grow runner
beans and collect some of the dried pods for the following years seeds.
Runner bean variety "Streamline" or at least that is what it said on the
original packet ten years ago! I've always found it a good strong
variety, pest resistant and the pods string-less. Could broad beans
cross pollinate with the runner beans and lead to hybrid bean seeds for
planting next year? I'm also assuming such crosses would not be
desirable?

Runner beans are Phaseolus coccineus and Broad beans are Vicia faba so
not even related so the chances of them crossing are rather remote.
"Not even related" is a rather extreme conclusion from the plants being
in different genera. However they are not only in different genera, but
also in different tribes. Intertribal hybrids are even rarer than
intergeneric hybrids.
Broad beans turn out to be more closely related to peas than to runner
beans.
