Micropropagation of strawberry cultivar Sweet Charlie through axillary shoot proliferation

Abstract: A protocol for micropropagation of strawberry cv. Sweet Charlie was standardized through axillary shoot proliferation from runner tips. Medium supplemented with TDZ (1 mg/L) alone was favourable for the induction of multiple shoots and daughter runners from runner tips. Such shoots were successfully multiplied for four times on MS incorporated with 0.5mg/L each of BAP, IBA and 1.0 mg/L of GA₃. Rooting of subcultured shoots was achieved on MS medium containing 0.5 mg/L of kinetin alone and along with 0.5 mg/L of IBA. Ex agar plants were harvested regularly after three weeks of growth period for their acclimatization in both cocopeat and soil. The survival rate of tissue cultured plants was 85%.
