October beans X Turkish runner beans

Bean seed on the left was saved from October beans  (I think)  about five years ago. I don’t think they are runner beans, but I’m not sure.  I believe they are still a pure variety. About
three years ago, I planted some with another variety that I think were called Turkish runner beans.  The seeds in the bottom picture are the result. I think the Turkish beens were pure brown. All the seeds are a lot larger than than the October beans. Some are larger than either variety. The largest seed is much larger and has colorations from both varieties.

I only had a few plants in pots. It was too hot and dry, so I only have a few seeds. I think they were good varieties. I had some health problems and couldn’t take care of them.

Are these a cross of two varieties or two species?  I think at least one variety was a runner bean because I remember tubers. Should I try to keep growing them and which seeds should I plant?I don’t have much room.

Hopefully, this is a better picture.
