So, are the ones you stole F1?

I'm assuming all the ones that are sold in the UK have been stabilized and therefore breed true..

No idea.  I would assume not but I really don't know. They are almost certainly from a USDA accession. Which one i don't know either. All I know is there were two rows (presumably 2 different accessions) and I grabbed at least one pod that was mostly developed.

If you search Phaseolus coccineus a number of hybrids show up.

They sure collected a lot of "hybrids" from Sweden.  Which might not be hybrids at all.  When I tried for more information, all that was written was that 'hybrid' was what they called seeds that did not have an acceptable binomial.  No mention of which species might be involved. 

P coccineus was mostly from its native area, except for one accession from India.

It would be fun to grow a lot of them. Is anyone planning to?

Diane, you might have clicked on the wrong link. You need to click on the accession number to get the more specific information.

https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?id=1156574

This one from Germany says this:

Description: Phaseolus vulgris X P. coccineus (Granda X Erecta)

Yes, that works better.  I didn't look at all of them, but the German ones I checked were mostly vulgaris X coccineus (Granda X Erecta).  One was a backcross to vulgaris.

The Swedish ones were also vulgaris X coccineus

So, does the cross work best in that direction?

Yes. It works best with runner beans as the pollen donor.
