You can get it in Malaysia, Indonesia, Phillippines etc
Varieties
Since rambutan is a cross-pollinated crop, large genetic variation has occurred in nature over generations and numerous varieties have been identified but their nomenclature is confused. Most of them can be distinguished by spine length, fruit wall colour, aril thickness, aroma, adherence of aril to the seed, vitamin C content and fruit set. Rongrien and Chompu are most popular varieties in Thailand. Both these have crisp arils and are well-suited for canning and for fresh consumption. Bingjai, Lebak Bulus and Rapiah are important varieties of Indonesia, which have sweet, sub-acid and very sweet pulp respectively. Bingjai has long spines while Rapiah fruits are smaller. Some of the good varieties like Azimal (thick aril, sweet to sub-acid pulp), Kelip (medium thick aril, very sweet) and Singapura (thin aril, very sweet) are grown in Malaysia. Trees with male, female and perfect flowers are known in rambutan, but most of the cultivated varieties are generally monoecicus, bearing male and female flowers on the same tree.
Propagation
Most of the varieties as mentioned above are of seed origin, but scientifically use of seeds for propagation is discouraged in rambutan culture for two reasons: the progeny varies with uncertain performance and occurrence of both male or female trees. The male trees not producing a crop while the female trees require pollinator to bear well. Hence, vegetative propagation is advocated to maintain the genetic integrity of a variety.
For rootstock purpose, fresh seeds are planted in humus-rich medium with good drainage. Seeds germinate in a fortnight. At 3–4 leaf stage, the seedlings are transplanted to polybags with minimum possible damage to roots. The seedlings are ready to bud when the stem has attained a diameter of about 15 mm. Sometimes due to iron deficiency rambutan seedlings show chlorosis (yellowing of leaves) which should be corrected immediately by appropriate soil amendments. The modified Forkert (modified patch budding) using mature budwood, and approach grafting or inarching are the standard techniques used in propagation. It is also clonally multiplied through air-layering in India, Malaysia and Indonesia.
