Ales,

According to the following link
http://www.agriculture.state.pa.us/agriculture/cwp/view.asp?q=128173 there
are several different strains of Sharka and strain M can be transmitted
through seed.  However I found some research indicating it can't be
transmitted through seed
http://www.blackwell-synergy.com/doi/abs/10.1111/j.1365-2338.2006.00989.x

I guess I've never seen Prunus from Europe in this area, although have seen
plenty from South America.  Are you sure your not seeing Hungarian or
Romanian "cultivars" (that were grown in North America) in our markets,
verses something actually imported from Europe?  According to a USDA list of
countries eligible to import plums into the U.S., no European country
(except Belgium) is eligible to ship plums in the U.S.

> Dear friends, don’t worry about the seeds. They are still sleeping in
freedom in the cellar over the ocean in Europe. It was just an idea for
future. But if it is illegal we stay rather in theoretical level.
> If we are asking who is carrying diseases to ours lands we should have a
look to the big corporation importing fruits in to the supermarkets. You can
find nice Hungarian and Romanian plums in North American markets. (south
Europa is considered to be an origin of Plum pox).    One is realy surprised
(after hearing hysteric messages about spreading new illnesses from abroad)
to find nice Californian peaches in Germany ornamented with fresh peach
leaves on the top of it!!!
> By the way: Plum pox in Europe known as Sarka can not be carried by the
seeds.
> It is true that this disease destroyed about 80% of the nicest population
Prunus Domestica. But instead of crying and be narky we should ask our self
why it has happened? In last few centuries P.d. was almost entirely
propagated by suckers. There is a big population of clone trees without any
generative reproduction, which is the only possibility to change genetic
properties with regard to growing conditions. So we don’t supposed to be
wondering that once upon a time some weak beings are attack by diseases what
is only the natural reaction of universe to get rid of the unable creatures.
> That’s why we decided years ago to start to propagate fruit trees from
seeds. We do use grafting and cuttings propagation of course. But more as
middle step to have a wide scale of varieties for beginning with selecting
seeds.
