Abstract


The genus Baccaurea consists of underutilized and threatened fruit species.
Baccaurea species can be found in the forest, however they are also grown in the home gardens and orchards. A survey of Baccaurea species was carried out in 25 home gardens and orchards in Malaysia. A total of eight Baccaurea species was found cultivated and semi-cultivated in the home gardens and orchards. B. motleyana was common and widely cultivated. Baccaurea brevipes, B. velutina and B. reticulata were rare species found. The highest number of Baccaurea motleyana trees was found in Sarawak (152). The highest number of species was recorded in Sarawak and Pahang (5 species) however the species
diversity was low in Sarawak (Shahnon Index, H = 0.672) which is due to the uneven distribution of the species. Eight Baccaurea species cultivated viz. B. angulata, B. lanceolata, B. macrocarpa, B. motleyana, B. polyneura, B. ramiflora, B. reticulata and B. velutina for ex situ conservation at MARDI germplasm at Jelebu, Negeri Sembilan. B. motleyana was the first to start flowering after 3 years of planting followed by B. macrocarpa, B. polyneura, and B. ramiflora. Baccaurea macrocarpa is the potential species for large scale planting due to the good fruit quality and short juvenile period.
