The Pisang Raja Banana belongs to the following taxonomic classification:
- Kingdom: Plantae
- Phylum: Tracheophyta
- Class: Liliopsida
- Order: Zingiberales
- Family: Musaceae
- Genus: Musa
- Species: × paradisiaca
- Cultivar: ‘Pisang Raja’ (synonyms: Raja Bulu, Grindy, Belle)
The Pisang Raja is a hybrid of Musa acuminata and Musa balbisiana, classified as Musa × paradisiaca to denote its hybrid origin. It belongs to the AAB genome group, a triploid cultivar with two parts Musa acuminata and one part Musa balbisiana, contributing to its sweet, creamy flesh and robust nature. Some local cultivars, such as Raja Bandung, may be classified as ABB, reflecting slight genetic variations. Pisang Raja is sterile, seedless, and propagated vegetatively through suckers or tissue culture, ensuring consistent fruit quality. The name “Pisang Raja,” meaning “King Banana” in Malay, underscores its esteemed status in Southeast Asian cuisine and culture.
History of the Pisang Raja
The Pisang Raja’s history traces back to Southeast Asia, where bananas were domesticated around 10,000 years ago in Papua New Guinea and the Malay Archipelago. Hybrids like Pisang Raja, derived from Musa acuminata and Musa balbisiana, emerged through natural and human-selected crosses, valued for their seedless, flavorful fruits. By 3,000 BCE, bananas spread to India, Indonesia, and Malaysia, with Pisang Raja likely originating in Johor, Malaysia, as a hybrid of Pisang Mas and Pisang Bakar.
Pisang Raja has been cultivated for centuries in Malaysia and Indonesia, where it’s a staple in local diets and cultural practices. In Java, over 40 local Pisang Raja cultivars, such as Raja Bandung and Raja Siem, have been documented, showcasing its diversity. The Portuguese, arriving in Southeast Asia around 1511, introduced flour-based cooking techniques, popularizing pisang goreng (fried bananas), which elevated Pisang Raja’s culinary prominence as a savory-sweet snack.
Unlike the globally exported Cavendish, Pisang Raja remains a local favorite, primarily grown for domestic markets due to its softer flesh and shorter shelf life. Major producers include Malaysia, Indonesia, Philippines, and Thailand, with limited exports to Europe, North America, and the Middle East. The cultivar faces challenges from diseases like Tropical Race 4 (TR4), prompting research into resistant hybrids. Its rich flavor and cultural significance continue to drive its global popularity, fueled by social media and specialty fruit markets.
Native Area
Pisang Raja Bananas are native to Southeast Asia, specifically Malaysia (Johor region), Indonesia, Thailand, and the Philippines, where wild Musa species thrive in tropical rainforests. The cultivar’s Musa balbisiana ancestry enhances its resilience in humid, equatorial climates.
Today, Pisang Raja is cultivated in tropical and subtropical regions, including:
- Asia: Malaysia (Sarawak, Johor, Pahang), Indonesia (Java, Sumatra), Philippines, Thailand
- Oceania: Hawaii, Fiji
- Latin America: Limited cultivation in Costa Rica, Colombia
- Africa: Nigeria, Ghana (small-scale)
Pisang Raja thrives in warm, humid climates with 100–180 inches of annual rainfall or irrigation, making it a staple in Southeast Asian home gardens and small farms. Its limited commercial export keeps it a regional delicacy, though it’s gaining traction globally.
Identifying Characteristics
- Size and Shape: Pisang Raja bananas are large, typically 20–30 centimeters (8–12 inches) long and 4–6 centimeters wide, with a cylindrical, slightly curved shape. They grow in compact bunches of 6–9 hands, each with 14–17 fingers, weighing 15–30 pounds.
- Skin: The skin is thick, coarse, and green when unripe, ripening to a greenish-yellow or brownish-black with dark spots. The skin is tougher than Cavendish, requiring a knife when unripe, but peels easily when ripe.
- Flesh: The flesh is creamy orange-yellow, firm, and dense, with a creamy, smooth texture when ripe. It is seedless, occasionally containing tiny, inedible black specks, and has a rich, buttery consistency.
- Stem: Fruits are attached to a greenish-brown stem within the hand, connecting to the main stalk. The stem is removed during processing.
- Aroma: Pisang Raja bananas have a tropical, intense aroma with notes of vanilla, caramel, and spice, intensifying as they ripen.
- Plant Characteristics: Pisang Raja plants are herbaceous perennials, reaching 6–20 feet tall, with broad, green leaves (up to 8 feet long) forming a pseudostem. The rhizome produces suckers for propagation, and the inflorescence emerges after 10–15 months, developing into fruit bunches over 3–4 months. Plants are monocarpic, dying after fruiting, with suckers continuing the cycle. They are wind-resistant and slightly cold-tolerant.
Taste
- Sweetness: Ripe Pisang Raja bananas are highly sweet, with a sugar content of 18–22%, offering a butterscotch or caramel-like sweetness that surpasses Cavendish. Unripe bananas are starchy and mild.
- Tartness: Ripe bananas have a subtle tartness, adding depth, while unripe ones are tangy and astringent, suitable for cooking.
- Flavor Notes: The flavor is complex and tropical, with notes of butterscotch, caramel, vanilla, and spice. Some detect a honey-like or custard-like quality, making it a natural dessert fruit.
- Texture: The texture is creamy, dense, and smooth when ripe, with a firm, starchy consistency when unripe. Ripe Pisang Raja is velvety and melt-in-the-mouth, ideal for fresh eating.
- Aftertaste: The aftertaste is sweet and lingering, with a caramel-vanilla finish that invites another bite.
Growth Rate
- Establishment: Plants grow from suckers or tissue-cultured plantlets, reaching fruiting maturity within 10–15 months in tropical climates. New leaves emerge every 7–10 days, forming a pseudostem.
- Mature Size: Plants reach 6–20 feet tall and 1–2 feet in diameter at the pseudostem, with a spread of 6–12 feet due to large leaves. Compact cultivars, like those sold for home gardens, may stay 6–8 feet tall.
- Fruit Production: After 10–15 months, plants produce a single inflorescence, developing into a bunch of 50–150 bananas over 3–4 months. Each plant fruits once, then dies, with suckers continuing the cycle. Harvests occur every 9–12 months in commercial settings.
- Propagation: Pisang Raja is propagated vegetatively, as it is sterile. Suckers are replanted, or tissue culture ensures disease-free stock, maintaining genetic uniformity but increasing vulnerability to diseases like TR4.
USDA Hardiness Zones
