Hyb:Genetics


Hi all,
I have the following Iris in my garden:
Elisabeth Noble (K.Smith 1955)		
White standards, Royal Bluefalls, white beards, recessive amoena
(Helen Collingwood*(Extravaganza*Ticonderoga))Grandchild of Wabash.
Is this iris diploid? If so is there any hope (or point)of breeding from 
seedlings produced from a cross with 'Creative Stitchery' a purple 
plicata. All my first cross seedlings should be purple selfs.

Q2: The Pumilla spot appears to be dominant, as it is appearing on 
crosses with T.B.'s. Is it a single genetic trait, or does it involve a 
number of genes?
 
Q3: 'Burst' (Blyth 93) is yellow with a large red burst on the falls 
(like a pumilla spot). He insists that this is really a fancy plicata, 
and it's breeding suggests this (Swain x (Mountain Melody x Polished 
Amber)). Why the odd colouring?
