Abstract : Since the inception of the project in 2000 on 'Conservation and Use of Native Tropical Fruit Species Biodiversity in Asia', considerable progress has been made towards collecting, characterization, conservation, documentation, training and public awareness of identified species including citrus (Citrus spp.), mango (Mangifera spp.), jackfruit, litchi (Litchi chinensis), rambutan (Nephelium spp.) and mangosteen (Garcinia spp.). Approximately 3000 accessions of 6 fruit tree species have been collected and large amount of data on various characters obtained. For promoting, the use of these germplasm, it is necessary to access the genetic diversity of the fruit trees and provide useful information to users of genetic resources. This paper shows how the information gathered could be analysed in different ways to determine the degree of variability and how this could be effectively used in plant genetic resource conservation and utilization. The data available are no means exhaustive, and this attempt is to be treated merely as an example how genetic diversity could be analysed. The conclusions drawn and presented in this paper with regard to the genetic diversity and its distribution are valid only for the data made available on the target fruit species.
