Re: Ribes + Polygonatum

Dear Marc:
  You might want to save all the ungerminated seed and stratify it again.  I
found that a number of lots of seed that I handled didn't all germinate the
first time.  In some cases, some seed didn't germinate until it had been
stratified at least three times.  I've had seed that came up three years
after it was planted.  Also, some seeds need to be scarified - treated with
acid or otherwise have the seed coat broken down some.  
  There is a man right there in Belgium, Peter Bauwens, "Peter Bauwens"
<p.bauwens@ping.be> who has a very extensive collection of Ribes varieties. 
Also, if you want to try species, you should contact the National Clonal
Germplasm Repository in Corvallis, Oregon.  That is where the U.S.
collection of Ribes is kept.  I worked there for a year, which is where I
got most of my practice germinating Ribes seed.  The curator is "Kim Hummer"
<hummerk@bcc.orst.edu>  She will probably be glad to help, especially if you
have any varieties or species that are needed in the collection and would
like to trade.  There is no cost, either. If you want to see what the
collection there is like, go to my web site and find the link the California
Rare Fruit Growers (CRFG) and look for the link to the NCGR in that web
site.  The NCGR has a complete online catalog.
  I would also be glad to put you in touch with Ribes breeders elsewhere, if
you like.  For example, there is a man in Sweden who has done some private
breeding of Ribes. "Ake Truedsson" <Ake.Truedsson@CEMENTA.scancem.com>  has
introduced White Giant white currant, through the Balsgard Breeding
Institute.
  Also on my web site you will find a link for NAFEX, and on that site is a
link to a man with a very large collection of Ribes, Mr. Ed Mashburn.  
  There are more, but this is probably all you want for now.
