This overview does not include the countless number of lines used by scientists worldwide for special studies in diverse disciplines to develop bean populations with desirable traits or varieties*.

* The real number of varieties released is much higher because several of these lines served as basis for varieties released in more than one country (not reflected in tables), thus explaining why total horizontal sums are not exact.

Bush Bean Lines and Varieties of Different Market Classes Included in the IBYAN between 1976-1995 and Released as Varieties in Different Countries
