (Kin) (2.0+0.5 mg/L) respectively. Multiple shoots (5–6) were
obtained on MS medium supplemented with BAP+Kin and IAA+BAP respectively. When compared with silver nitrate
(AgNO3) (2–40 µM) and activated charcoal (AC) (0.1–1.0%), the MS medium devoid of any plant growth regulator showed
good number of shoots (5.48±2.42), elongation (15.64±2.42 cm) and root length (14.52±2.78 cm). Upon transferring
of regenerated microshoots to MS medium, simultaneous elongation of shoots with more shoot number, shoot length and
rooting was achieved during four subcultures that carried out at 6 weeks’ interval. The regenerated in vitro shoots showed
100% rooting in MS medium and also in MS medium supplemented with 0.1–1.0% AC. Hundred percent survival of micropropagated shoots well rooted was established successfully under greenhouse condition and the plants were subsequently
acclimatized and transferred to the feld conditions wherein 90% success rate was noted.
