*Doesn't look like he carries dumalis, but the USNA germplasm
repository does. http://www.usna.usda.gov/Research/WLPGR_NA_site.html
However, I've never ordered material from a germplasm repository and don't
know if they'd allow li'l ol' me to do so. Is it no big deal?*
Can't say. I've successfully gotten apple and strawberry accessions
through the germplasm repository,
but I've gotten the impression your success may depend on which
repository you are dealing with.
From the web site you gave, the line: "Not all
accessions are available for distribution. Accessions that are available for
distribution are for research purposes only to qualified institutions.
"
doesn't hold out much hope. You could try anyway. If they
reject you you haven't
really lost anything. In submitting your request, I wouldn't
outright indicate you
are not a researcher.
Best of luck.
