MARDI has opted ex situ conservation approaches to conserve plant genetic resources for food and agriculture (PGRFA). The method used for ex situ approaches are seed genebank as well as field genebank. Regardless of some disadvantages in the measures taken, the effectivesness of this method is proven to reduce impact of extinction and PGRFA losses....

The cultivation of Baccaurea species using seeds can produce fruits within 3 – 4 years after planting in the field if a systematic management is followed. Fruits from rambai family, even though do not belong to the commercial fruit species, may attract fruit lovers to eat them because of their good taste and rich in nutritional value.
