Oliver, 2003). A better understanding of the diversity
of coconuts that are available in farmers′ gardens
would also help to utilize the range of germplasm for
the sustainable production of coconuts, to increase the
income of farmers and to make conservation strategies.
Selected palms from these communities will be used
as sources of seed nuts for planting, and community-
managed seedling nurseries will be raised. This should
serve as effective

mechanisms for the introduction and promotion of
farmer-preferred coconut diversity that could
effectively support sustainable coconut production.
Meanwhile, our results showed that it is a powerful
tool to address issues in individual assignment,
population assignment and sibship reconstruction by
combining the multi-locus SSR fingerprinting data
with the model-based statistical method for individual
assignment. Our study significantly improves the
understanding of the earlier coconut collection from
the Hainan province by clarifying and adding the
passport data, which were largely missing in the
records. In addition, the information on population
structure, genealogical relationship and genotype
identity in this germplasm group will be submitted to
the International Coconut Genetic Resources Network
(COGENT). This information will improve the
efficiency and accuracy of coconut germplasm
conservation, since inadequate representation of
genetic diversity in the germplasm collections is
another major constraint for efficiently conserving the
genetic diversity of coconuts. The wild germplasm in
the existing collections is primarily acquired during a
few collecting expeditions, with the majority of them
obtained in plain. In our study, a lot of wild
