Coffea canephora was first introduced into Java in 1900 from Congo. C. canephora is now cultivated in tropical regions throughout the world. Selection programmes in East Java resulted in high-yielding plant material, which formed the basis for C. canephora production not only in Asia and major producers being Indonesia, Vietnam and India - but even in tropical Africa.
