Abstract


Except for potato, sweet potato, taro, yam, and
cassava, most of tuber crops are considered as underutilized
crops. However, tuber crops are potential as alternative
carbohydrate sources, so they can be used as food reserves
to face global climate change that affects food security in
certain area throughout the world, including Indonesia.
Having high diversity in tuber crops germplasm, Indonesia
must be able to conserve those germplasm to ensure their
availability in the future. In the future, without ignoring all
the probable constraints, the prospect in utilization of in vitro
culture technique will be higher for improvement of
conservation and management of genetic resources in the
form of active and base collections. In this paper, strategy in
developing in vitro collection of tuber crops germplasm, i.e.
slow growth technique for medium term storage and
cryopreservation technique for long term storage, is
discussed including how to analyze genetic stability of the
collections. Several national and international research
centers dealing with research and development of in vitro
conservation technique are presented.


Keywords
