ABSTRACT

Coleus forskohlii Briq. is the only known natural source of forskolin. Micropropagation provides
an opportunity to maintain type-to-type plant species and can produce a large number of plants
from single clone. the maximum shoot proliferation (99.00 per cent) was noticed in BAP (2.00 mg l-
1). The best growth regulator treatment for rooting of coleus microshoots was IBA (0.2 mg l-1) in half
strength MS medium The growth regulator combination which produced highest percentage of
callus induction from leaf bit was 2, 4, D (2.0 mg l-1). For better rooting of callus derived microshoots,
the ideal medium was found to be half strength MS medium supplemented with IBA (0.2 mg l-1).
Direct and indirect organogenesis of coleus were compiled and presented here under
