It is clear that potato varieties resistant to the CPB are
desperately needed by farmers and demanded by
society. Natural variation of wild relatives of potato
can be used as sources of resistance for the development
of CPB-resistant potato varieties. It is desirable
to combine different resistance mechanisms, preferably
affecting different life stages of the insect, which
will result in a more sustainable long term solution of
the insect problem in potato. From an environmental
and management point of view it will be good to focus
on broad working resistance mechanisms,.e.g.
mechanisms that affect other pest insects as well, in
order to achieve the cutback in insecticide use. Several
options for this seem to be present in the available wild
relatives of potato. Although there are barriers to
overcome, the newly developed technologies and
approaches can be used to solve the problems associated
with the introgression of the resistance from the
wild relatives into the cultivated potato.
