Abstract. Musa paradisiaca L. or Raja Bulu banana are climate change-resistant plants, characterized by the ability of the stem to store water hence it can survive under drought conditions. Leaf size is wide and long and a large number then the banana leaf is a provider of oxygen through photosynthesis for human health. One of the weaknesses of Raja Bulu plantain is its long harvest live which is between 12-15 months making it less effective to meet market demand. The efforts to get a banana plant with superior quality can be improved the varieties through plant breeding programs using gamma-ray irradiation. Raja Bulu banana has been acclimatized to the land as the first generation (MV1). This research is an attempt to obtain short-lived banana cultivars in order to provide faster harvest time and increase the population of banana plants as a food source and a source of oxygen for human health. Early maturity of the harvest is one way of avoiding changes in the dry season. The results showed that the Raja Bulu banana with irradiation treatment 20 Gy, 25 Gy, and 20 Gy provide a diversity of character growth on the generative phase compared with Raja Bulu banana without irradiation treatment. Raja Bulu banana with irradiation treatment dose 20 Gy in sample R4 28 become individual selected that has character early maturity harvest 343 DAP (Days After Planting).
