| Summary: | Since jackfruit (Artocarpus heterophyllus Lam.) was introduced to Java Island
about 2000 years ago, this fruit tree has been utilized with various purposes in
villagers� life until now. Researches for variability of jackfruit were conducted not
only from morphological aspect but also from genetic aspect in India and
Bangladesh, origin region of jackfruit. However, variability of Indonesian
jackfruit has not been known. Information about variability and traditional uses of
jackfruit population need to be recorded, especially in Java Island where the
urbanization is more accelerated than other Islands and more than 60% of
Indonesian population live, before various jackfruit population and local
knowledge are vanished. The information is very important for conservation of
land race and breeding economic cultivars. Objectives of this research are to
obtain information about morphological variability, fresh fruit quality, and local
knowledge about folk plant uses of jackfruit, then discussed relationship among
the information and gave advices for jackfruit cultivation and the breeding. 125
jackfruit collections were observed to obtain morphological information and fresh
fruit quality throughout Java Island. By using principle component analysis and
cluster analysis, all sample trees were categorized in 5 clusters based on fruit
morphology and in 4 clusters based on sensory attributes. From one cluster based
on sensory attributes, 5 trees which produce high quality fruits were selected.
