Abstract

Banana is a nutritionally as well as economically important plant for which (Basrai variety) an efficient micro-propagation protocol was developed by using micro-stem cutting, as an explant. The maximum numbers of plantlets with higher chlorophyll and lower carotenoid contents were observed, which developed through routinely used tissue culture system (10.0 µM BA; 8.0 µM IAA; 3.0 g/L phytagel) for organogenesis, permanent immersion system (10.0 µM BA; 1.0 g/L phytagel) for shoot induction and temporary immersion system (10.0 µM BA; 2.0 g/L phytagel) for shoot multiplication. The developed plantlets were cultured on 0.5 MS medium with IBA (0.01 mg/L). Rooted plantlets were successfully transferred to field after initial acclimatization.
