Prior to EE 2.6 when the relationship fields were rewritten, this block worked correctly to find child entries (program channel) who were NOT associated with a parent (program parents channel) using the relationship field {program_parent} :

{exp:channel:entries channel="programs" dynamic="no" status="open" orderby="program_display_order" sort="asc"}
    {if program_parent == "0"}
        <li> {title} </li>
    {/if}
{/exp:channel:entries}

Now, in EE 2.7.2, although there are new methods for accessing additional field content in the relationships between an entry in one channel and an entry in another, there appears to be no documented way to identify entries that are NOT associated.

Does anyone know of a workaround for finding entries whose relationship drop-down contains no value?

After reading this bug report: support.ellislab.com/bugs/detail/19820
it occurred to me that tests need to be more specific; e.g. to include a specific field. This code appears to do what I want by returning entries without parents.

{exp:channel:entries channel="programs" dynamic="no" status="open" orderby="program_display_order" sort="asc"}
  {if "{program_parent:url_title}" == ""}
     <li>{title}</li>
  {/if}
{/exp:channel:entries}
