Effect of growth regulators on in vitro responses of strawberry for callus induction and shoot regeneration has been investigated. MS (Murashige and Skoog) medium supplemented with 2,4-diclorophenoxyacetic acid (3.0mg/l) and 6-Benzyl adenine (0.5mg/l) were found most effective in terms of percentage to callus inductions and degree of callus development. Calli derived strawberry explants were cultured in shoot formatting media supplemented with different concentrations of plant growth regulators. The combination of BA (1.5 mg/l) and a-Napthalene acetic acid (0.75mg/l) showed highest percentage of shoot induction (55.6±0.81) and multiple shoot regeneration. Combination of BA, NAA and KIN (6-Furfuryl amino purine/kinetin) found to be most efficient in shoot induction (60.7%) and multiplications (16.7±0.48). After successful shoot regeneration, regenerated shoots were cultured for root induction in MS0. The developed plantlets through in vitro culture technique were acclimated and successfully transferred to in vivo condition for further evaluations.
