A fruit of mabolo

            Mabolo is a very beautiful dark red to purple colored fruit with velvet-like skin.  In fact the word, “mabolo” in the Philippine language means “hairy”.  So the name “Mabolo” has been assigned to it because of its hairy surface.  Mabolo is higly esteemed locally but is virtually unknown in other parts of the world.

            The tree is often planted for its rather sweet but dry edible fruits, and also as a roadside tree.

            Mabolo is a very productive fruit tree. The fruit, however, lacks sweetness and is rather dry, making it less popular than many other tropical fruits.  There is a need to select superior clones.
