Banana (Musa spp.) cv. Rajapuri Bale (AAB) is a popular cultivar of banana grown in Northern parts of Karnataka especially in Bagalkot, Bijapur and Belgaum. The demand for the planting material of this cultivar is high and tissue cultured plantlets is not available because of the inherent problem in the initial establishment of the culture and multiplication rate is also low. For facilitating large scale multiplication of this cultivar, the present investigation was carried to out to optimize shoot proliferation with 6-Benzylaminopurine (BAP), Thiadiazuron (TDZ) and 6-Benzylaminopurine (BAP) with α- Naphthalene acetic acid (NAA). In the present experiment, multiple shoot clumps were cultured on MS basal medium supplemented with different kinds and concentrations of cytokinins. Among different cytokinins, BAP 4 mg/l was recorded as the best concentration for shoot growth parameters like per cent regeneration (100 %), days taken for bud sprouting (5.41), number of shoots per explant (3.13), number of leaves per shoot (2.07), shoot length (4.72 cm), chlorophyll content and fresh weight of the plantlets (3374.80 mg/plantlet) for banana cv. Rajapuri Bale.
