Musa acuminata cv Berangan is a Cavendish type banana that is popularly grown in Malaysia. This experiment was carried out to evaluate the field performance of Musa acuminata cv Berangan in the field treated with different BAP concentration during in vitro. The aim of this study is to compare the performances of the tissue culture seedlings produced from the different concentrations of BAP during in vitro and their adaptability in the farm. Furthermore, to identify any possible somaclonal variation showed in the plants. Plants treated with 0mg/L, 5mg/L, 10mg/L and 15mg/L of BAP were planted in the field for 12 weeks. Parameters measured were leaf length, leaf width, and numbers of functional leaves, plants height and the size of pseudo stem girth. The results show that the plants treated with 5mg/L of BAP shows vigorous growth than other treatment. Further studies need to be conducted until flowering, fruiting and
harvesting stage to help selection of the plants with good agronomical characteristics
