Chuck Chapman responds:  I suspect that this is one of the multiple 
dosages of dominat amoena rather then a zonal. No evidence of plicata

Neil comments:
It would be difficult to say just what is going on with the 
anthocyanin heritage here, as there are multiple generations of 
the "I" dominant 'white' inhibitor hiding the anthocyanins in all 
directions in the ancestry.  I don't see in the first several 
generations behind this cross where the I(s) inhibitor might have 
been introduced.  

The only way to tell what is going on is to cross the seedling with 
a) the EC I(s) "Fred Kerr" banded amoena type and 
b) acknowledged zonals such as SUKY or Joe Ghio's TIME ZONE, or any 
plicata or luminata type.  If the flower pattern in this seedling is 
the result of any plicata allele the results will be obvious.

The quality of non-blue in the standards does suggest the I(s) 
inhibitor.

The same applies to the Lets Boogie seedling.  The only way to know 
is to make the crosses and observe the progeny.  The sparkling clean 
standards also do suggest the dominant amoena I(s) factor.  Or--this 
may be something entire different from either the possibilities of a 
dominant amoena variant due to dosage effects or an amoena-zonal.

Another fun possibility is to cross the two seedlings with each 
other.  If they have anything in common that will be obvious.  If 
they are something entirely different, that too will be clear.
