As Clarence is trying to explain here, there were two separate threads in
his original posting, which have gotten tangled together:
1) The Aril ancestry of EARL OF ESSEX; and
2) The source of the dominant amoena trait in modern TBs in one or
the other of two non-aril dwarf bearded species used by Paul Cook to

No, EARL OF ESSEX is a typical plic with colored edging on the white ground
of both the standards and falls (only the Arilbred ancestry comments by
Clarence apply to E of E, not the dominant amoena ones).

Do not attempt to place too much emphasis on the Aril inheritance of E of
E; the Aril ancestor is remote, and E of E has less than 1% Aril genes in
its total genetic composition.

Schreiners registered STEPPING OUT as "parentage unknown", so there is very
little ancestry to root through. JESSE' SONG resulted from the cross of two
seedlings. The four grandparents were all registered cultivars: CHARMED
CIRCLE (Keppel), KISS (Knocke), SMOKE RINGS (Gibson), and DECOLLETAGE
(Hager). I think it is this diverse genetic background from four separate
breeding lines that goes a long way to explain J S's robust performance
under most conditions.
