Methods were developed in the present investigation for cloning and large scale plant production of Passiflora foetida L. germplasm selected from the East-Coast region of South India. Nodal shoot segments were used as explants. The explants were dressed and surface sterilized with 0.1% (w/v) HgCl 2 . Multiple shoots were induced (6.13 ± 0.22 shoots per explant) by proliferation of nodal shoot meristems on Murashige and Skoog (MS) semi-solid medium + 2.0 mg l À1 6-benzylaminopurine (BAP). The shoots of P. foetida were further multiplied (16.45 ± 0.44 shoots per explant) on MS medium + 0.5 mg l À1 each of BAP and Kinetin (Kin). The in vitro generated shoots were rooted on half-strength MS medium containing 2.5 mg l À1 indole-3 butyric acid (IBA). By this method 67% shoots were rooted. About 97% shoots were rooted ex vitro (8.33 ± 0.29 roots per shoot) when the cut ends of the shoots were treated with 300 mg l À1 IBA for 5 min. The in vitro rooted plants were hardened and acclimatized in the greenhouse and successfully (100%) transplanted to the field. Ó 2015 Production and hosting by Elsevier B.V. on behalf
