Abstract
Banana Musa acuminata cv. Berangan is an important fruit crop in Malaysia. The use of tissue culture techniques can increase the number of planting materials for mass production of banana. However the main problem in banana tissue culture is somaclonal variation which is caused by many factors such as long-term subcultures which can reduce the production value and quality. In this study the experiment focused on somaclonal variation caused by long-term subculture that had caused changes in their morphology which could be differentiated by RAPD pattern of micropropagated Musa acuminata cv. Berangan plantlets from long-term subcultures (15th subculture). Banana plantlets established from micropropagated banana using MS supplemented with 5 mgL-1 of BAP was maintained until 15th subculture before being hardened and acclimatized in commercial soils. In this experiment banana seedlings were categorized into four groups based on their heights at 5 - 10 cm 11 - 15 cm 16 - 20 cm and 21 - 25 cm. Results showed that the tallest seedlings (21 - 25 cm) produced 9.56 1.01 number of leaves 218.88 40.89 cm leaf area and 5.32 0.78 cm girth of pseudostem whereby the shortest group (5 - 10 cm) produced 5.67 0.98 leaves 18.95 12.37 cm of leaf area and 1.63 0.54 cm girth of pseudostem. RAPD analysis carried out using two primers OPH09 and OPA15 showed variation between the tallest seedlings and the shortest seedlings. This study concluded that long-term subculture of banana cv. Berangan produced variation in the seedlings growth thus may affect the quality of planting materials produced
