Yes the pink/red beans on the right all come from one plant I will definetely grow out these seeds next year and share.
I think my Anasazi seeds were indeed not pure-breeding. I bought them in a Whole foods store in Florida last spring. These seeds were sold to be eaten so unpure breeding is possible if the grower grows many varieties which is often the case. But I thought beans would not cross this easily.
What is the sowing distance to respect between 2 varieties to maintain pure breeding with beans ?
Ok, could be cross or mutation. Mutation will come true again, the change is fixed and will be the same in the future. With a cross you will see the big F2 generation variation when you sow these beans.
The safe distance is difficult to determine. Beans self-pollinate usually before the flowers open. But wasps can bite into the back of bean flowers to get at pollen and that can result in crossing. Depending on where you live in the world, the crossing danger is hardly a problem or much greater. In the pacific north west of the USA it is hardly a problem, in Southern states much more so. Rather than isolating distances you can ensure absolute seed purity by bagging individual flower trusses with fine mesh little see-through sacs that are tied above a flower truss. Bridal veil or see-through curtain material is used for blossom bags. These are hand stitched, easy to make, to use.and reuse.
Whenever you have OP seeds it is just possible that accidental crossing has taken place. Easy enough discard non-standard beans or to have a bit of fun and follow them up :-)
