The wild grapevine (WG) (Vitis vinifera subsp. sylvestris
Gmel.) is a very rare and endangered plant subspecies. It
is the wild relative (ancestor) of the cultivated grapevine.
Characterization, evaluation and conservation of WG resources
is a process that is carried out in different ways and with
varying intensity in European countries. However, there
are WG habitats that have not been recorded and investigated
at all. Therefore, there is necessity for joint action of
ECPGR Vitis group to raise and harmonize the efforts for
conservation of WG populations.
Task 1 - Review of existing EU bibliography of wild grapevine
inventory of available bibliography of WG natural habitats
will be done as a first step in situation assessment. Other
available information of WG populations in Europe will be
collected within the ECPGR partners. Historical data about
the presence of WG populations (reported in less accessible
literature) will be specifically investigated and compared
with the present knowledge about these populations in order
to assess the level of threat.
2 - In situ and ex situ protection
partners will define the indicators of vulnerability for
WG populations. From past experience it is evident that
it is not possible to deposit each individual into ex situ
collection. Additional protective measures on natural habitats
must be undertaken, especially for particularly sensitive
and vulnerable populations. We will consider how to involve
other stakeholders in in situ conservation (e.g. National
parks, Botanical gardens, etc.). Propagation of WG individuals
into ex situ germplasm collection is very delicate work.
Protocols for propagation and ways how to preserve maximum
genetic variation in ex situ collections will be discussed
within the group.
3 - Characterization and evaluation data on wild grapevine
the framework of past EU projects (GenRes081, GrapeGen06,
COST FA1003) descriptors and protocols of grapevine evaluation
were adopted. However, WG populations are very specific
for a series of reasons (such as natural growth without
human impact) and require special attention in evaluation
of morphological characters. Morphological similarity with
cultivated grapes and some rootstocks is quite large. In
some cases there is a possibility of error / replacement
in identification. We will select most suitable (the most
discriminate) descriptors for WG identification and evaluation.
At the level of genotype available data at nine SSR markers
(standard set for identification, agreed within GrapeGene06
project) will be compared in order to detect specific (unique)
alleles in WG populations.
