As a comment about Daylily (Hemerocallis 'Double Sunshine'), bron wrote:

I was researching the ancestry of DOUBLE SUNSHINE registered as a Brown cultivar 1974. However, its registered date seems wrong given the later dates 1988 1986 and 1977 that are given for registration of its ancestors as per NGA pages and the AHS site.

DOUBLE SUNSHINE 1974 = Double Doubloon × sdlg
DOUBLE DUBLOON 1970 = sdlg x Double Gold ?! 1988 ?!
(( DD offsp incl Twin Classic 1977))
DOUBLE GOLD 1988 = Alpha Double ?!1986 !? x Condilla 1977

The ancestor parents DOUBLE GOLD, ALPHA DOUBLE and CONDILLA appear to have only come into existence after DOUBLE SUNSHINE did.
I have been working myself silly lately, but not that silly methinks ?????

I have a separate database of registrations up to the year 2000 that is independent of the AHS registration database. There are also printed checklist books of registrations. It seems as if the AHS computer database is in error for Double Doubloon.

The parentage I have shows Double Doubloon is from sdlg x Doublegood
Doublegood is Double Value x sdlg.
