Me. Dulloo et al., Complementary conservation strategies for the genus Coffea: A case study of Mascarene Coffea species, GEN RESOUR, 45(6), 1998, pp. 565-579
No single conservation technique can adequately conserve the full range of
genetic diversity of a target species or genepool. To optimize the efficien
cy of germplasm conservation, a range of conservation techniques needs to b
e applied simultaneously. In this paper we review the progress made in the
application of both in situ and ex situ complementary conservation strategi
es and techniques to the conservation of the genus Coffea and identify area
s where more research work is required. Traditionally, Coffea species have
been conserved ex situ as living plants in field genebanks due to their int
ermediate seed storage behaviour. However, progress made in the field of bi
otechnology in recent years have made it possible to envisage the use of in
vitro, slow growth and cryopreservation for medium- and long-term conserva
tion of Coffea germplasm, respectively. In situ conservation is also an imp
ortant option for long-term conservation, but there are no genetic reserves
specifically set up for conserving Coffea. Protected areas and managed res
erves offer the best opportunities for conserving Coffea. A case study for
Mascarene Coffea in Mauritius is presented and a strategy for their conserv
ation is discussed.
