It is great neurotonic,&#13;
immuno-modulator, adaptogen, tranquilizing, memory and learning enhancing, cerebral activator, antiulcer,&#13;
anti-asthmatic ayurvedic herb. Thus the micro-propagation of this plant is very necessary to&#13;
maintain the commercial demand and to preserve the germplasm of this endangered plant. The objective&#13;
of this study is to determine the easy and cost effective micro-propagation protocol. Direct shoot&#13;
regeneration was obtained on MS basal medium supplemented with different PGRs. Highest no. of&#13;
micro-shoots (128) produced on BAP (0.1 mg/l) using leaf explant which had been previously inoculated&#13;
on BAP (2.0 mg/l) i.e. shoot initiation medium. However nodal segment gave 88.2 shoots on BAP (0.5&#13;
mg/l), longer shoots (13.0cm) obtained on BAP (1.0 mg/l) + Kn (0.5 mg/l) using leaf explants. Best&#13;
response in in vitro rooting (13.1) achieved on MS __ampersandsignfrac12; + IBA (1.5 mg/l) and longest roots (6.4) occurred on&#13;
MS __ampersandsignfrac12; + NAA (1.0 mg/l). Rooted plantlets after acclimatization were transferred to green-house&#13;
conditions they show 100% survival rates. A key step in the analysis of plant DNA restriction fragments&#13;
is the purification of sufficient quantity of good quality DNA from fresh and healthy plant tissues, this&#13;
technique is ideal for isolation of DNA from Bacopa plants and the isolated DNA was used for RAPD&#13;
analysis. We used six primers in this analysis, all the profiles of DNA for all the smaples, were gave&#13;
similar results. This indicates that the abscence of intraspecific polymorphism among the samples.&#13;
